I have a rooted HTC Sensation running SelfKang's alpha10 CM7. I'm a T-Mobile customer based out of the Minneapolis/St. Paul area. I've had no problems of note with CM7 at all on Sensation. But...
I recently travelled to Florida and had no problem using phone and mobile data (outside of generally spotty network coverage). However, I went on a boat tour that took us several miles off the coast and (presumably) out of normal network range. I was able to access roaming when out there, but when we returned to land, I couldn't connect back to the T-Mobile network. I've tried toggling airplane mode and rebooting, I wiped and reflashed CM7 and I also tried flashing a different ROM (EnergyROM), all to no effect.
I've looked around the forums here and elsewhere and seen a few mentions of similar issues, but none of the proposed fixes I've applied have worked. I haven't changed the APN settings from what they currently show, but I did confirm with another working user that my APN login info is correct. I tried my sim card in my girlfriend's phone (an HTC Espresso running CM7) and it works fine and conversely, her sim won't work in my phone. When I "Search Networks", about half the time I get the "error searching for..." message and the other half it sees T-Mobile and AT&T, but I get "Unable to login to..."
The problem seems to be isolated to my phone (after the sim card test) but I can't figure out if it's hardware or a software/ROM issue. Everything else on the phone works fine (Wifi, programs, etc.) I've stopped short of reflashing a newer or older radio; I'm currently on 10.56.9035.00P_10.14.9035.01_M.
Any tips or fixes anyone can suggest would be much appreciated.
Thanks
reset the apn to default regardless of what you can see then do a battery pull from switched on reboot do a manual network selection should sort it for you
hmm...did those steps. I get the same problem.
Manual search for networks either gets "error searching for networks" or T-Mob and AT&T show up but selecting T-Mob get me "unable to connect at this time". This is all while showing no bars.
Did you try a factory reset?

Hello all. It seems as though I've come across a pretty serious issue with my Dash 3G. I have been using Ookba's 3VOLUTION ROMs for some time now and over the weekend, my phone suddenly stopped being able to make/receive any calls. I re-flashed the phone to the latest 3VOLUTION ROM (04/10/10 build) and it hasn't fixed the issue. I've put the SIM into another phone and it works perfectly, so I know it's not a bad SIM card. I don't know of any software settings that can persist like this (after a ROM flash). Furthermore, why it happened suddenly is totally beyond me. Does anyone have any suggestions I can try? This is terrible timing as I just had a job interview and I need to keep my "ears open" for a possible callback.
Thanks guys!
Bump - anyone have any suggestions?
I have the same problem. I switched from my personal SIM to my work SIM (another provider) and now it looses the service contact after a few minutes.
I realized this happens when I have the data connection on and the GPS on at the same time. This happened to me the first few days with the original ROM too when I first got the phone. So when I use google maps or evernote with gps, the phone service shuts down. Weird.
Mine is the Ozone by VZW (CDMA) but after it was flashed to the 3VO ROM on WM6.5, I got errors on the GSM side when using the T-Mo prepaid Sim, data connection was turning itself off so I couldn't even access T-zone (which was working just fine earlier, already unlocked & running 6.5)
Took me a while to check, goggle & search - realized that some of the GRPRS & Proxy settings were locked by default to the VZW embedded Sim, and had to go into Connections & under Advanced (Menu - Right Soft Key)
to change it. Sort of tricky since the wap, mms & other settings were all set properly but it was easy once I changed it to T-Mo's proxy & WAP names as created. Same for using AT&T's MEdiaNet, as otherwise, as soon as the GSM network was found, data connection was turned off.
Take a look at yours and check the various Menus & Settings screen to see if it might've been reset to default, etc. etc.
Anyone Figure This Out?
Just happened to me this weekend (T-Mo Dash 3G). Simply stopped connecting to the network for voice or data. Worked fine on Saturday but dead Tuesday morning. Also running 3VOlution ROM. I called T-Mobile and we played with network settings, etc. but no luck. Tried a hard reset and that was no help.
Reset and rebooted countless times after changing any setting I could think of. Hopefully someone has figured this out or it looks like I'll be buying a new phone tonight.
Bad SIM ...

Was a bad SIM. I swapped mine for my wife's and the no signal followed my SIM. Dropped by T-Mobile this morning on the way to work and they gave me a new one free, no questions asked. Phone's back to normal.
Hello all,
Lately (meaning, the last couple of days -- perhaps 3 or 4), my phone has been unable to get a Verizon data network connection for a certain amount of time (4G or 3G). WiFi works fine. However, anything else doesn't work, say, for a few minutes, or a hour or so. Sometimes, a reboot will fix the problem, but sometimes it won't.
The odd thing is, the "4G-LTE" icon is displayed and shows activity (up and down arrows blinking), yet I can't browse the web, update the weather, update Facebook, check email, etc., etc.
Does anyone have any ideas? Running BAMF 1.3.2. I am in the middle of NYC (plenty of 4G service). Yes, Mobile Network is enabled in the Settings. Tried a battery pull as described above AND a SIM card pull. Still no fix.
I had a similar problem a few days after I got my Thunderbolt. I was still on stock yet. I ended up going to the Verizon store and they did a hard reset to fix it. It sucked because I lost all my data but since it was new I didn't have much on it. If you back up everything with Titanium Backup it shouldn't be too bad tho, factory reset is under "SD card and storage" in the settings menu.

There have been many problems with the TB and data/network problems as of late. I believe it to be because of this new 4G rollout that is coming Thursday, plus the fact we will be seeing an OTA quite soon they are propbably preparing the network for that, thus giving all of us all these weird problems that we have been having.
(everything above is just rumor and based on my 100% factual opinions )

You are describing the same problem I'm having and I also live in NYC. But, I have no problems getting data when I force the phone into 3G mode only.
I notice the data connection problem even though the 4G symbol is up when I don't have cell reception for a while...like being underground while on the subway.
Turning the phone off and on or rebooting seems to fix the issue. I'm thinking the phone has handoff issues with whatever tower is near by.
Anywho, I did the "data fix" by changing the EVDO setting from eHRPD to Rev. A. I dunno if that'll do anything.
So out of nowhere, my HTC Sensation no longer connects to the network. I would get roughly around 5 mbps around my house, but just all of a sudden, it stopped working. I tried rebooting the phone, and turning on/off airplane mode, and it just doesn't seem to be working. Anyone have any more tips before I try and factory resetting? Also i think I may be experiencing a bug because every time I open any app, I get a very quick glimpse of the weather instead, and then the app opens up. Thanks
What was your previous phone with t-mobile? If you don't have an "android plan" it seems that T-mobile is blocking you from data.
Check this thread: http://forum.xda-developers.com/showthread.php?t=1128335&highlight=data&page=5
I had the same problem two days ago and had to do a factory reset to solve the problem.
Previous phone was MyTouch 3g, so I'm sure I'm on an android plan
Thanks for the link, I'll check it out
Don't assume it's your phone. It's possible that service in your area is down. If you have another t-mobile phone check to see if it has reception. Next go into settings, wireless&networks, and select mobile networks. Then choose network operators and select automatically. If nothing comes up I would call t-mobile because resetting your phone.
I have double and triple checked the APN settings. No luck. I feel like a complete retard, but why cant this phone connect to the network?
It doesn't even appear to try. Any suggestions?
I haven't a clue why, but I've been told multiple times that the infuse won't be able to connect to Tmobile data services in any manner.
I'm in the same boat, when did you notice this? I ask because mine just started doing this yesterday. Here's a brief synopsis of what I've done:
- I was running stock GB 2.3.6, from the Heimdall One-Click...had no issues for weeks (only had it a few weeks); once I realized that I can't get anything higher than EDGE speeds due to the hardware requirements, I went ahead and purchased the GN. So, my neighbor told me that she went to T-Mo (same phone) and the gentlemen 'input some codes' etc etc and she now had 3G (can't verify, I didn't grab her phone). I had an idea that he went into the phone testing mode (by doing the *#*#INFO#*#*) and maybe changed some of the network settings in there. So I figured I would give it a shot before I put it up for sale since my GN was coming today. So I went in and tried a few things, all to no avail....and then realized that I had NO data at all.
So at this point I did a factory reset (no luck), flashed the firmware/modem/etc from the Heimdall one-click, reset the APN settings (multiple times)....everything that I know to do with it....and STILL no data. But I can place calls, get texts, etc with no issue.
What's strange is after I flashed the stock GB rom, I went back into the testing mode (I guess that's what you call it???) and was checking a few things:
- if I run the ping test, it comes back null (no surprise) BUT it also lists 'GSM Service: In Service' and 'Network Type: EDGE'...it does show GPRS as disconnected.
I tried my SIM in an unlocked iPhone and it didn't have data connection. But I also put my roommates T-Mo SIM in the Infuse and it didn't have data either. I haven't had a chance to see if my SIM works (data wise) in the GN, because I haven't gotten it yet.
Any ideas on what to do?
**EDIT**
For some reason the data began to work about an hour after I posted this. Maybe the phone knew I was asking the experts and it had no where to hide?? Either way The_Joe I would try to maybe do a factory reset and if that doesn't work, to try to re-install the ROM/OS again.
I've read a lot on the internet but have not found a good answer for me. In certain locations, almost daily, I get either a "not registered on the network" message or a "sim not allowed ##3" message on my Infuse. If I switch the phone to airplane mode and then back off of airplane mode it always reconnects to the AT&T network. The problem started after I changed my ROM from Infused 1.5.3 to Zeus 6. I've flashed to Mind of Mac 1.4 but that didn't fix the problem. I've tried a new SIM card, different APN settings and several other changes, but it didn't help. If I have a good 4g connection it never has the problem. It never re-registers on the network until I do the airplane mode on and off thing or reboot the phone. My iemi number shows up weird on the phone too. What is the best way to fix this problem? Thanks.
No one has a clue?
No one has a clue how to fix the problem? It happens when I lose 3g or 4g connection.
What modem do you have?

Modem
I currently have UCLB3. I have tried a few different ones but it does the same thing with each one I've tried.
Sounds like you know what you are doing , unfortunately it sounds like a hardware issue. If going to settings > mobile networks > network operators and choosing AT&T does not fix it the only thing to suggest is return for repair or exchange. As you know, you will have to return it to stock so after you do that you may want to test it one more time. Sorry, not the answer you wanted but the best answer I have, Regards.

From recent experience - I would avoid using the fixes listed above as they will change your IMEI.
I say this as I was having a similar issue -- I had been running on the ParanoidAndroid ICS rom for a few days and my I997 started to do the same thing. Network connection was fine most of the time but it would occasionally drop out to no network. Except swapping between airplane mode didnt always fix it. If i rebooted the phone and it would pop up with "Unknown" Baseband Version, and no IMEI/IME SV until it connected again... whenever it decided to do so.
I flashed a few different modems to no avail.
Used GTG's stock restore... and it still showed no baseband or IMEI.
Searched through everything i could find and I found the 2 above posts. Being the cautious person that I am, I was skeptical to run the "fix" since I know playing with the efs folder can do.. fun things.. I backed it up with EFS Pro.
http://forum.xda-developers.com/showthread.php?t=1308546
So after that - I did the fix from those two posts. It worked. I got a signal. HUZZAH. But I could only make a few calls before it would drop out, and I couldn't send or receive text messages at all they would just stall and error out.
So I took a look at the IMEI again and noticed that it was NOT *my* IMEI, it was presumably the imei of the person who Truckerglenn got the backup from so long ago.
Figured at this point my phone is going to have to go back to Samsung to fix since it's still dropping out, the IMEI is wrong and I can't send texts
Can't break it anymore than it's already broken right?
Go back into root browser, delete the EFS folder entirely. *poof* gone. Reboot. Use EFS Pro to restore the backup I had created (GOOD THING!) phone reboots. Instantly picks up the signal again, I get 15 text messages, 2 voicemails AND my IMEI shows what it should be now.
*HOPEFULLY* it holds onto its connection now. If not, back to stock and back to samsung it goes - now with the correct IMEI. heh
Sorry for the long story
Thanks! May have found a partial fix.
Thanks for the tips and information. I think I may have found a partial fix. It seems that picking the "WCMDA only" in the "Network Mode" options seems to solve the problem for me. If it is set on "GSM/WCCMA (auto mode)" option, it seems to cause the "SIM not allowed ##3" or the "not registered on the network" problem when I am in an area where the 4G or 3G signal is weak. I will do some more testing. It appears that if I don't have 3G or 4G available in any given location my phone won't connect to the cell towers at all even though other users can connect without any problems. Does this give anyone any other ideas? Do I possibly just need new APN settings?
Have you tried flashing a new radio? Does a complete wipe and restore to UCLB3 make any difference?
Has any of these roms/firmwares that you flashed been done so through Aroma installer? I know Aroma gives you the option to change modems, and if your download was buggered that could have caused it.
I'm just tossing ideas around here... I'm up early and looking to help.
The work around works
Yes, I have flashed the radio but that didn't help. I have discovered the "fix" is to set my phone on "WCDMA only". It seems that the phone will only work if 4G or 3G is available. I am not longer getting the original error messages. So that's a good thing. If I ever go to where 3G and/or 4G is not available I will have to try something else. Thanks for all the replies.
