I have had 2 different vibrants now and they both have done the same thing. I haven't been able to isolate the problem to any one thing so I ask if there is anyone else experiencing the same problem. My network connection just freezes. I can't call or text and I have no data. If I try to make a call, it freezes on dialing and the only way to get it back is reboot. This is happening about twice a day and is really a pain. The only way I know it has happened is by trying to make a call and it freezes. I don't know how long it has been that way and when people try to call me, it goes straight to vmail. I put a new SIM card in thinking that was the problem, but it didn't help. I have searched everywhere trying to find a fix. TMO CSR was absolutely no help at all. Shocking.
BTW I am in an area with no 3G coverage. I am on EDGE all the time.

Since you have had the problem now with two different phones it could be a result of some app(s) you have installed, or related to your coverage. Did thr problem start after having each phone for some time?
I am working on ruling out an app. Weird thing is, I have had winmo for over 3 years in the same area with no probs. This is my first android. I am uninstalling an app at a time to figure out if it is one.
****Update****
So I uninstalled the ESPN Scorecenter app. I haven't had a freeze in over 24 hrs. Guess I am going to have to find another app to follow the games while I am at church.
are you sure u r in area that has only Edge? have u try to Lagfix the fone?
goodluck.
This just happened to my wife's Vibrant. This reminds me of when I had the T-mobile Shadow, where suddenly, it would not be able to send or receive data or calls BUT the phone itself shows no indications of any signal problems. It's as if the cellular software component has frozen and so the signal bars are frozen to whatever state they were and thus tricking you into thinking everything is fine until you try to make a call or someone calls you on a landline wondering if your cell phone is dead.
I suspect it's due moving into a poor or zero signal area and the phone tries to make a data connection. I really have no idea how to fix this other than to hope there is a firmware update to resolve this. The only fix is to reboot the phone (flipping the phone to flight mode gets one to a state where you can't turn flight mode off... which indicates a lost of control to the cellular component).
I am consider finding a way to reboot the phone nightly, which will help if this happens overnight, but I wish there was a way to detect this more immediately so it can reboot when needed. Perhaps an app that monitors the carrier signal strength and if the signal level is perfectly the same for a long duration, then a lock up of the cellular component is suspected.
Hello Just wanted to say thank you to all the peope who support this awesome website.
I got my TBolt yesterday and i know people have said they have had weird reception for 4g and what not. Luckily my house is in the center of a 4g area so in my house i have had perfect 4g coverage but today i went to town and i looked like it was trying to switch from 3g, 1x, or 4g but unsuccefully as it would only stay for a few seconds then disapear. Does this have to do with Verizon problems? if not what should i do?
Thanks
I was having the same issues going back to 3G from 4G. I would get no icons on the top of the screen and could only make phone calls. Tech support had me do a factory restore and that fixed it right away. Very annoying for sure to have to set up your phone all over again. If this keeps happening I'm not sure I will keep the phone. I am not about to factory reset every time this network handoff issue occurs.
Tech support told me they are working on a fix and I don't need to hard reset it yet. To me its silly to hard reset if its just going to happen again.
i was having similar issues and tech support had me take out the battery for a min and then put it back in and boot up and i had 3g back
Battery pull didn't work for me...
thanks guys battery pull seemed to work well!
Local VZW store said a national tech support email went out this afternoon regarding TB problems switching and dropping data. Email said the fix is on the network side and the phones have to be hard reset after 1PM mountain time to be fixed. Sounds fishy, but maybe worth a try.
I saw this linked in another thread. I take no credit for it.
http://forum.androidcentral.com/htc...blems-3g-data-dont-hard-reset-read-first.html
It helped me a little bit with my sporadic 3G connections here at work.
It appears vzw's eHPRD's network is down which is why data has been dropping once a tbolt is out of LTE coverage.
Use the ##778# menu (hit call after ##778#)-->password is 000000-->modem settings-->Rev A-->choose enable-->hit the menu button on the tbolt and commit changes
This is from the androidcentral forums. I can't post links yet, but a quick search over there will reveal the specifics.
This forces the device to use EVDO instead of eHPRD so you'll lose simultaneous voice/data, but at least if you're not in LTE coverage you'll get data. The device will still connect to LTE if it's available.
This worked on my device and my wife's.
I noticed that even in some areas of the same city that this network error is causing no access to 3g. I tested it by following the guide and sure enough the 1x switched to 3G. I hope Verizon gets this up and running. I think this is also causing calls to drop.
Sent from my ADR6400L using XDA App
God Dam ****ing verizon biooootch, angered me so much saying i couldnt get on 3g because I voided my warranty by doing *#*#4636#*#* and shutting of LTE. OMG I wanted to punch her through the phone.
I've been having an issue and I don't know if it's related, but it sounds like it.
I've been turning my phone to "CDMA auto (PRL)" whenever I go out for the day to conserve battery. But there's this one place that seems to disconnect me whenever I go. It's happened twice now, but when I go there, I lose data service and can't manage to get it back even after switching to 4G. The first time it happened, it was out from about 11pm to 3am. Today, though, I switched it to 4G and it came back, along with 3G.
Now, the problem here is that my girlfriend's Thunderbolt is fine during all of this. I'll lose 3G, but hers will stay connected even though we'll be in the same location. I don't understand what would be different about mine than hers. :S
Hey DJComent try pinggolf12's fix it worked for me.
For some reason today my Amaze decided to randomly stop getting any type of data signal. I will be able to place and receive calls, and send and receive texts, but I will not be able to connect to the internet, or anything requiring data.
If I go in to settings it will show my mobile network as on, but I will have to toggle it off and on a few times before it eventually comes back up. It seems the first two trys it will say "turning on..." and nothing will happen until I turn it off and back on, eventually getting data signal.
I didn't change anything this morning to prompt this, and I don't have any battery saver apps that turn data off when the screen is off. This is also happening both at work and at home, places where I have always had great signal before, so I am at a bit of a loss as to what is going on with my phone.
For reference I am running ICS 4.0.3, S-Off, and rooted.
It's a tmo issue.
Have others been experiencing this issue today?
All week.
Oh, I had assumed that people in the Midwest were experiencing problems with the storms and all, I didn't know they were having issues in California.
Thats a relief at least, I was worried there might be something up with my phone, which at the moment I can't afford to replace. That is certainly a load off my mind!
It's a nationwide issue, seems to be overload on the network or they're probably installing that new band.
Haha, well as long as it keeps me from buying a new phone it's all good. Thanks for the info!
Lol at getting a new phone, no prob, it should be back on in an hour or so.
Curious issue with my Titan II. Cellular data connection just fails at random intervals. Cycling airplane mode or rebooting the phone is the only way to get it back. HTC blames it on AT&T and AT&T blames it on HTC. I've spent hours on the phone with each. Even got a new Titan II from AT&T, but it went into this constant reboot loop, so I went back to the first unit.
Now comes the interesting part: I live in Detroit and have been traveling to FL quite a bit, this year.. and the issue DOES NOT HAPPEN IN TAMPA. Phone runs perfectly well, there. Here in Detroit, cellular data "up" time ranges from 5 minutes to 14 hours when static. 2 minutes to 20 minutes when driving around town. Drops are less frequent when streaming something.
HTC Titan II stock (FW: 2180.0400.118011.502)
Windows Phone 7.5 (7.10.8112.7)
4G SIM card (3rd one)
Appropriate data plan
Serious thanks for any ideas anyone has. Do I add an APN, throw the phone against the wall, or what? Please do not suggest I change to a different phone as that is not an option.

Yes, I'm facing the same issue.
It seems something related to wifi sleeping when the phone goes stand by and the solution could be keeping it alive in some way....like streaming..
I hope this will be fixed with AT&T Tango 8773 Update (Once it finally come....)

Are you sure you aren't hitting "black spots" on your network? If you have random connection drops in only particular area it is likely the masts and AT&T issue. I've swapped my provider from the one which did 2G/3G signals to 3G only provider. 3G only has better coverage and lesser black spots on the network and hence I hardly see any drops in connectivity. Don't hard reset or anything, it will only make you re-do the whole phone, won't help the cause.
Have you checked if two golden pins on the back cover are making good contact with phone?

Have to rule all of that out as it doesn't happen at all in Tampa. I can drive from Ybor City to Clearwater and back and never need to reset the phone. Here at home, I have four bars and will lose cellular data with the phone in a static location. Driving around in Detroit is guaranteed to make it drop cellular data even with the phone lit up and active. I can have Navigator running and it'll just quit loading maps and giving directions until I cycle Airplane Mode. In Tampa, this doesn't happen.
In Tampa, I've gone the whole week without any need to reset the phone. I can't walk from the gate to baggage claim in Detroit before it loses its data connection.

UPDATE: Cellular data connection is a little better with WiFi turned off. It won't lose it as quickly in a static location, but still loses it as I move between towers. Also had to reinstall a couple of apps that had stopped launching.
Is forcing Tango an option?
I have the same problem,
I live north of detroit.
my phone has been in to htc repair 3 times, i think they have replaced every part in it, the last time i got it back it held connectivity for 11 minutes.
this is on my home tower as well as several towers around me.
Normally all testing was done with wifi off, on towers where the lumia 900 and my wifes iphone have never lost data.
i have been waiting a week for a htc level 2 rep to call me.
we shall see
Keep me posted. Last time I spent time with HTC, they decided that - since the issue only happens in Detroit - that it was AT&T's problem. AT&T, naturally, claims that the problem doesn't appear on any other device, so it must be the device.
Can't wait for Windows 8 phones. I'm getting one.. ANY one.. the first day they go on sale.
Well I just got off of the phone with a level 2 rep from HTC, who seemed pretty confident that the problem is the rear cover. He is sending one out, and says if that doesn't fix it then it will be a phone replacement.

I'm more skeptical than you, trust me, but it would explain how so many people get the same problem with replacement handsets, as that piece is often not replaced
So, I'm in Florida for the week and noticed something.
In Detroit, the status bar says "4G"
In Tampa, the status bar says "LTE"
As before, I have not lost cellular data connection since I landed in FL. Kind of rules out the battery cover as the issue is gone, here. It appears the issue goes away in LTE areas while it's present in areas yet to get LTE. Detroit's LTE rollout hasn't happened, yet. So, it appears I've got another month of suffering before the problem is rectified.
One other note. With Internet Sharing set to ON...
In Detroit, my wife's laptop connects to the phone and can get internet.
In Tampa, my wife's laptop connects to the phone, but cannot get internet. It gets the error msg: "your computer is trying to use a dns server that is incorrect or doesn't exist"
My laptop works flawlessly connecting to the phone's Internet Sharing both in Detroit and Tampa. For the life of me, I can't find anything different in her settings over mine. Both are Win7. Hers upgraded from Vista, mine x64 and new this fall. Also, two internet-capable televisions connect to the phone and get to the internet flawlessly. But something with LTE doesn't like my wife's computer. Odd.
Honestly, I adore everything about this phone except for the data connection issue in Detroit (and a few other areas, it seems).
There HAS to be a setting or SOMEthing I can tweak to get this thing to work in Detroit.
Check battery cover, radio negotiation, firmware of radio

Hum.. that's curious. I had the original titan with similar issues.
I disabled wifi when not connected. I replaced battery cover also. The titan2 supposedly fixed that issue with the battery cover because it was a design flaw.
The radio supports 2G, 3G/4G/H and LTE. You may want to check it. You can set the radio it uses and not let the firmware decide which radio to use. You can check the service menu, I forgot the code. Just search for it.
If you use 2G, data and voice are not supported simultaneously. Check and make sure the contacts on the battery cover and on the phone are clear of debris. Use a solution to clean the contacts on the phone.
In the past I manually set the radio to 3G (HSPA and HSPA+) [HTC Pure, HTC HD2 on at&t]. The 3G radio is mature and should have less issues with the radio negotiation.
BTW, there is a keep alive wifi app also.
Thanks. I'll have to look for the codes. It's pretty obvious after going back and forth so much that the Titan II has a flaw with the way it handles AT&T's 4G. Scanning the maps from others who have had problems all show that they're in areas with 4G but without LTE.
Yeah, if I could force this thing to do LTE or 3G I think we'd be fine. It's the Best Phone Ever so long as it gets LTE, 3G or Edge. Anything else and it's crap.
Yes, back connector is okay and I've done this every way one can think of and kept notes. WiFi doesn't matter. On or off, the T2 will lose cellular data connection randomly in 4G areas. NOT in LTE areas. I'm only unable to test it on other carriers.
Similar problem with data
So I have had a similar problem -
I had a Samsung Focus, great phone, but I wore out the USB port - wouldn't charge consistently or sync. I figured I might as well use the insurance I had been paying. They sent me a Titan I - it had the bad microphone issue. So after some messing around they sent me a Titan II.
It has never had consistent data connection. I am in an area where I get the 4G icon (not LTE).
My experience tells me that if I move around and change cell, or lose signal in the cell I am in for any reason, then the phone will NOT connect back to data. It can (almost always) still get phone calls and send/receive texts and so on, but no data. Toggle airplane mode always fixes the problem, until the next time.
Originally HTC wanted to send me a new back cover - AT&T have been completely useless, they have no idea. Eventually after messing around with factory resets, powering on and off continuously, another new SIM card, HTC decided they want the phone repaired or replaced (level 2).
It is still inside the 30 day limit for exchanges from Assurion (AT&Ts insurance carrier) so it's getting replaced. I'll let you know if it fixes the issue, but I haven't been in an LTE area so I can't check that.
Personally I think it is a problem with handing off/reconnecting to 4G tower service - we'll see......
Anyone have the radio codes?
I've had the same problem since I got the device as well; but have noticed that it doesn't happen in all areas around me. My house is one of those areas though that I always lose connections. I've tried every APN / idea I've found on the internet with no luck. It's clearly something to do with AT&T towers. The only think I've not been able to try is a different SIM card in the same phone since it requires a '4G' sim card to even work at all. However the same SIM does work fine in '3G' only phones.
Going with the radio idea, does anyone have the codes to turn off the LTE radio? I just saw the list saying this phone will be long gone before AT&T ever gets LTE in Colorado so maybe just turning it off would help. Every code i found was for the T1 though and it didn't work on my phone.

UPDATE: HTC insisted on sending me a new SIM card cover (since it contains the radio's antenna). Despite my argument that the fact it works in Florida negates antenna as a suspect, they sent it along, anyhow. Naturally, there is no change. It still randomly drops cellular data. And now, I've picked up another spot on the freeway where my calls get dropped. Granted, it happened ONCE, so that could be any number of things. Long story short, it's not the antenna.
Next idea?
Well, I'm in Florida and found a spot where the phone fell back to 4G from LTE. Data issue returned. So, that takes geography out of the equation. The phone can't hold a data connection when using 4G. So, should I go for a fourth unit?
My addition:
AT&T recently rolled out LTE to my area in CT. I never had the problem before on straight 4G. Now, when I go from LTE to 4G (my drive every morning) data just stops working. I push it in to airplane mode and back out again and it works.
BTW - I am running Tango, so that is not likely to be a fix unless a radio update is released with it.

AT&T just switched on LTE metro-wide, last night. Now, the Titan 2 performs just as it does when I'm in Florida. It's nice having a data connection that'll stay good all over town, again.
I have spent some time discussing this with HTC and AT&T. Actually just got off the phone with HTC level 2.
I too have gone through all the options - new phone, new cover, new SIM card (you can just go into AT&T and ask for one, no charge), hard reset, everything.
From the information in this thread, and elsewhere I can say that the phone drops data on one of two things happening:-
- connection to tower is interrupted in current cell, but is re-acquired
- connection is handed off to adjacent tower as you travel to a new cell
Both these things will drop data IN 4G AREAS ONLY. If you are lucky enough to have consistent LTE in your area, you shouldn't have any problems.
Right now I'm working on getting the service menu codes so we can play with the radio settings. It sounds like HTC support reps have been forbidden to give these to end users on windows phone devices (I wonder why??!!).
If I get this information and it provides a fix for this issue, I will (obviously) post it, and I imagine HTC will as well. Here's hoping.....
Andy
Hey all, I've had my Evo for almost over a year now, and data was never an issue. As of lately, I'm unsure what caused this issue to start popping up, but my phone will have a 3G or LTE connection, but even if I don't move or leave the phone alone, I will lose the data connection and a popup in the notification drawer says "Unable to establish wireless data connection" where toggling data or airplane mode doesn't usually cause it to come back, it just does whenever it feels like it. I don't know whether it's Sprint, or my hardware, but this issue has been present for the past few months with no solution. I am on the latest radios, sense ROM, and learned about custom PRL's today (on 56019 now) and nothing has solved it. I've searched for anything on this device related to this problem and haven't found anything, so any suggestions or help would be appreciated
Any suggestion whether the issue is at least my phone or the network would be helpful. I have no clue what the cause of the issue could be. Thanks

I noticed this more frequently as well once I installed 4.3 a while back - seems like the radio is much more sensitive and would pop up that message occasionally when it would switch between 1x/3g/4g/Wi-Fi - or from roaming back to sprint. I just ignored it - dismissed message and all would be well.
however, sprints network has been more and more troublesome these past 4-6 months - actually switched to ATT beginning of May due to this after being with Sprint for 16+ years.
