G2 Data Connection - G2 and Desire Z General

Has anyone been having issues with the G2 Data? This morning and another morning this week my data failed, I tried going into airplane mode then restarting the phone completely still no signal and no cell signal either. My friend has a hacked and unlocked iPhone and his is working fine so I know its not a network issue with the towers... As well another co-worker has a myTouch 3g with no reported issues. Thankfully I have a wifi signal here at work.

That unlocked iPhone your buddy is using is EDGE only, obviously. That's going to give a better connection inside. Try running 2G only mode next time you get that issue.
I bet it was just a brief network outage in your area. It happens sometimes.

Not brief if it's a network outage... my connection is still gone... both my friends have theirs and one is on a myTouch 3g...

I do have occasional data connectivity issues, however, not that severe. Just your (what seems to be) typical "arrow stuck in the up position" issue.

Sounds like you have a problem then. I haven't experienced that on my G2 yet. My N1 forever had data connectivity issues.
Are you using the new simcard that possibly came with your G2? I have no idea if that makes a difference, but just asking...
Call T-Mobile and see what's up. Maybe they can refresh you on the network.
800-937-8997
Say "english" at the first prompt and "representative" at the next prompt to skip to a live person.
Good luck.

Thanks Sean.

Tmo has been having issues, there are several reports of this and all my demo phones are unable to get online(though regular signal is fine) I would call care to let them know you are having issues too, ask them to make a ticket and/or send an engineer

I had to exchange a couple until I got one with a solid 3G connection. Previous G2's had no connection or were in Edge 90% of the time.

Nothing wild here.
It seems to work as its supposed to.

Would love to see mine switch to 3G. Been on Edge 100% since I got it Tuesday. Advertised in a soled 3G area, but no luck. T-Mo CS politely told me I will love Edge. Will be switching to Sprint Epic if nothing changes in next few days.

Mine does that too. I have to restart it.
Wonder if the supposed OTA-vapor new radio will fix that.

I've been having data issues too, seems like it has to do with how my phone is held (HTC antennagate?) I hope the mythical OTA comes with a radio fix (if that is the cause) and/or a vorpal blade....

I have a ticket open with tmobile about my data issues.
I'll have my phone on the desk and it'll have 1 or 2 bars of H and then I'll pick it up and its goes to G then to E then to nothing. Its worse when I open the keyboard.
I love this phone so much I hope its just a software fix. Is the OTA going to have radio fixes?

Exact same problem here. It's so frustrating. I've already exchanged it once and spent an hour on the phone with tech support. If it keeps up, I don't know what I'm going to do.

I am not liking the data issues.... I love the phone besides.
Fixed with a soft reset but that has to change...

There are a bunch of us with signal issues. I live in Vegas where we have great HSPA+ coverage and Im still getting a lot of issues even with 3G, that I didnt have with my Nexus One.
Check out the thread on the T-Mobile Forums. (I cant post the link since Im new here )
My issues are simply the phone works one min then the next there is ZERO signal, if I dont move but restart the phone I have full signal again. Some times the signal comes back on its own then other times it doesnt and I have missed calls after the restart.
I bought my dad a G2 as well (upgraded him from his G1) for his birthday, and he is having similar issues. I went into my local t-mobile store and they replaced the sim card 2x now and that didnt help. What I did find that helps is that if you set it 2G mode the phones seems to work fine. This is a temp fix but its retarded that T-Mobile's fastest phone is being forced to run in 2G mode.
I hope someone on here can figure out the issue or t-mobile comes out with a OTA fix asap.

Wow, the rep just tried to tell me I live in an area that is only covered by edge. I asked why I've had 3g hooked on my phones for the past 2 years and why my girlfriends phone says 3g. She then said I was wrong and she didn't know why the last rep told me I was suppose to have 3g. She then directed me to the coverage map where I pointed out to her how wrong she was.
....and she's a PDA specialist.
What upset me was how she was trying to convince me I lived in an area where 3G was not available. Despite having had 3G at this location for years. I told her I'd just call back tomorrow.
Edit: She must be on drugs, I see that I'm back on 3G.

The rep on the T-Mobile forums is asking you to PM them your info:
Hi everybody!
If you are experiencing this, we would like to hear from you. Please send me a PM with a few details. The location information requested is particularly important.
(Do not post your private information here in public.)
1. Describe your signal indicators when things are working well. For example, "Full signal with an H."
2. Describe your signal indicators when you are experiencing the issues in question (No signal, one bar, E, G, etc).
3. Provide a location where you are experiencing issues (city, state, zip code)
•Are you aware of other T-Mobile phones experiencing or not experiencing these issues at the same location?
•Are you indoors or outdoors when you are experiencing the issues in question?
4. Provide a location where things are working well, if available. (city, state, zip code)
5. The T-Mobile phone number in question.
Thank you!

I've had prevalent connection issues as well. For me, turning off Bluetooth and WiFi fixed the issues and I was able to get data via mobile network again. Bluetooth seems to be the main offender.
This exact thing used to happen with my N1, and this was fixed with rooted builds (Cyanogen/Enomther) from what I saw...... *grumble*

Sorry to resurrect such an old thread here, but I'm having data issues today in the Chicagoland area. Anyone else having problems?
I first thought it was an issue with the latest CM7 nightly I flashed last night, so this morning I reverted back to CM6.1.1 and still having problems with data. It shows I have 3G/H and strong voice signal, but no data is coming/going. When I reverted back to CM6.1.1 I did a complete wipe and then nandroid restore.
Thoughts?

what's wrong with the service today

I don't know if this is happening to anybody else but today all day i had no service at random times, the onlyt way i'll have service for a couple of minutes is if I shut the phone off and turn it back on but it only last a couple of minutes and then no service again. I live in new york has this happened to anybody?
This happens to me occasionally, but I live in an area with crappy signal. I've found that my radio "Gives up" sometimes.
Solution: Use anycut to make a shortcut to "operator selection" you can select tmobile and you're right back on without restarting.
When this this start happening to you,cuz where I live the service was always great until today and I had my phone for about 2 weeks now with no problems until today.
T-Mobile is already aware that there is a problem with the network and working to fix it.
yeah i just read another guy's thread about the post,thanks
I didn't even read that it was your thread, my fault but is it a problem that only affects g1 right now cuz my girl and my mom are both on tmobile and they're phones were fine, my girl has my old wing and my mom has a blackberry

Nope t-mobile said it is affecting voice and data for all phones. Although this could be in certain areas. I can confirm the LA area is having voice problems on 2G phones as well.
oh, thanks for posting the info,if you find out more let us know.
Well now that I think about it it has happened more than usual today, maybe even yesterday? It's hard to tell. I sort of live in a black hole.
just noticed... I am now able to get my location using the 3G network only... weird... and service is back in full for now LOL
The g1 is only affected because it is the only device that t-mobile sells that has its own apn's
Data is cutting in and out in PHX for me... Making my poor GPS useless...

Yeah I'm on border of scottsdale and phx, get 3g here. Mine has done this ever since I got my g1. I'm gonna try the shortcut idea, I usually turn off and on and it works again. Not just today for me.
This is not a G1 issue or a 3G issue. This is a network issue with all of t-mobiles networks. They are working on the situation and it should be fixed.
all internet or just g1 data problems
Here it's just the g1 (utah) My G1 has been spotty. My friend has a wing. I was trying to troubleshoot. Wile I couldn't connect, he connected just fine. We tried this several times during the day. This has been going on the last 3 or 4 days. Love my G1!
I am in Detroit and my phone was fine all day long. A few minutes ago I just noticed that my 3g icon on the top bar is gone, I tried using 2 g networks only and still no data service. My phone works for regular phone calls and wi-fi but no data coming. I will re-star the phone to see what happens.. Anyone else having this issue???
Just did rebooted and 3G is back on and working...

serious 3G/EDGE issues with my G1

I have a rooted G1, iam running JF 1.42 RC33, i also have RC33 Radio.
i live in Chicago in a place where the 3G coverage is pretty good. in fact a month ago i was having perfect reception on my G1.
recently; i am having many issues with the data link (3G, EDGE)
simply, the phone does not pick the data link properly, and even if connected, it might drop the connection.
sometimes i have to go to settings, wireless, mobile networks, and click on "use 2G only" a couple of times to trigger the phone to connect... it will drop the connection when it goes to sleep !!!!
i have noticed that many times when the phone sleeps, it does not switch properly between the wifi and 3G [or EDGE], so i dont get my emails.
sometimes a reboot solves the problem, and some times it does not
i tried to flash the radio image again,,,, it didnt solve the problem.
any help will be highly appreciated.
If you've tried to reflash you radio and the results are the same it may not be your phone. It may be the network itself. You should call TMo to see if they have any issues in your area. About a month ago half the country went out for also half a day. It's rare but it happens. If no one else is having issues then it's possible the problem would be with the phone. You could try a wipe and/or reflash but it probably won't make any difference since it sounds like the radio (which you already tried flashing). Maybe also try checking to see if turning off data roaming will make any difference.
thank you for your response:
iam having this issue since a couple of weeks,, and i dont think it is a network issue.
i have tried to disable/enable data roaming,,,, it didnt help.
am i left to a "wipe" only.. ????
well you can give that a try and if that doesnt solve your problems then it may actually be a defect with your phone. also... ive had issues that my phone would lose data and voice even while i was on the phone. it would just disconnect then say no service. the problem wasnt my phone though... it was my sim card. if that sounds more like your problem you can get a new one for about $20 through a tmobile store.
i didnt encounter any voice call drop issues.
when i wipe, i will need to reflash everything, right?
I live in the chicago area as well and my edge/3g has been off and on like crazy over the past 4 or 5 days. I will look at my phone and it won't have an E or 3G. I'm running jv1.42rc33 with apps and caches to sd card. I'm not sure if its a network problem or my phone itself.
So you both live in the Chicago and are having issues with 3G/Edge and you doubt that it's a network problem??? I hope you didn't do your wipe yet.
I'd call T-Mobile and ask to speak with their data support (Tier 3) group and verify that it's a problem with your handsets before you do anything (like reflash, wipe, etc).
i live in chicago as well.
T-Mobile was/is having 3g network issues. T-Mobile where not aware of the issues. They say they are on the issue to solving it. :

I didn't explain myself well there. I'm under the impression it is a network problem. I learned my lesson last time there was an outage. I did like three wipes in four days thinking it was my phone.
It isn't you - my 3G (also Chicagoland) has been up and down since Wednesday. It is completely down again this morning. All day yesterday it was probably up for no more than an hour.
F'ing T-Mobile made me wipe my phone, then drive to the local store to get a new SIM, and they refused to acknowledge that it was a network issue. The sales rep at the T-Mobile store was having the same issue.

DOH! That sucks! LOL. If you're referring to the outage that we had about a month ago I took the liberty of posting a thread on here warning people not to wipe because they might not be able to sign in because of the network issues. There were so many that did and I was almost one of them myself until I wised up and decided to call first.
hello guys,,, thanks for everybody who in contributing in this thread.
i can see iam not the only one having issues in Chicago, t-mobile said they had no problems,,,,
what makes me tend to believe them is sometimes if i play with the phone the 3G shows up,
this is an experiment for you to try (it worked for me):
enable tethering using the open source gui, then disable it again.... 3G shows up !!!! even if you enable wifi... the phone will switch properly between wifi and 3G (when sleeping).
it worked for me last night and is still working now.
if you guys try it and it works,, this means t-mo has no problem,,, and we need to figure out what is wrong with the combination/configuration we have...

semi-random network disconnections

I have a mytouch currently running TheOfficial TMO US v1.7.1. It's been reflashed with the latest 32B radio. I've been having problems with the mobile network connection randomly dropping out, meaning it shows an "x" instead of any bars at the top. While in this state, it won't receive or make calls at all. I've tried unroooting, had the phone replaced by tmobile, gotten a new sim card, and still get this problem.
The most common time I see it is when I unplug the phone in the morning after leaving it charging all night. I'll glance at the screen, see it disconnected, and turn airplane mode on then off to reconnect. A few days ago, it happened in the evening and I'm guessing remained disconnected for about an hour, since I got a voicemail and didn't receive the notification until I did the airplane mode toggle later.
I don't know if this is a problem with the T-Mobile towers, but I don't think so since other phones don't seem to be running into this problem. Reception in this area is generally very good and I've never had this disconnection issue before over several different phones.
Is anyone else experiencing anything like this? Any suggestions?
ETA: Sometimes I've tried going into the mobile network settings and running the carriers search, and it gives me the message saying the SIM cannot be registered on the network, then the message stops appearing after a minute and the phone connects just fine.

Found the thread: http://forum.vodafone.co.uk/index.php?showtopic=25796&st=0
Most of these guys seem to be describing exactly the same problem I'm having. Are any other US T-Mobile users seeing anything like this? According to their coverage map I'm in a very solid voice + 3g data area.
In the meantime, I'm gonna turn off 3g for 3 or 4 days and see if these outages continue. I'll post an update in case other people run into this issue.
Another update:
After two days of trying "use only 2G networks" my phone didn't do this disconnection thing even once.
Something similar also seems to be posted as an android bugreport, although he doesn't go into the problem of "your sim card does not allow a connection to this network": http://code.google.com/p/android/issues/detail?id=2845
Another data point: a family member just purchased a mytouch today, on the same T-mobile plan but different line, and to try it out I set it up and watched it, and within 2 hours of being connected to the 3g network, it switched into the disconnected mode, and refused to register the sim card on the network.
So far, 3 phones, two different SIM Cards on two separate lines, and identical symptoms on each...
I will be trying an ./adb logcat at some point to see if I can catch the problem and complete that bug report.
For the record, I'm having this exact issue. Phone was fine for about 5 weeks, now I'm getting the same problem you describe. Any news or ideas?

Since I had my phone replaced for a faulty back plate, and the replacement phone having 0007 hboot fw - I haven't had this issue at all. Two weeks and counting.
Wife returned her phone under warranty for continuosly dropping signal and got supposedly reconditioned replacement handset back with 0007 hboot. This would seem to confirm this is the new default rom version.
Folks in U.S. on 0005 have confirmed they get the dropped signal issue, so I would also presume that between 0004 / 5 and 0007 a fix has been made.

2nd phone same problem.

Hey guys, I bought this phone for my wife about 3 weeks ago and we having severe issues with it. It seems that there is a problem with going from wifi to cellular signal. Sometimes the phone wont get a signal until it reboots and at times it dosent even do that. Also data has been non-existent except for the first days we had the phone. I don't think we could have gotten two defective phones with the same problem.
At first we thought it was the sim card, but we went to Tmobile and changed it out, also I used my sim from my Vibrant and did not work as well but her sim worked just fine on my phone. I am also noticing the wifi signal is very weak compared to my Vibrant. I though this phone was superior to my Vibrant hardware wise, but I'm starting to think otherwise.
Can anybody shed some light if you have had the same issues? My wife really loves the phone and she just wants it to work properly. What settings do you guys use under wireless and networks?
Have you tried factory reset? That will give you the original wireless settings that everyone else uses.

Atrix Loses Internet Connection With AT&T

I've had my Atrix for a couple of days now, and twice internet connection with AT&T just stops working.
Going into airplane mode and then back to normal still does not fix the issue. Wifi works, however this should not be the solution.
Besides AT&T Gimping our HSUPA speeds and not providing an app for the FM Radio, the loss of internet connectivity is pretty annoying.
So far the only way for me to resolve the issue is to shut down or restart the phone.
Has anyone else experienced this? I have not rooted my phone yet because I want to see how things work stock.
Any information would be appreciated.
Thanks!
I had this happen to me 3 times already..among all the issues i am seeing with this device.
You are correct, nothing helps but a reboot.

Gimping the HSUPA is...but how are not providing an FM radio app and the connectivity problem you're having AT&T's fault? Nobody else seems to be having a problem losing connection (meaning it's either you or your device that's gone bad) and the FM Radio not having an associated app is Motorola's fault.
Assign blame where it's due, plz.

Because AT&T is the APN providing internet access to our phones. Motorola has the FM hardware built in, AT&T is not making use of the FM Radio hardware which is already provided by Motorola.
If I was the only one with this problem, then others would not have stated they have the same issue.
So I blame AT&T when there is no connectivity on my phone because I'm paying them to be my service provider. AT&T also has restricted many features on phones which have applicable hardware.
Besides, you are not the authority as to who I wish to blame. If you don't have anything useful to post, then I suggest you just stay quiet since your reply is just wasting our time.

Mine has done it several times. It seems to happen after the connection drops for a weak signal. Then for some reason never comes back on. It is not just my internet connection, it is my entire signal that never comes back. I can't make calls either.
Same here, several times... id expect a patch coming shortly to remedy some of this BS.
i think all of these network issues all arond may be due to a deadline att has not met and is severely late on its 4g. Its prob updating its system. Just speculation.

I had the same problem today. I turned my wifi on because I was home and then I wanted to test my 3G speed at home. Turned wifi off and then I lost the data connection. It showed the H+ symbol and full bars but not the arrows below the H. I had to reboot the phone to fix the problem. Airplane mode didn't help.

I am new to AT&T and I guess I got a new 4G sim card. At least I had not an old one from another phone. Is there a possibility to distinguish them for me?
