USA, packet data reception issues on AT&T :( - Galaxy S II General

OK I am giving up. My first ever complain thread related to any phone I ever owned.
The 3g/4g reception on SGS2 - am I the only one with a not acceptable reception on AT&T in the States, New York City in particular?
I used to have the Captivate, and at work I would always get bad reception: it would show a bar or two or 3, but it would ALWAYS stick with that and stay on the data network. So basically speed would go down, but the connection would still be present, if I am downloading something.
My Captivate was stolen. So a month or two later I buy the SGS2.
It seems the same at first - not ideal data connection.
But now I am noticing a very annoying thing. The phone would constantly switch like crazy between E, 3G, H, H+, and would sometimes DROP data connection altogether. When it drops the connection I have to either reboot it, and it comes back on H+, or I have to put it on the window sill where the signal is better, and then the signal will get reacquired in about 5-10 minutes (not immediately).
What is wrong?
I have the latest firmware from last night (the problem existed before too).
The phone is not rooted, and has minimal apps installed. Only gmail is set to push, plus the default widgets. I did try factory reset 2 days ago.

I'm not certain with this phone but I have owned several that once they lose the data connection and cant find it for a set time they stop looking for a period of time before recommencing a new search. This to save battery. While it doesnt speak to your problem directly I live in a low signal 3g area and I actually get better speed by switching to edge only than I do on 3g and without the hassle of it constantly losing its signal and then switching to edge, back to 3g, etc. Another thought is that it does not have to be your phone, it could be a tower issue.

its possible that since the SGS2 antenna is located on the bottom back left of the device, this time you are experiencing worse signal attenuation from your hand blocking the antenna. have you tried sitting the phone on the desk or table and see if it is any more stable? if so then you may have to learn to hold the phone with the antenna exposed away from your hand.
if none of that works, then i dunno...

I am ALWAYS placing the phone on wooden desk when I test connectivity
I agree that it may be disconnecting and waiting for longer time , to save time, I am just curious why my old Captivate did not do the same thing and worked my better in terms of reception.
I ALWAYS could rely on 3g on the Captivate.
Now with my SGS2 on my desk, I look at it and it shows no data, and the emails are not synched, etc.
Extremely annoying.

ok so now i noticed more people are facing this problem. i am wondering if this is a hardware or software fault.
look at my post

regards,

Same here....Data network absolutely is rubbish and I live in the middle of a large City!!
I get disconnections, slow or broken downloads, network errors and constantly changing from H, 3G, E, G. Seriously its like going back to WAP! its unusable i cant even check e-mail reliably unless im on WiFI thank good im on BT broadnband with its FON & Hotspots.
I.m on Orange in the uK, Ive flashed to KE1 but not KE2 because that has problems with Orange...grrrrr I was on O2 before on an iphone at it was reliable at least. I am just going to put mu orange Sim in my ipone to see how it goes......
Spoiling the love of this otherwise fabulous phone.

Hmm it's odd
my phone isn't connecting to the data service either. Are you on medianet or smartphone plan? Also one of my co-worker's iphone isn't connecting either but another one did barely hitting 1mbit. Anyone else from nyc having issues with data service?
I just rebooted my phone for the first time ever and it's showing servers in kansas as the closest server for speedtest.

I'm in NYC and have had not so ideal connections the past couple days. It was fine last week. Now when I run the speedtest app, I get spikes in the packet speeds (like Dirac functions) and the results are always inconsistent
i just ran the speedtest and the server was in Sayreville, NJ

i am having the exact same issue..at least yours keeps switching the band..on mine..once it looses 3g it wont even switch to edge..just disconnects the data connection..until i reboot or cycle thru the flight mode.if i force it on gsm only than the data connection is solid on edge..but whats the point..i need a fast data connection...and this is the most important thing that i need on a phone..good and fast data connection..for voip and other apps.my previous phone, desire hd does this band switching smoothly and does not loose data connection.

First, one of the advantages of an international non-branded phone is the lack of carrier modifications and crapware. The downside is the radio is also not optimized for a specific carrier's network. That's the answer to the different behavior between the Captivate and SGS2.
Second, New York's the worst possible market to comment on AT&T's network performance. The problems and congestion they have there are legend. Also, if they're working on the network (EG: upgrading more back haul) you're going to get funky performance while they're doing it.
Third, my Arabian friends, this has nothing to do with the issues a handful of you are having.
I'm in a smaller market with little congestion and mine phone works flawlessly and consistently. Like everyone else, my phone drops from H/H+ when no data's being transmitted but kicks back in instantly when needed.

Just hit 5424kbps/1254kbps on Speedtest using a local server. Could it be a regional issue in NY?

well a wonderful thing happened today.
people were calling me all day on the office number and asking "why do not you pick up your cell?"
I look at the cell , see 5 full bars on it and think to myself that they must have dialed a wrong number by accident.
Eventually I get suspicious, and dial my cell from my office phone - sure enough, it goes to voice mail after about 6 tones.
I had 5 bars on the phone. I then tried walking close to my office window, and even went downstairs and outside of the building. Still 5 bars, but can't reach that number. And when I tried calling FROM sgs2, it would just say "dialing" and then "call ended" after about 30 seconds of silence.
It took a phone reboot to properly get on the network.

Odd.
One of my co-worker said he had called me in the morning to see what i wanted for breakfast but i didn't pick up. Unless i received the call while i was in the elevator, i would have noticed the call. It didn't have a missed call notification or show up in the log.
Also i was able to use the phone during the day without a reboot.

I just reran the tests, it looks like my speeds are back to norm.
Just clocked in 4.38, 3.86, 4.7 and 5.75 down and 1.41,.97, 1.26, and 1.45 up. For those of you in nyc, run your tests again and see if it works

Have you tried forcing 1900 or 850 to see if that helps? I'm near Scranton, Wilkes-Barre, Hazleton in Pa, and 1900 does have a much faster ping and more bars, but 850 is generally faster and more reliable. In my particular case of course.

As further support of data being dormant on purpose, the Music Hub just popped up a dialog when I launched it that said "Activate data? Charges may apply." I get to NYC pretty frequently, you guys are really making me look forward to it.

I have not yet. I admit I panicked and bounced the phone Thought the phone just self destructed inside or something - never ever have I had a problem like this on AT&T in NYC in my 15 years with AT&T.
I can vouch this also never happened with my Captivate that I got on its release day.
Next time this happens I will try forcing bands.

i've had a few instances of network connectivity issues with my captivate where i couldn't connect. That could have been from the custom rom. Now my buddy swears that he gets barely any network connection at his apartment
Anyways i'm getting much better network performance now. Even better than before

I spent the majority of the day today in NYC and definitely experienced this, I actually tore through my battery completely bc of the lack of consistency with data connection. I even gave up checking xda.
I cannot wait till we have different modems to test!

Turn HSDPA mode off and "pure" 3G mode on

I've recently bought the HD2, former I ownt the TyTn II and th XDAII
Now I want to turn off the HSDPA data connection (The "H" icon appears in the taskbar) I only want to hav a "normal" 3G connection!
Can somebody help me to finnd the switch in the settings to do this!?
Cheers Chris
Why would you want to ruin your cellular data connection?
Connections > Advanced network...disable HSPA. Soft-reset.

1) If you're in an area with low to nonexistent HSPA, having it on will drain your battery immensely as it searches for signal as you're surfing.
2) Similar to #1, using EDGE or 3G will reduce battery consumption because data pulling will be less intensive.
3) if you're not doing a lot of streaming and only use your phone to read websites and/or update stock/weather/twitter/fb/etc, having it on EDGE or 3G produce similar results.
I can't believe I'm listing the options as to why the original poster would want to limit his data to just 3G, but I guess I shouldn't give too much credit to the kind of people who post on this forum.
HSDPA - isn't it working only under umts? I have EU HD2 - GSM model, should I turn it off permanently?

uhh what? Do you have an "H" symbol on your HD2? If not, then there's nothing you should be worried about.
nor really an bump but
HSDPA is not very reliable once single levels get below 100/95dbm (or 2 bars some times 3 as it does not always update in real time)
other note if H is enabled the phone will waste time trying to connect to an H signal that's not there or mite just be in range but is not
on my HTC HD1 the phone works 95% of the time with UMTS basic 3g some calls are diverted, but with HSDPA it sucks more power and more of my phone calls get diverted on an daily basis (diverts to my other network phone when phone not connectible, not stating networks as its the phones Fault for connecting to an H or 3g when it should be on stepping down to 3g then 2g due to signal) norm as i use my phone for business use i leave the phone on 2g only so (my other phone that's an htc desire i norm do use the h on it as it tends to play nice and drop to 2g when it should normally)
any way my phone is not the issue as i have the benefit to disable H speed and use 3g (umts) on the htc hd1
i have the hd2 phone here right now but the phone keeps on insisting to stay on H when single levels are poor and resulting in txt'ing only working , forcing the phone onto 2g fix's the problem but norm 3g coverage is fine
is there any way to turn off H on the hd2 like the hd1 can or is there custom firmware that adds the option or adjusts it so its less aggressive
don't know why we are bringing this up from the dead, but I get great download speeds with only 1-2 bars of hspa (+). I can't see why I would want to turn that off.
And to the poster that says edge works fine for most things, most of my updates time out trying to update on edge.

i hate edge.
the thread was never answered correctly (users posting on how good H is over 3g but from where i am its not so good as its turning the hd2/1 into an iphone 3 dropping calls wise when 3g/H is enabled) also turns the phone into an oven compared to umts mode and phone only lasts about an day with H enabled (2-3 days UMTS, 3-5 days 2g/GPRS depending on use)
3g?UMTS {most reliable for 3g} > HSDPA > HSUPA think there is an H+ as well for 7.5mb support
2g> gsm/gprs is king for keeping signal levels (EDGE unknown as I never get it but should be the same as GPRS) as there are more 2g towers then 3g or 3g/H towers, not cost affective to upgrade them all to 3g
one thing i not done yet is update the phones firmware as its still running on an 1-2 year old os this HD2 (uk t-mobile), the radio on it is 2.04 as well (my HD1 is 2 years or older) some one did post that it is in settings > adv network {was an older post that i found on google} that is missing on this currant HD2 phone i have
Most of the UK networks have not upgraded to edge around where I am so its GPRS or 3g/H
Some ROMs have the Advanced Network control panel applet in Settings/Connections where you can disable HSDPA and HSUPA.

I believe the relevant registry setting is at registry key HKLM\Software\OEM\RIL - DisH (Where a value of 0 disables HSDPA/HSUPA, 1 enables HSDPA and 2 enable HSDPA/HSUPA, reboot needed)
That was very useful comment I try it when I get back home later on (should really update the firmware as well the HTC touch flow is quite unstable on it)
i dont know where the problem is.
start -> settings -> connections -> advanced network.
there u can choose "disable hsdpa / hsupa"
bling, u got no H anymore..
if u use sense, u have to go via the windows settings, u cant change that in sense settings tab i think

i have to ring him on his G1 phone, if i ring the HD2 i get 2 things that happen its not connect (5 secs then the peeps call not conencted) or he answers it and it disconnects after 2 seconds
mite flash the device i never done it my self so mite do it on my HD1 first as mine is running on winmobile 6.2
--------------
i use an blackberry 8520 as an test at this time, was only £100 for it but i am missing the touch screen but like the idea of the 9800 having both screen and slide out pad but i prefer the windows phones input calendar points (hoping the win7 way be the same or like it)
that seems to have worked, did not seem to take it on the first reboot,was set to gsm only, set to auto was doing H still, still set to auto and powered down again and pulled the bat (prob did not need to) no h any more phone has constant 2-4 bars now on 3g (before 1-2 bar or drop call, on H if the phone was picked up 4 bars idle) can use phone and internet (was an fast call test was stable an clear not breaking up) should also stop it turning into an oven as well (as my HD1 does with H enabled), 3g is fine with opera as it has the turbo feature so web pages load fast still
give you rep if i could
i am not new to these forums but i have not done any messing with rom as my HTC HD1 one is currently just an unused PDA so i will have an go with it just need to look at the updating guides (need some class 6 sd cards as well all the ones i got are class 2 and are bit slow) if
once i have played with my hd1 i update the HD2 as that is an active phone (but needs updating on both phones as the default htc touch flow is an bit of an ram or cpu hog making the phone unstable, i disabled the touch flow on my hd1 as preventing phone call answer from working after 2-3 days as i needed it for business use but i like the default windows mobile layout anyway but i also like the htc layout when it works but must work all the time)

How Many People Are Having MAJOR PROBLEMS with DATA on T-Mobile HD2(Stock Rom)

Because this is F'ing ridiculous. I'm soon going to be on my 3rd HD2(T-Mobile is shipping me a new one tomorrow) the previous 2 just kept dropping my data connection. After about 3 hours of LESS of use my data would go out and only way to fix this is by doing a soft reset which is absolutely ridicules considering the damn thing just came out not less then 3 weeks ago. Am I just having bad luck or is there really an issue here that either T-Mobile or HTC need to address ASAP?!
UPDATE
ok now im starting to think it was T-Mobiles network not being able to handle all the new data over there lines or what not. Its been a full 2 days and I'm getting great data coverage. I'm getting my replacement HD2 tomorrow via UPS since I called T-Mobile and told them about the problem they said they would send me a new one. What should I do now. Its such a pain to have to set up my phone the way I like it but then again I dont want to risk having another data problem.

Dude, you are having some bad luck!
My phone is perfect. Well, it could use a keyboard, but otherwise...
same problem
I am have same problem..t-mobile 3g sucks i guess
It appears to be a common problems with HD2 users on the other side.

I was on the phone with T-mobile a few hours ago for an hour because my data connection would randomly drop. When I try to click it to turn it on, it would make me start a new data connection, wtf?
If I turn my phoen off and back on, it wouldn't even connect, with anything. The guy at T-mobile made me do a hard reset. My connection is fine now, but this was a hassle. I also notice Im not getting any better 3G service (as he said he update my network with better coverage).
I have the same problem with my phone. I have to constantly turn the data off and back on to get connection.
Both of my phones are doing it. They were both replaced recently too. Wish I could vote twice.
same here even if i have a full 3g bar data wont stay stable
No issues here.
been reading and stuff and more than half of the people with an HD2 have this BUT THERE IS A FIX search for it just like I DID

That's great for you if you have a problem lol...I didn't when I was on stock. Glad to be on Elegancia now...pretty good s***.
No issues here. Bayarea.
The other day, I was in the Dade County Fair in Miami and my cell phone completely lost all connection (not just data, but cell signal as well). It would randomly come up again for a few seconds before dropping. I soft/hard reset, took the battery out for a few minutes... nothing seemed to work, so I called TMO USA the day after to see if maybe I was in the middle of an outage, but nothing and the guy from tech support couldn't help either... I had better service with MetroPCS....
The data connection dropping happens the moment I set foot in my home. It switches out of 3G and the phone starts displaying Edge, which is a lie because there is no network connection at that time (try to update weather and it simply spits out a connection error). I'm gonna try to flash something else and see if that works (I am on stock right now). If I cannot get this solved by the end of this week. I am switching to Sprint and getting myself a TP2 (since I need SIM card capability in my phone).
I did notice one strange thing though. I used CleanRAM (level 3 option) at one point at home when I was with the faulty Edge, and it switched back to full 3G. So, at this point, I am starting to believe that TMO put something in the stock rom that either hinders, or makes the connection lousy...
I guess I put away my ORD for as long as I could with this phone
To put it lightly, T-Mobile plan sucks in my area, I had to switch to AT&T ever since then I havent lost any data connections.
Although I just moved to EnergyROM the other day since I just like that ROM since I used to use it on my Touch Pro. I never had data issues with the Stock ROM. Only time I had a data issue is when there was an outtage in my area and then even the phone didn't work.
I could not get my data connection to stay on more than a few minutes at a time until I loaded up HD2Tweaks. Since then, it's been running perfectly.
It's odd...however, if your phone's only problem is just switching between Edge and 3G try setting the phone to only run on 3G...under Settings->Wireless Controls->Phone->Baseband->WCDMA...
If your phone is cutting out...that sucks lol...not a whole lot I can think of except for the fact that the laws of physics apply in this case...the higher a frequency is, the farther it travels with less energy but the less it penetrates the environment around it. This is in part caused by higher frequency waves becoming extremely tiny, with over 1900mhz having waves that are smaller than a drop of water.
AT&T 3G uses 850mhz and 1900mhz for their 3G. Its lower frequencies don't travel as far, but they have more towers to make up for coverage area and the signal will penetrate.
T-Mobile 3G is 1700mhz/2100mhz meaning that the slightly higher range, while seemingly insignificant, when coupled with less towers, will cause the far end of the signal range to have too great a degradation of power, and not enough penetration to be viable.
Along with this is the fact that many government agencies still operate on the frequencies that T-Mobile purchased, due to not having a backup for their systems. Enough power generated within a frequency range will raise the noise floor enough that your phone's signal will get cut off. Sounds crazy, but it does happen quite often. You ever hear static on your radio? Analog is great in that you can lose data and still function. So government radio's are perfectly okay with a little bit of background noise.
However, signals that broadcast an analog translation of a 1's and 0's, function like a digital connection. When packets of information are lost in significant quantities, or in this case they are known are "frames", your phone cuts out.
Signal interference is becoming more and more of a problem in the cellular world. Satellite communications have had to deal with this problem for years. Only now are enough cell phones being packed into a single area for the noise floor to rise in significant quantities.
Just my $.02

for those who fix the problem can you post how you guys did it. i tried changing data to just 3g didn't work changing to voicestream it didnt work
I'm using HD2 since 25 march. Stock room. So far no problems.

HD2 Handset or 3G Blackspot?

Right. You might remember I had connection issues with the HD2. I sent it off for repair, and it came back, but now displaying "3G+" at the top. This was super fast and everything was working fine. Now, all of a sudden it has gone back to 3G that is REALLY slow! Now, I see other people are having this problem. According to Vodafone, I am in a 3G blackspot and there is nothing I can do. If this was the case, I would never receive 3G+ in the first place, which they just ignore when I ask them about it. Could it possibly be the phone? I personally think Vodafone are just messing me around
Only 1 view? Any reply would be appreciated, this is an ongoing problem for me...
Edited : Was being a fool
Just because people look at it it doesn't mean they are going to have an answer i have seen some threads on here go unanswered for the best part of the day until someone comes on-line that actually has an answer, so just give it time, not every member knows what everybody else knows, that's why its a forum for people to club together and help each other out.
rant over
Oh ok, I'm sorry
Ok, so now Vodafone are ignoring me, which is just great (pfft). I would appreciate ANY help if there are any tips as to any procedures I could undertake. The HSDPA I was receiving just cut out the other night, and won't budge from 3G any more, not even to G or E, which is kinda annoying.
Have you tried it in a different area? You'll not get HSDPA coverage everywhere - that's normal. The way you're talking, seems like you're just sitting in your house testing it.
Of course I've tested it elsewhere. What you need to understand is though, I was receiving HSDPA full in my house for a good few days after I got the phone back from repair, now its just gone. All of a sudden, gone. I try doing the network selection process again, and the 3G+ flickers for a millisecond at the most, and then disappears. I don't know why this is happening, I used to get brilliant HSDPA connection wherever I went in Preston
Just to give you guys a glimpse of EXACTLY how bad the connection is, I ran a speed test on my phone via speedtest.net. Here are the results:

There is DEFINITELY something wrong here, but what could it be?

Just to give you guys a glimpse of EXACTLY how bad the connection is, I ran a speed test on my phone via speedtest.net. Here are the results:

What is wrong? that you're getting as-expected 3G speed (.38mbps is the equivalent of 384kbps 3G standard) or the fact that you're getting a 3G+ symbol but are only getting 3G speed? Just because it's showing 3G+ (im assuming that it's similar to HSPA) doesnt mean you're at the optimal cell distance to receive it. It may be VERY POOR in your case, so it bounce you down to 3G.
That's the thing, its not poor in my area. I mean, I don't think even standard 3G is as slow as I'm experiencing. A 12 second YouTube video taking a minute to buffer? www.google.com taking a LONG time to load, there's something wrong man. I feel like just selling this phone and getting a BB or something, I know the connectivity will be strong with that.

How do you verify? Do you have another vodafone nearby that you can test out?
That's the annoying thing, I can't test out my SIM in another smartphone, as this is the only one I have. I have however tried another SIM in my phone and there is the same problem. This is the reply I get from Vodafone eForum:
Hi Faz20,
If it was a site fault that was to blame for this before, then it's highly likely to be the same sort of problem again. Issues like this are rarely ever the fault of the handset.
I have checked the postcode listed in your profile, and can see there are three possible HSDPA sites around you, none of which are showing any open faults at this moment, so we'll need to raise a case to our Faults Team for this to be investigated further.
I've emailed you so that we can start this process off
Jon
eForum Team
What is annoying me is that they keep ignoring me when I say I was experiencing fine internet connection with smooth speeds, and it just suddenly cut out. They just change the subject ALL the time when I mention it :angry:
One more to remember: you have to consider the speed AND QoS as well.
Try another site, I'd google for visualvare my speed.
If you have poor quality of service (you have veeeery long ping) that means: your phone tries to download.. then waits.. then tries again.. and some packets are lost.... so tries again... and so on.
1699ms ping is quite a lot I imagine? As my puter is only like 0.6ms, but surely the phone can't have that big a difference. Is there anything I could do to lower the ping, I don't want to flash and cooked ROM's atm as I am very inexperienced and don't want to void the warranty.

Then you're simply in a 3G blackspot. I know it's disheartening for having an HD2 and stuck with ****ty data coverage, but that's what seem to be the problem right now. You have a seriously high ping coupled that with slow transfer speed would only dictate that you're not in an ideal area where 3G coverage is plentiful.
How would that explain that I was receiving fine connection speeds before? This is where my hair is falling out

Maybe you're hallucinating that you had fast connection before? Maybe Vodafone thought that your area doesn't deserve the bandwidth and thus prioritizing the 3G speed for other, more robust, cities? Or maybe radioactive termites have run amok on the cell tower, causing you to not get fast 3G speed?
Who knows...
Nah, I can assure you I wasn't hallucinating, I stay away from the Magic Mushrooms
I just think Vodafone are a bag of s*it. All my friends with the same phone on O2, Orange are receiving HSDPA all the time. Its stupid
I'm gonna phone up Vodafone today and kinda go mad at them. The last time I phone they "escalated" the connection, maybe the reason why I was getting HSDPA all the time, wherever I went. Now suddenly its gone again. Quick question for you guys, when your phone is on 3G Full bars, how is the speeds. Are they quick and rapid? Do Internet pages load quickly? etc. etc.
Ok, so what do I get told when I ring up Vodafone. I have bad 3G coverage in my area (blatant lie). When I ask how do I resolve this? Buy Vodafone Sure Signal, £50 one off payment or £5 a month. Great way to resolve a problem, try to sell me something else, another one of Vodafone's probably bullsh*t products. Its so frustrating, having to live with a stupid network provider with such a beautiful phone!

frustrated with hd2 losing signal

I have trying to use the HD2 over the last 3 days and getting real problems with intermittent signal loss.
I know i have low signal from the mobile operator in some parts of my home but that has never been a problem with other HTC phones i used before. If the signal was too weak it would just drop out but come back if i moved a bit.
With the HD2 once the signal indicator turns red it stays that way even if i move to a strong signal area.
The weird thing is sometimes i would leave the phone sitting in one place with four bars and then minutes later it would show up with no signal and i can't receive calls.
Even stranger is that in all these cases where there is no apparent signal, all i need to do is press the send button to try making a call and the signal "magically" re-appears and all is fine. I've tried at least four differnt radios as well as the energy ROM ... no change.
Any ideas ? this is reaallly frustrating!!!!!!
do the problems resemble what I experienced here?:

change radio ROM, well experiment with several of them by trial and error (read the sticky/tutorial first).
OR
buy an indoor signal booster.
Well, regardless of the radio version ive had really odd intermitant service.
the best way ive found to help this is turn off 3G / HSDPA
Doing this forces the device to remain on GPRS, it means the battery lasts a hell of a lot longer and it doent drop the connection every time the device feels like trying to connect with HSDPA or drops it for no apparent reason.

it seem that you were losing data connection .... i'm a lot worse off ... i lose data AND voice .. all connectivity ... so i don't receive calls
as i said the weird thing is as soon as press send to initiate a call,cthe signal bars come back and everything works fine!!
as i said, stop 3G from working, when switching between the two due to what ever reason the HD2 decides to drop it will kill your connection, voice and all until it switches back. there is an issue with 3G and im wondering if its everyone or just folk using TMOUS radio and thus recieving the extra RAM
To disable 3G/HSDPA to test,
Open Comm Manager and click on Phone (not the on/off switch) to go to phone options. Scroll to bottom and select BAND. Switch network type from Auto to GSM.
3G/HSDPA is only needed for internet surfing. Time, weather, stock updates and email downloads don't really benefit from it. So turning it off this way will make these type data connections go through the EDGE network which is plenty fast enough for it. When you need to surf the net, go back and switch it to Auto and you will get 3G or faster speeds for that.

hello im having the same problem..no voice or data i push my send button an then i get signal,my wife has a hd7 and my son has a hd2 they will have 3 to 4 bars and i show no signal.push talk and i get 1 to 2 bars.
have you found a fix?
You could always try a signal booster on eBay for like 5...

If its just 3G then its probable just T-Mobile or then again a Hardware/Firmware issue
try a different ROM, Radio
I have this same issue I running a T-Mobile USA (using radio 2.12 but then again it was doing it on 2.15 as well) and it just drops all connectivity and says no service I have to search the network again.
My phone is unlocked I don't know if that might have anything to do with it as well
I've had this problem on my HD2 since i got it.
Edge (E), works but slow as all get out. 2-4s ping times or time outs. 3G (and when i say 3G i mean when it says 3G in the status bar) doesn't work at all. HSDPA (H) works great, WHEN it stays that way, which it doesn't.
It can switch between 3G to H every 10 seconds.
And i'm using it for tethering primarily, which makes working painful. Lose your VPN and SSH sessions constantly. Some days it's ok. But most, horrible. btw, i'm in the Denver area.
I've tried stock roms and custom roms (primarily Energy). All radios. Nothing fixes it!
This is the only thing I don't like about my HD2 and/or t-mobile. And it's a whopper. I'm almost ready to get another phone or carrier, depending on what's causing this.

I have 4 HD2's with one having the problem you describe and have come to the conclusion it's a hardware issue. Probably a cold solder joint on the antenna lead.
In WinMo or Android the signal bars jump all over the place but the signal level in 'about phone' shows a constant signal even though the bars show nothing. I don't drop to many calls but miss more than a few incoming. I travel for 5-8 hrs in the same area everyday and very familiar of good and bad areas of reception. I have tried stock/cooked ROM's/Radio's with no noticeable difference.
I'll probably send mine in to HTC to be looked at.

[Q] mobile network connection failed on wcdma, but works on gsm only

hey all, i've been a longtime lurker of the xda forums and always appreciated the fantastic work everyone here does. i searched the forums for this problem but saw many discontinued threads with no answer which is why I'm bringing it up (apologies if i wasn't thorough enough) .I was running the latest iced glacier rom 1.1.6, i checked that thread but found nobody with the same problem, making me think it was most likely my mistake and not a glitch in the rom. i was running wifi all day so i didn't notice until tonight that i can't connect to the mobile network when set at the "auto gsm/wcdma" and "wcdma only" setting, and only connects to "gsm only". its only when i connect to "gsm only", turn on mobile network and then go to the settings and select "auto gsm/wcdma" that it will connect me to 3g data . everything else gets me a "connection failed". I punched in the APN to no avail. I'm glad i found the way around the problem but I'd rather not have the problem at all. i did a factory reset and put the APN again to make sure, but still the same problem. does anyone have some insight into this problem and can help me? much appreciated
tl;dr HDSPA connection attempts fail, only Edge works

Hmm weird. Same thing happened to me today but it happened to me a different way. I was running CM Nightlys Build #3 and decided to do a nandroid that was from 2.x. After doing that Nandroid i ended up getting into a bootloop. So i figure okay, i'll just wipe everything and reflash CM since it was in my internal SD. Everything booted up fine but then i had no access to my data. Couldnt even connect to wifi. I then tried to go back to stock by installing the Pd5.img thats in the develop. forum and it returned me back to stock fine. Now my Wifi works but the data on my phone is still broken. I try to check and uncheck the Mobile Network and it just keeps saying Connection Failed. What do i do?

This is weird but I must live between several towers because I have a solid 2-3 bar H signal but my phone will drop to E aka edge at times and phone download speed takes a nose dive.... however if I change phone settings to connect only to wcdma the speed stays constant and super fast...
I have only noticed this happening at my home and no place else....
Anyone else ran into this?!

aloha guys. well i woke up today and my mobile data could connect fine. i'm thinking since i was messing around with my phone at the time of this supposed outtage, it tricked me into thinking i messed something up. 651stp, did your problem go away as well? i feel kinda dumb now cuz i wiped my phone clean, s-on and everything, and it still wasnt working and give it a night of sleep and now its fixed but i'm gonna have to set my phone up again. ah well...

yes, my phone connected to data today LOL. damn that sux, i stayed up an extra 3 hours till 8am when i only usually stay up till 5am. almost made me late for work lol. data connects fine now but s is still on. maybe i'll re-root and then retry it to take it off. i need to return the phone and buy it elsewhere for cheaper.
I have been having the same problems even after changing out the phone. I believe it to be a problem with the software that runs the radio or the radio itself. It switches to different bands on it's own. I hope someone can address this with HTC or T-Mobile or both...
Why do you all quote the entire previous posts? It's obvious who you're replying to, so what's the point of that?
Anyway, I have somewhat of a similar problem, but haven't spent time trying to track the cause.. It might be related to wifi or maybe not, but at some random time after turning off my wifi, I will lose complete mobile network connectivity. No data will download or upload at all, until I reset my phone which seems to be the only way of fixing the problem.
I'm running Iced Glacier 1.1.5.1

You know, now that you mention it, I dont know why.
Just kidding! Dont beat me up!
Anyways, as far as my phone goes, its gone all day with no problem. Re rooted and restored so im 100. Never doubt that your local t mobile signal could be going through some maintenance.
Sent from my HTC Glacier using XDA App
Location, Mobile Networks, GSM vs WCDMA, etc.
I was about to post a new topic on this, but the nifty little Ajax monkey robot showed me this thread matched my keywords.
So I'm one of those d-bags that uses Facebook Places (Check-in). Not a lot and I don't frickin' check-in everywhere I go. I hate it when people do that. (Thanks for letting all of Facebook know you're not at home, so we can go break-in to your house.) I do use it though, as well as Yelp.
While I'm out, I'll go to check-in and it just spins its wheels - i.e. no Places load. I can be outside, clear sky and have GPS enabled and it still can't find my location. I noticed the same with Yelp, but Yelp actually errors out and tells me it cannot determine my location and prompts to go to my Location settings. Even with GPS enabled, Yelp still cannot determine my location. I noticed this here in Orlando/Longwood, FL and all the way down and through Ft. Lauderdale.
Obviously, if I enable WiFi my location can be determined instantly - e.g. Facebook Places finds it, Yelp finds it, etc. I'm not on WiFi all the time, so I don't really want to only be able to check-in at home.
I checked my APN and it has't been touched, it's at the default. I am on Ice Glacier, so I was willing to believe something could be different, but APN is correct. I also checked my stock ROM (Nandroid backup) AND my fiancee's phone, which is running stock (rooted).
I'm thinking it's got to be something to do with how my/our device(s) are registered on the network. So I look at the Network Mode and notice the default on my/my fiancee's phone is GSM/WCDMA Auto.
Just for giggles, I decided to knock it down to GSM Only. The radio restarts and then no H comes back - only Edge. I'm not just talking about the icon, I'm talking about the actual speed. Here's the cool part - once I went down to Edge (forced by being on GSM Only), guess what? Locations work perfectly now. Albeit a bit slower, but Facebook Places loads Check-ins immediately and Yelp is able to find my location now.
If I switch back to the original setting, the radio restarts, I get H back and for anywhere between a few minutes to a few hours, my location can be found. After a bit of time, I'm back to the same boat - location cannot be determined by mobile network.
I tried this on my ROM, my stock ROM and my fiancee's MT4G running stock - I can reproduce this 100% of the time.
I figured next, I'd try WCDMA Only...

To my surprise, location works perfectly now, 100% of the time. I switched to WCDMA Only last night and I have been able to use any/all apps that determine location by mobile network.
I will record a video of this, as again, it is 100% reproducible on multiple MT4G's and various ROMs. Our signal strength and network speeds in this area are amazing (Orlando/Longwood, FL). I consistently get 7-9 mbps down and never go below 6. My battery life is fantastic, as my radio is never switching between network types (note: In other cities, like in south Florida, battery can die super quickly because it's constantly jumping from Edge to H and back again).
Even better, when I use the Speedtest app, my server list no longer only has Atlanta or Washington, D.C. as my closest servers. I now have a ton of servers here in Florida, out by the coast, etc.
So there's my brain dump for now. I am not saying I have a fix, but I am saying there is definitely an issue w/ how these devices are registered on the network. I'm not saying I should be on WCDMA Only either, but I can say that in our area, my connection is perfect and now I have no issues with location via mobile network.
What the heck could the issue be? Why wouldn't the device be able to be found on the network when on GSM/WCDMA Auto? Edge does location flawlessly (when forced via GSM Only) and WCDMA Only does location flawlessly as well.
I'll do my best to record the video this weekend and show this top to bottom, but I figured I'd share what I could to see if A) this would help anyone with this issue and B) to see if anyone could shed any light on all of this.
Bump,
Did you resolve the issue? I'm having the same problem.
mine works fine on cm7 and set to GSM/WCDMA Auto. It might be the towers in the area, call TMO support and tell them your problem and your fix. They'll send a tech out there to check the tower
That's exactly what I was thinking, but I wanted to see others' opinions.
I'll let ya know what TMO says...
