Making calls unreliable on 3G (UMTS/HSDPA) while on AT&T - myTouch 3G, Magic General

I was thinking of posting this in the general section but posting it here seemed more appropriate as I think the issue at hand is of a more technical nature. If this is not the case I apologize in advance.
I recently purchased a Black HTC Magic (Rogers branding) for use on the AT&T network here in the states. Since then I have had a very difficult time initiating calls while connected via 3G (UMTS/HSDPA). Even in high or low signal situations.
Unfortunately there doesn't seem to be any consistency to my ability to make a call while on 3G. At times 5/5 calls would be successful and other times 1/5 calls are successful (the latter being true more often than not).
Suspecting there was some issue with my device being on 3G I forced my device to use 2G (EDGE) connections only. At which point my reliability issues go away completely (from what I can tell).
I don't experience any strange issues with using my data connection while on 3G/2G so it seems to be specific to voice.
Another interesting thing to note is while trying to initiate a call with the Google Voice application on 3G, I experience the same call initiation issues as mentioned above. Google Voice works as expected while on 2G.
I experience these issues on the original shipping Roger's ROM, as well as all the other 3rd party ROMS (HoFo, Cyanogen, etc...)
Here is information about my device from fastboot...

Is it possible that my SIM card may be causing issues?
Anyone else with a North American Magic experiencing issues on AT&T? I appreciate any help you guys could provide.

your phone is ok
perhaps you might have heard... iphone great phone...AT&T absolute **** network
with dropped calls, and constant diverts to voice mail. dont sweat it. its AT&T not
your mobile.

I would have to agree that it's probably the network, although I might be wrong. I also have a Rogers Magic running on AT&T in Arizona, and I have this issue as well, but not nearly as frequently as you do. This same problem used to happen from time to time with my HTC Fuze and my BlackBerry Curve.

I've had a variety of different devices on the AT&T network (Northeast/Washington, D.C) and although yes I have experienced AT&T's wonderful network. What I'm experiencing just doesn't seem right. Makes me wonder if it's my SIM or particular build....

Moved into general discussion forum as not related to android development

if you are not using a newer sim card i would start by changing that. i was using an older 3g sim which i have used with many phones and i found that by changing to a brand new sim the few connectivity issues i had have gone away

which ROM?
Just a question, but which ROM is everyone here using? I, too, experience the random inability to make phone calls over HSDPA. I was told by an at&t rep in-store today that the Rogers Magic does not 'show up' in their system as 3g capable. Pure bs is what I think, but lets rule out software, yes?

If it is not your sim card then it is most likely your network.

Calls over 3G/HSDPA is fine on my Magic and was also fine on my Nokia N79 using the same Cingular SIM card that I have. However, making outgoing Google Voice calls over 3G/HSDPA is a no go.

Yeah...making calls was fine on my Unlocked Touch Diamond, too...but it's NOT on the Magic (32a).
SO...I'd just have to guess that it's *probably* not the SIM card.
I was told (via an exceptionally helpful phone rep) that the "voice 3g" in my area is not very good, but that the "data 3g" is much better. Which (she says) is why I have trouble making phone calls, but that data works fine.
I don't think so...but without *that* answer, I'm left with the AT&T stock "well, we don't support *unlocked* phones, sir, we can't guarantee that they'll work with our network".
ARRRRRGH! REALLY?! SO, phones with the same chipset, using the same technology won't have the same results?
PLEASE, FCC, INVESTIGATE THIS B.S!

Hey radikaled, I have some new developments with GV and outgoing calls. If I set the GV call options to "ask for each call" the issue of calling over 3G appears to be alleviated somewhat. Basically, when initiating a call, you will be prompted on whether you'd like to make the call via GV or not. At this point, wait a few seconds at this prompt and then choose GV. So far the call has successfully connected 100% of the time.
It appears that the data connection is too slow to establish fully over 3G, therefore, the call fails if you don't wait the few seconds before choosing to call via GV.
Let me know if this works for you.

I too had issues with my ROgers Magic unlocked on ATT. When I first got it I used the original ROM and then the HoFo ROM. Both had similar issues with dropping calls when switching from EDGE to 3G and back. I also dropped more calls than normal.
I recently switched to Cyanogens ROM and new radio. I have not had any issues since and then. Calls and switching is very stable. Also the clarity and volume is also much better. Just my experience. Very pleased with this phone on ATT now.

Thanks for sharing your experience. May give CM ROM a shot.

Good read.
Nice post. Interesting topic.
I tried to send several other users your way...I'm sure they eventually checked this out. I've come across this issue with some other folks recently too.
Best of luck though.

Me TOO!
I also have a similar problem. When connected with HSDPA, about one third of the calls I make fail immediately, even with full signal strength. I then wait a few seconds and dial again, and it works. I actually am using the sim card from a previous nokia POS phone I had from two years ago; the ATT people just took it out of the previous crap phone and put it into my poor fuze. How much does a new SIM card cost? Can I get a new SIM card without att bothering me about not having the stock rom? I'm using Da_G's clean fuze 23008 winmo 6.5 with the 1.12.25.19 radio. I live in the Youngstown, Ohio area (between cleveland and pittsburgh), so cell reception on any network is pretty bad, but it seems the ATT/cingular network around here is particularily bad. Any ideas?

Not receiving phone calls?

Hello all,
I have had my X1 for about a month, and it seems I've come across a problem that defeats the purpose of a phone. I can't seem to receive calls for some reason...recently my friends and family have been telling me they have tried to call me but it just ends up going to my voice mail. I just tell them I was probably on the phone with someone at that time, or my phone was off. Only today did my friend call me to find me in a parking lot that I finally realize its my phone. So I attempted to call myself with my homephone, and tada! it went straight to voicemail. I don't even get any sign of a missed call.. Did anybody else getting this problem? I did a soft reset and it seem to fix the problem. It has probably happened within the past 2 weeks..I have the generic UK rom so I'm still waiting for the official R2A one. It would be great if someone could explain how to prevent this problem from happening.
not that i have a problem with my x1a, mostly because i rarely get calls and rarely use it but i have another phone that would have a problem that you describe.
i think it was due to the phone switching between 3g and edge signal. i work in the ship yard and the steel walls around the ship interfere with my signal and my phone would switch back and forth between getting the best reception (3g and edge).
well anyways, i think the switching back and forth would somehow screw my phone up and i wouldnt get any calls after getting off work.
my brother who also works at our shipyard and carpools with me would try to call me up to ask me if i was getting off in time but i wouldnt know that he had been trying to call me untill we meet up. he tells me that he has been trying to call me and so as were walking back to the car, i asked him to call me to see if my phone is working.
sure enough, my phone doesnt work untill i turned it off and then turned it back on. so if your in an area with poor 3g reception, maybe that could be causing your problem.
my old phone was an old lg cu500. thats my beater phone and since i dont use it for browsing the internet anymore, i set it and leave to use edge. it gets a stronger signal than 3g but if i do need to use 3g, i just go to my phone settings and set it back to use both signals. for some reason, i almost love that beater phone more than my xperia. mainly because its small, compact and i dont have to worry about scratching or damaging it anymore.
hmm, that is rather interesting...however my service provider's 3g frequency band is not compatible with the x1. I also don't have an internet service type of plan with my phone.
However just going to my settings, I noticed that my phone was set up to attempt to connect to the internet via HSDPA. I'm going to disable it and see what happens.
if you dont have 3g or hsdpa connection, then i would set your phone to use only gsm.
I also miss most of my calls but my problems is other some times it rings and some times it doesnt. Anybody know how to fix this?.
I have seen these problems with another PDA, in that case it seemed to be related with the PDA radio at the beggining, but even if that is one of the probable causes, there are another two to be considered.
The first one is the sim module, I own the same sim since 6 years ago, and this sim was programed specifically for the symbian phones of those years, it is in fact unable to send/receive any MMS with a PDA.
The other PDA I'm talking about is an Universal, the same phone worked ok with my sim and failed to receive many calls (even if the covering of this phone company was "better") -in the same place- with the universal, We first suspected a broken sim, but using this sim in a old gsm phone, it worked just fine.
Also, the cell companies, tend to "abuse" of their position and then to "seed" the phones with applications that do use the phone automatically, these programs are made mainly for symbian phones.
Remember also that the cell networks are exactly that, computer networks, and sometimes their databases are not perfectly compatible with all the possible variations of slightly different phones, in this case, PDAs are the least common type of phone.
So, try your phones with other (another cell company) sim, try using the sim with old phones, etc.
hope this helps.

Rogers 3G network

Hey guys, I just wanted to see if anyone else is having a longer waiting period with the Rogers 3G network lately or if it is just me. I've been noticing that my phone has slowed down quite a bit when browsing the internet or using an application that requires data on the 3G network. My wi-fi is fine, just the 3G. It takes between 45 secs to 1 minute to retreive the information. I had called Rogers and asked them to reset or refresh or whatever they do down there, but didn't seem to help.
Now if it is just my phone, maybe it is some application that is using up the processor or data, but I don't have that many applications running in the background other than weatherbug that constantly uses data.
Any suggestions would be helpful.
Thanks
What happens if you run a speedtest? the app by Xtremelabs is good.
no issue here. i use mine on a daily basis between pickering and mississauga, and as long as i have at least 2 bars of signal strength my magic is very fast over 3g
Thanks guys for the quick response. I think I found the problem. I had called Rogers support again and they said that it is due to my sim card being a 2G one. I need to replace it with a 3G. Hopefully that will fix the problem.
Thanks
I too have been having internet/email issues since last Thursday using my Treo 750. The symbol toggles between 3G and H and usually does nothing but comes back with an error message saying something like 'cannot find this page...'. I travel between Oakville and Concord every day with the same issues. The phone worked perfectly in Brantford last night...so I don't think it's a hardware issue. The tech support guy grabbed a treo and tried and was able to connect on EDGE....not 3G.
I tried my sim card in my sons Motorola Risr and it works perfectly....on EDGE. They tech support guy said they were having issues with 3G last Thurs/Friday, so I'm wondering if whatever they did last week is affecting some older phone models (I've had mine for 1 1/2 years now). Not sure if I can (or if I want to) configure my treo to connect via EDGE instead of 3G...
Anyone having the same problem?
Very odd indeed. I got my new sim card but still doesn't fix my problem. At least I'm not the only one experiencing the same problem. As far as I know, the 3G and H symbol are he same thing according to rogers tech guy, correct me if I am wrong. I'm going to call again today to see if I come up with anything.
Just got off the phone with Tech Support again. They are sending me a new Sim Card, but from the sounds of it, that's probably not going to fix the problem. He WAS going to do a free hardware swap until he discovered the phone is out of warranty. Then it was basically "oh gee, three year contract, one year warranty...tough luck".
Yep, the G and H are the same thing. Since mine is switching back and forth, he said the phone is hunting for a signal.
When I asked why the phone worked perfectly in another city he couldn't give me a good answer. I have to go back to Brantford tonight, so I'll get a chance to repeat the experiment.
Listen folks. It has nothing to do with your SIM card, nor your phone. The reps at rogers, I for one, ASSUME it could be the sim card, but really, most of the reps cannot differentiate an incompatible SIM with a compatible one, so they send you out a new one anyways, just to get you off the phone because they really don't know what the cause is and they have no hands on the status of the networks and network problems other than what is posted in library by the actual IT department, which do not directly communicate with the centers.
To sum it up. Rogers 3G network is garbage! and that DNS issue is not isolated to the metro area, it's here too in Newfoundland. DNS resolution is extremely slow, even with OpenDNS, which means it's their switches that are garbage and most likely being bogged down. Rogers thinks they had solved the problem by throttling the 3G bandwidth to ~3Mbit and the upstream to less than 150K, (My assumption), however, that isn't working.
From my guess is that the request is sent to Rogers networks, which cache that request then caches the pages and sends it to your device, making it appear you have a fast connection.
Anyways, sometimes I find the EDGE network a lot faster..especially in the DNS resolution area.
"It has nothing to do with your SIM card, nor your phone"
My feeling exactly. It just seems a little too coincidental that everything was just fine until they had a network "issue" late last week.
So, being a mechanical guy with very little knowledge of how a these things actually work, is there a way for me force the treo750 to use the EDGE network?
Never mind, I got a hold of a guy at Rogers who seemed to know his stuff. He told me to get the latest OS from Palm and then how to go in and set it up for EDGE. We'll see how that works.

I love ripping on Rogers for being crap, they are, but the network is downtown Toronto is far from crap. And it is not throttled. I have had repeated speedtests reach 3900kb/s with the average around 3100kb/s. Thats not too bad considering the crap they put up with in the states on AT&T.

True, compared to the 3G in the U.S I would agree that Rogers has an edge, 3G here in Newfoundland is still in it's infancy, well still is everywhere. We just got 3G last winter I believe.
what newfoundland has 3G?
now hell really has frozen over (ha)

New theory for signal drop/loss of data and dropped calls

So after reading mostly every post I could find on the net regarding the Vibrant and its signal bar issues, it's pretty apparent that most everyone experiences the signal indicator dropping when the phone is held a certain way, however this only seems to affect some people's data throughput and voice service. I have read a couple of people that do not have these dropped bars, but those posts are few and far between, so I think it is safe to assume that there is a definite bug with at least the way the phone displays signal.
I have a new theory. Now, I'm no expert with cellular technology, so this may, and probably is, totally wrong. But as I was unboxing the phone, I noticed that this was the first time I got a new SIM card with any T-Mobile phone since my first, the original T-Mobile PocketPC Phone Edition, in what was that, 2002? 2003? Every other upgraded handset I've ever owned didn't come with one and it was assumed you just pop it out of your previous phone and you were good to go. Have SIM cards changed at all the way they handle these newer networks, especially HSDPA and HSPA+, or is it still all of the same? My new SIM doesn't work because I believe it isn't registered to my account on the network, so I am using the old one. It is a dumb theory I know, but its worth thinking about. Someone who is better educated will probably school my noobness, but I just found it interesting that this is the first phone on T-Mobile that can take advantage of these newer networks for both voice and data, and also the first one to include a brand-spanking new SIM card, in my experience anyway.
If this theory is totally stupid, does anyone else have any other theories?
Also received a new SIM card, unasked for. No idea if and how this could affect signal, though.
New sim cards should have basically no input on your reception. It just tells your phone which signal ranges to use. Thats it. Also contact storage.
Meanwhile you have to seriously hamfist your phone to cause anything, none of which would result in a dropped call nor a stopped data transfer.
Please stop the false hype. Vibrant won't drop calls like the iphone would.
Sent from my SGH-T959 using XDA App
The old sim cards can only register on the network some 90k times or somesuch before they go bad. The swaps between 2g + 3g networks are causing lots to go bad faster. The new sim cards don't go bad at that point. That is the only difference. You will know if it's gone bad if you're getting "sos emergency calls" or "unable to register," but it shouldn't have any effect on loss of data/signal temporarily. It will simply no longer connect at all, period.
You sure about that magic 90k number? Got a link to back it up?
I would have a year tops if that were even true.

No links, sorry. I'm in cust care for t-mobile, and it was in one of our updates explaining why exactly we were getting these mysterious new sim card codes in the system when there was no other noticable changes to the sims. No increase in storage for contacts, or anything else, we were all kinda "huh"
Edit:After searching around for a relevant link I stumbled upon the one below stating that it might cause similar problems, although I've yet to see that being related in any of the troubleshooting I've done. At least the specifically UICC problem.
forums.t-mobile.com/t5/myTouch-3G-Slide/cannot-make-calls-losing-signal-apps-force-closing-Problems/m-p/416847
Sim cards can cause some problems for people. I can safely say that even with the weakest of signals MY Vibrant will xfer data. I have the screen shots to prove it. I've yet to drop a call. The only thing I have a problem with is the GPS and the occasional pausing. I wish we could get some information from T-Mobile and Samsung about this matter and when they plan on fixing it. I see they're working on it by "leaking" betas to i9000 handsets. They need to fix the bars too because it's more annoying than anything. Otherwise I love the phone. GPS/zero bars will do for now but I want it to match the rest of the phone. The phone has no problem seeing up to 14 sats (only on stock settings) but will not connect to them.
My sim card is the one that came with the phone. Some networks have a special 3G authentication based on your sim but I don't believe T-Mobile is one of the carriers that use this.
I am using my old sim card and I still get attenuation when I cover the bottom of the phone. I have never lost a call due to it so I have always figured that it is just faulty reporting of the signal. In my house, where I get pretty bad service, I can make it show no bars but I can still receive a call (I got one while I was playing with it by odd coincidence)

Not receiving incoming calls when 2G/3G etc connected

The other day one of my friends told me that when he rings my phone lately (since I've started using Android) it always diverts to my voicemail. I did a bit of testing, and figured out that is seems to be happening when 2G/3G data connection is active. Has anyone else had this problem, and can a few people test this out?
I've tested this with 2 radios:
Leo_RADIO_2.12.50.02_2
Leo_RADIO_2.07.51.22_2
and 2 android builds:
30.08.2010¦ ?shubCRAFT 1.5?CM6 Final?¦ ?Kernel: ElBartoME 2.6.32.9 #1? ¦
New Nexus One Android 2.2 Build FRG33 [ mccm v1](5.9.2010)
I have tested on WM and this problem isn't happening there. I am on O2 UK Post Pay.
I have this problem and it happens when my phone is sending/receiving data, not when the data connection is idle. It happens on WM, Android, and on my iPhone too. My provider says this is normal and nothing can be done.

Switching from 2.12 radio to 2.10 in my sig helped this a lot.
Sent from my HD2 mattc froyosense using XDA App
I gave 2.10 a go, but it seemed to make little difference for me.
I had the same problem with the 2.12 radio. I wouldn't get any calls from sprint users.
This is normal with GPRS aka 2G. It's like you go online with a modem and a phone line in the old days (dial-up). Even when you are trying to send a txt, and a call come in at the same time, the text sending will fail. This is very annoying.
not sure about 3G tho, some say that the 3G can handle data and calls at the same time.
I get this too, Plus when i recieve a call i cannot hear the caller for 10 seconds or so ? but the caller can hear me straight away ?
I did post this in the HD2 general thread but got no responce...
Have changed sim card as i was told this could be the issue but no luck also tried various radios/Builds inc android again with no luck..
Looks like were gonna have to live with it

GPRS/Edge does not necessarily allow simultaneous voice
Well I had no idea. I thought that one of the main advantages of GRPS/Edge was simultaneous voice and data, but I guess not. Apparently it is dependent one the cellular network configuration/capacity.
Here's an MSDN article related to it (not that I consider MS a reliable source of anything, but worth a read )
http://msdn.microsoft.com/en-us/library/bb416348.aspx
I had this exact problem. For me it started after using android on my HD2 then whenever i had my phone on UMTS i could call it with another phone and 4 times oout of 5 i would ring all the way to voicemail and never notify me. I first thought it was ATT but i tested my sibling's phone and it was fine, i even switched SIM cards. the problem seems to have gone away with my HD2 after two weeks however I ended up ordering a telus desire with ATT bands. Although now my HD2 reboots in android randomly whenever using UMTS data.

This is what I get as well, except the caller doesn’t hear me for 5 secs or so. I end having to say “hello” 3 times before they can actually hear anything and by that time they usually hang up. I’ve had this problem with WinMo as well, using Telstra on Rogers. It’s kind of annoying since I end up having to use daytime minutes to call them right back.
I found that some x.51.xx radios helped but Android as far as I know is only compatible with x.50.xx radios. So hopefully a new radio will help with this though I’m not really counting on it.
I thought I was going mad
I have the same problem but only just found out. I use my Google navigation a lot, but just discovered when I do that incoming calls are routed to voicemail. I have tried 3 different Radio's from the recommended Leo_RADIO_2.15.50.14 down to 12 and even 08 nothing seems to work.
I have also tried different ROM's from HD Desire to Gingerbread, again no difference.
Not sure if the problem existed on the SD ROM's but it is sertantly an issue on the NAND ROM's.
I am using RMNET as this is the only one that seems stable on O2 in the UK.
This problem is driving me crazy.
Someone else please HELP!!!!

Problems with i9000M

Hello,
I bought my phone brand new and I unlocked it myself using the method discovered here. Recently, I noticed that some incoming calls go directly to voice mail although I might have clear or even perfect reception. Since I live near the US boarder, switching to US providers solve this issue; I’m with FIDO and have an un-rooted stock ROM (2.1).
Thank you
no problems here in the Toronto area
not sure what you can do, it's tricky when i visit Niagara Falls, sometimes it switches to AT&T on its own (using old phones)
i'm sure Galaxy S will do the same thing like all other phones, i'll most likely just pick which ever signal is strongest
