4g works but switching to 3g/1x doesn't seem to - Thunderbolt Q&A, Help & Troubleshooting

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.

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.

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.

Evo 3D just stopped connecting to "Mobile Network."

Just sitting here at work, and I noticed my battery was unusually low for my usage today... when I noticed that my 3G icon was missing. I thought that was weird, because less than an hour ago, I had it for sure. I was getting email updates for work on a regular basis.
When I checked my quick settings, my mobile network just kept saying "Turning On," and would sometimes flash between that and 'ON' but never actually brought up a 3G, (or any data icon for that matter.) Texts are still getting through, but are about 2-3 minutes behind Google Voice popups on my laptop.
Has anyone else seen this before? I have rebooted, and tried Airplane mode, and disabling/renabling all the radios individually, and nothing has worked... Guess I should yank the battery now. Really bizarre. I usually get pretty good 3G service over here.
If it continues, exchange it.

Mine did the exact same thing this afternoon in Lubbock Tx. I rebooted, turned off and on and data always showed turning on but never connected. For some reason I ended up in the Sprint Zone and it then connected. It went into spring zone as I tried to connect to *2.
Don't have a good explanation of why it started working but try going to the spring zone and check data on.
The same exact thing happened to me too on my 3d today.

Did you do the "speedup 3D" trick that was posted where you removed the proxies after typing in your MSL password? If so, undo it, because that's your problem.
I haven't messed with any settings. I pondered it, but I haven't received my MSL code yet.
I did just find out that my coworker lost his 3G on his Epic. I think this is a Sprint issue, and not any of the devices... Scary though.
Austin, TX here.
im experiencing the same issue right now here in north austin, tx. im getting basic phone services but no network (market/FB/web/etc.)
and no I did not use the speed up internet fix.

well seeing how there are 3 texas people here experiencing this issue it might just be issue with sprint
Maybe they are upgrading the equipment of the "node".

Well I just came back from BestBuy and picked up the 3D here in Michigan. Everyone in mobile just about had Sprint and no one could connect to 3g. My Evo 4g had a very limited connection. As soon as I got the 3D, it couldn't update the weather. So it is definitely something going on with Sprint right now and not your phone.
Just came back for me... Ben White / I-35 area. That was weird.
Are you sure your power saver settings aren't disabling your data connection due to your phone being below the % you set it at?
I don't think it's a 3d problem. I've had trouble connecting to 3g here and there with my og evo about 2 weeks before the 3d came out. I seriously think sprint has some serious network problems.
Man what is going on with Sprint? It's been happening a bit today as well.
I installed golflogix and it gave me an error message and forced closed the program and also put the 3d into airport mode.
However, golflogix will work on 4g.
There seems to be some problems with the sprint network or the 3d.
I had this same issue over the weekend. Rebooting the phone never worked so I did a factory reset and havent had the problem since. but it does make me a little apprehensive.
Perhaps the network is experiencing outages as they roll out an upgrade to their data network to proactively detect unauthorized tethering activity so that when HTC imminently unlocks the Evo 3D, they can charge backdoor tetherers appropriately.

[Q] Mobile Data Drop - Not Suspect To Outage

In the past two weeks, my mobile data has been down. I don't believe it to be an outage in my area due to the duration of the problem, and the inconsistency with other Verizon Wireless phones. I was running Juice Defender for a while, and every now and then I would notice that the Mobile Network would drop. Toggling the Mobile Network would not fix the problem, either. I usually cleaned out my cached data for the Juice Defender app, turned the app off, then toggled airplane mode once. (Sometimes just toggling Airplane Mode wouldn't fix it, therefore I had to clear the cache for the app.) Now this fails to work. I cannot get my mobile network to connect by any conventional means. When I receive MMS messages, my network will connect long enough to download the attachment. Also when I do a search for a Software Update, it connects just long enough to tell me there aren't any updates for my phone. I've tried updating my PRL with *228 and I've even tried *18 from a post over at Droid Forums. Neither work. I've removed the battery and SIM Card as suggested in some other threads here at XDA. I've also removed the Juice Defender app.
The phone is not rooted and has never been rooted with the Temp Root methods. I'm not opposed to rooting, but if I root, I'm gonna perm root and I would rather not have to factory reset my phone if I don't have to right now. I'm mainly posting this because I cannot find anyone online with the same issue that I am having. Any help would be appreciated. Personally, I think its an issue with Dalvik-VM. I can attach a copy of my LogCat if needed. Any ideas on my issue? Thanks in advance!
Check your power settings, if you are in economy mode it will mess with your data connection.
I have a paid version of JuiceDefender, it has caused me so many problems I don't even bother to install it anymore.

I also have the same issue, tried a couple basebands and could not fix it. I ended up not using it...
Every once in a while my mobile network or just lte somehow gets turned off and I have to turn it back on, but that's rare.
I tried juIce Defender and also had problems losing my connection so I uninstalled it. Plus the settings were so confusing to me. I'm using Green Power now and that seems fine.
You didn't mention mhs so I assume you're not using it but that has known connection issues.

Juice Defender gave me fits, too. I'm not using my phone as a Mobile Hotspot, either.
I kinda think its my ROM. I'll play around with some stuff, or I'll just get around to doing a factory reset and see if that fixes the problem. I'll post any solutions here for others.
Are you in a good 4g area? If you scroll down the general section here, you will find my topic. If you use 3g more than 4g, there is a post in that thread about##778#. It helped me. Sorry if it doesn't help you, Cheers.

I just wanted to let you know that I'm having this problem as well. I AM rooted and running CleanRom, but my daughter has a non rooted Bionic, and both of us suffered a complete loss of data today. My husband's rooted Rezound is fine.
I took my phone into Verizon today, and after initially just trying to swap out the phone (which I wouldn't allow them to do, it took me too long to get my phone the way I want it), they finally switched out the 4G sim card, and the data came back instantly.
When my daughter leaves school today, she will get her 4G card swapped out as well, and we'll see if it is in fact a network connectivity problem.
It seems to me that our 4G phones has a lot of trouble switching from wifi to 3G/4G service.

I will +1 this. My work WiFi is spotty, and so the phone falls in and out of WiFi. The Rezound HATES that and usually leaves me with no connectivity. There is definitely a WiFi->Mobile Network issue.
Try doing a factory reset. Could be a bad device... Im getting amazing reception on mine. I havent even seen my 3G or 1x icons yet. Constant 4G lock.
Forget what I said, my data connection has been dropped again for the past thirty minutes and there's no way for me to get it back.
I'm going to try a factory reset. I *really* don't want to have to send my phone back because my husband is getting amazing coverage on his Rezound. However, we're still in the first week of our Verizon contract, and if this looks like it will be a standing issue, then we'll have to cancel and go crawling back to horrible Sprint.

I think I'm going to try doing this. How painful was it for you to convince them to give you another SIM Card?
Edit: Just read your last post. Please let me know what a factory reset does for you.
They had no issues at all swapping out my 4G card, they certainly couldn't let me walk out of the store with no signal. They knew they had to try something.
The factory reset on the phone appeared to work. I've been steadily switching it from wifi to data, and the data signal picks up, albeit a tad bit slow. Only thing is, I still don't really get 4g, while my husband's Rezound has a great signal.
I got insurance on the phone, so I'll put up with it as long as I can before I start screaming at Verizon.
Good to hear. I'm going to try to switch out my SIM card today and see if that fixes it. I thought maybe it was something with the ROM, seeing as how my 3G will turn on whenever I need to send an MMS message, so a factory reset made sense to me. I just don't want to do it. Lol. Thanks for the info!
I've experienced it twice in the last 24hrs and it just happened to be right after I installed and used LTE OnOff. Don't know if there might be a connection there. I keep forgetting this phone has the ability to switch 4g/3G unlike the TBolt. Needless to say, that app is no longer on the phone.
KORM via the beast known as the Rezound.
I had an issue with the mobile network just dropping in and out (other people in the room did not lose signal). We currently don't have 4G and it is 3G only. I did a factory reset of the phone, but it continued to occur. Took the phone back to Verizon store to exchange it (it was 1 week old). At first they weren't going to and gave me a run around but in the end exchanged it. Have had no problems with new phone.
My girlfriend's Bionic keeps dropping 4G more frequently than my Rezound. I get this problem too though. Usually a toggle of Airplane Mode fixes it...but it's pretty damn annoying. Happens once or twice a day!
A Factory Reset fixed it. Everything went smoothly, too. I backed up all my SMS Messages with HTC's Messaging app, and got my network back as soon as I restored it and set everything back up. Hopefully this will help anyone else who might have had the same problem.
I've been side by side with a fresh Rezound and watched both of them jump from 4g to 1x to 3g and sometimes never 3g. The problems were a million times worse with my droid charge as it's a combination of the handsets and the towers.

Hmmm
I have this happen if I am in an area with NO signal (such as the basement level of my office building) for long time. Only a reboot will bring back data. Does not happen often (maybe 2ce in a month and a half).
I am intrigued by the person who blames the install of LTEOnOff. I have it installed but do not use it. Maybe if I ever have to hard reset (such as if ever run the unlock), I will not reinstall that program.

[Q] 4G drops to 1X

I recently upgraded from the Incredible to the Rezound and find that when 4G not available, the signal drops down to 1X. Not only that, it seems to stay in 1X even when 4G is available. How can I get the phone to drop to 3G when 4G not available? The Incredible ran in 3G in the same areas that the Rezound drops to 1X. What do I have to set to get it into 3G?
Thanks for help.
both my GF and I have been having trouble with this on both our phones... We both live and work in 4G coverage, pretty strong coverage too. Yet we both see 4g drop out to 3g or 1x. Its very random, and I've had it happen right in the middle of browsing the web. (All of a sudden a page takes forever to load or doesnt and the phone acts like it has no data connection, I go to the home screen and see that I am all of a sudden on 1x..)
I recently read an article that talked about how VZW actually has a pretty major issue they need to resolve pertaining to authentication on the LTE network. I don't know the exact mechanics of it, but basically the authentication fails and you get booted off the LTE network until the phone tries to hop on it again. Right now, the two phones I have personal experiance with do not try very often to get back on and it often takes going into the wireless settings page and selecting mobile networks and going in and out of that screen a couple times, or if it is being stubborn, airplane mode, site for a minute, and then back on. Occasionally I have to reboot the phone.
It really irritated me good last night when I really needed the data connection for GPS navigation because I took a wrong turn in an unfamiliar area..
Sometimes going in and out of airplane mode helps or restart.
I'm not going to say look on the forums. Here is a quote from another thread and linked another thread.
had the same issue and fixed by this.

This changes your network from eHRPD back to EVDO Rev.A. For LTE phone owners, eHRPD causes 3G to die (most of the time anyway) when the LTE network has problems. Get back on normal EVDO and you're good to go.
^ from Jntdroid on another forum (not sure if we're allowed to post to other forums here) I'm not positive on where he got it from, but this is a capability of all HTC 4G phones
I've had occasional issues with being down to 1X, but even that was only during nationwide 4G network issues, definitely get in touch with VZW about that... not that they have enough sense to fix anything *sigh*

Same issue here. Only happens when I go from a 4G area to a 3G area. I end up getting stuck in 1x. The phone switches fine from 3G to 4G. But when going back to a 3G only area, it by-passes 3G and I get 1x.
No toggling helps. I have to reboot to get 3G back. I also tried that fix posted above. It does not help. Called verizon again tonight.
The strange part is before we had that 4G outage a few months ago, the phone would switch just fine. Now it's a pain in the ass.
Sorry it isn't helping. It worked in mine and done exactly the way it told me. Go from 3-4g now without an issue. No 1x like before

[Q] Losing signal on my Amaze 4G

Okay, here is my problem: Every once in a while I will completely lose all signal on my phone. It wont pick up 2G, 4G, nothing. Wifi and bluetooth both seem to work though just fine. I've searched and haven't found anyone with the same issues so I'm wondering if it's just my phone or if nobody has commented on it. I first noticed this about two weeks ago, when my phone refused to find service. I was stuck with the little X next to the signal meter. I figured I was just in an area with poor service and didn't think much of it. An hour later, still, no service. This time I went outside where I know I have good 4G service and nothing for 5 minutes. I enabled airplane mode and disabled it, still nothing. Turned the phone off and back on as a last resort. Still nothing. I ended up finishing the day with wifi calling as that still worked. Sometime later my phone began receiving service again so I thought it was a fluke issue.
Then, just yesterday the same thing happened. This was when I rebooted my phone (which bypasses the fastboot feature) and service was restored right away. I called T-mobile and they said there weren't any network issues in my area and they had never heard of this issue before on the Amaze.
So, this is where I'm asking if anyone has heard of this before. I'm running a stock ROM and it hasn't been rooted. Thanks for any comments!
This might help just a touch. I do live in an area with decent service but my couch and bedroom are deadzones for some odd reason. I bought these signal boosters for 2 bucks figuring "what the hell, I'll give it a shot". No more dead zones, and data went from E to G. Not a miracle worker but for a couple bucks it keeps a signal at least.

Wireless Coverage
I have 2 brand new Amaze 4G for a few months now and had no problem with the coverage. I know the coverage is good with full signal bars and have not found any issue with coverage.
Sometimes, different phones have different received signal sensitivity. Also depends on user behavior. If you are always using a handsfree device (cable or BT) and your phone is in a bag, then your coverage is reduced by your action. The best coverage you can ever get is when you have line of sight (unobstructed) to the cell towers.
There are a few issues with your problem:
1-Poor inbuilding coverage
2-Poor coverage in your area
3-Network optimization issue
4-Hardware issue
If you are going from 1 bar to no bar, then most likely you have coverage issue. You lost signal since the level is already very low.
If you are going from full bar to no bar, you might have hardware or network optimization issue. Try your phone is the city or area with known good coverage first. If the behavior persists, then you have phone problem.
I used to manage wireless network for carriers.
same issue
I've had the exact same thing happen to me. Red x, no signal except wifi, in places where signal is not normally an issue. Battery pull doesn't work, return to signal seems arbitrary. Had the same thing happen with my Desire. I have no answers, but you are not alone.
Yup, it happened with my first Amaze. I got it back in January and started playing with it - rooting, custom ROMs, etc. Then later that day, the signal just died on me. I thought I must've screwed something up, so I flashed back to everything stock. No luck. I waited for half a day, then it randomly started working again at night.
You probably noticed tha tI said that happened with my first amaze. That's because after that signal issue, I discovered that my camera stopped working. I returned it to T-Mobile and they sent me another one. This one is working great though.
Well thank you for all the input so far. Id like to say that this isn't my first cell phone and I'm not new to weak or poor signal areas, especially from T-mobile. I was using my phone at work at the time, which has anywhere from no signal to 3 bars depending on where you are. This wasn't one of the cases that I was standing in a dead zone when I checked my phone. I had no signal for several hours, including over 30 minutes of standing outside trying everything I could think of. I have had excellent signal outside in the past, exactly where I was "Hiding". I got the Amaze because I was tired of playing with my old HD2 and having to work around bugs and possibly not receiving calls. So far, I'm not happy that the radio seems to quit responding all together and leaves me without a phone (minus the wifi calling but I'm not always around a hotspot).
I also experienced a dramatic signal loss at home, going from full signal strength to maybe one bar right around the time that I first had issues. I don't know if this is related or if this is a completely different thing.
I am 99% sure this is an error with the phone - probably software related with the radio driver(s) or radio firmware. I guess I will try taking it back to T-mobile and seeing if they could exchange it for a new one. I was just really wanting to avoid that as I finally got my phone setup how I like it. Again, Thank you for the input and let me know if you are having the same problem or if you know of a solution.
I am on my third Amaze and also tried a Galaxy SII X due to the same problem at my home. Even the Samsung did the same thing. In my house and especially in the driveway, the signal varies wildly between -85dbm to as low as -111dbm. The frustrating thing is once it loses the signal, it doesn't seem to reacquire it without a reboot.
I'm with Telus, and they said they will check on it, but I'm not holding my breath. In my immediate area, outside my house, the signal isn't great, but it will usually hang on. I have been to different cities, and all has been well with it. Coming from a rock steady 2G Touch Pro II, I am disappointed as well..
I am new here to this site, but I am having a similar problem with my Amaze. At work I always have a weak 4G signal, but the last few days it has been gone altogether. I have full phone service (4 bars) but no data. The 4G indicates I have signal, but I can't connect to anything on the web. I called HTC and they had me pull my battery and sim card so they could send a "reset signal" to my phone. After my phone came back up I had faster service than ever, but it only lasted a few minutes and went away again. I am thinking this is a phone issue. Oh, the Amaze is my first Android. My only previous smartphone was my Nokia E71x.
I know if I have WiFi calling selected, an x will show up on my signal if i turn WiFi on. I've personally only had slow data in the area I work. I blame it on the fact that it is a busy corporate park with lots of hotels, cuz my signal is fine elsewhere. Try calling tmobile and seeing if they have known tower issues in your area. I know I had that problem with sprint and they sent me a free airave. Maybe tmobile could do something similar if its.a known problem.

It's most likely a network issue. I get the same thing, it will timeout/refresh the network where it will not get a signal for about 30 seconds a few times per day. I blame the network, since the same thing happened to me with my mt4g

Thank you! This fixed it for me. It was happening only today while I had WiFi enabled, it would turn the mobile radio off completely and the box would be grayed out so I was unable to turn it back on. I had my sim updated today to enable wifi calling so after I read your post, I turned the wifi calling off and the mobile radio signal came back immediately. Strange bug.

I was told It's by design. It saved battery life by not constantly searching for a mobile network it won't use (due to wifi calling). It's not like you can hand off the call to the local network. I do notice that if i start walking outside, once my wifi hits a low signal it logs back on the network.

There is actually an option to specify how the WIFI calling works: either all the time or only when cellular signal is gone. Sounds like you have it set to be on all the time. This means that if you have a good WIFI connection, the cellular radio is shut off and all traffic goes through the WIFI calling app. The other option (which I use) only uses wifi calling when there is no cellular signal.
I have lost cellular signal 3 additional times since my last post. Its not just that I'm in a bad spot and I have no signal for 30 seconds. This goes on for 30 minutes or more - up to several hours. I have found that rebooting the phone fixes it as I believe it completely (as much as possible) removes power from the radio and requires it to be completely re-initiated during the reboot. Simply shutting it off doesn't work as the quickboot is enabled and most likely doesn't perform a complete re-initialization of the radio. My only guess at this point is that there is some kind of possible leftover code from development which never was removed from the radio (this happens more times than not). It could be a timeout or simply causing the radio to hang because of 1. excessive heat generation, 2. excessive power drain, 3. buffer overflow, 4. excessive RF transmit power... In any case, one of those issues could trigger an event in the radio to cause it to simply stop responding.
I am in the process of trying to get T-Mobile to get me a new phone as I am outside of the 30-day window. I have also confirmed it with them that this was not a tower issue.
Thanks

Hmmmm who is dear? Lol.... Ne ways, well first off, I commend you for digging this thread up rather than just starting a new thread without even looking first :thumbup::thumbup::thumbup: I can't say I've ever seen someone who hasn't even been a member for 1 full day do that. Shoot, I see senior members start new threads or pointless threads without searching first, so good job haha.
Ok, back on topic now, if it's only dropping when you go in your room, then I don't think it's anything wrong with the phone. Not sure who your provider is, but u may be able to call them and have them look up your address and tell you what kind of signal u should get outside your house, and what to expect inside your house. I know t-mobile does at least

Has anyone found a solid solution for this? I was able to pick up a amaze for 50 bucks off of craigslist. But I can't get it to connect to mobile net work. A T-Mobile employee told me to root it, but I'm trying not to cause it's not for me.

Well your situation is a little different than other peoples in this thread if u can't connect al all. Ok wait so first off, it won't connect to a network at all? AND you only paid 50 bucks for it...? Sounds a little fishy to me bud, why did he say he was selling it...?
Next thing, I don't know why a t-mo rep would tell you to root the phone, rooting has no effect on your signal strength or your ability to connect to a network.
And lastly, is the phone a T-Mobile branded amaze owhat carrierr...? and will it not connect at all, period, or can u make calls just not data...?

If the normal connection won't restore after the wiping cash & dalvik cash, you probably have to consider this awesome app:

HTC Titan II drops cellular data connection randomly

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.....
