Where'd my 3G/4G go? - Thunderbolt Q&A, Help & Troubleshooting

Just got my replacement TB about a week and a half ago(long story), but all of the sudden after having it work perfectly for several days, I have no 3G/4G signal at all and barely even have 1x connect. Spoke to a "4G expert" at tech support and he had no idea and recommended I do a factory reset. I did...again, and it didn't help. Any ideas here before i make Verizon send me another phone? And before you ask, I'm not rooted, my back cover is securely on, and I've pulled SIM, SD and battery. Thanks.

Sounds like your Sim is dead.

update: I left town and now I have full signal everywhere I go. Called VZW tech support and they say there aren't any known issues in the area but when I get back to call them and they can run some test or another on my phone to try and figure it out. I guess they've got a tower acting up, but it's weird that I'd be the only one having a problem.

I had the exact same thing happen... 3G/4G gone, then it would come back then gone again. This time for good! Spent 90 minutes in a VZW store with them attempting to troubleshoot it and calling everyone they know.
Bottom line, they are sending me a new Tbolt.
While I was there the manager hinted it is more than likely a sim card, they have been seeing a bunch of TBolt's with similar things. To make the issue worse, this store is actively suggesting to customers NOT TO BUY a thunderbolt due to all the issues.

4g works but switching to 3g/1x doesn't seem to

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.

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.

[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.

Did you ever try doing a factory reset? I'm curious to know if that will fix it.

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.

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.....

[Q] I am about to throw this phone!

I had a defective DNA from day 1 without knowing it. My camera wouldn't focus, no matter what I tried, so the store swapped it out for a brand new one (I watched the associate open the box). I want to clarify something up front as well, I NEVER had any problems getting service with my previous DNA. No matter where I was I seemed to have perfect 4G, never dropped signal, no ping problems, no speed problems. Even on 3G it would switch between the 2 just fine with no problems.
This new one I have is apparently incapable of holding a 4G signal. Nor is it capable of doing anything involving the internet for minutes at a time, regardless of having a perfect 4G signal. It will literally sit in Chrome for a minute trying to load a webpage with 3 bars of 4G. Inside a restaurant It was almost useless, trying constantly to switch between LTE and CDMA. I restart the phone all the time thinking that will help, and once in a while it will do the trick. Most of the time restarting does nothing though. I'm at a loss as to why this phone could be acting like this, and I'm asking for some advice. If anyone has any suggestions please let me know, meanwhile I will continue to try different things.
Have you been able to compare the signal at the same spot with another phone?
Send that fanned thing back for a replacement! That's the whole reason I left the s3... Thats not how this phone should be behaving.

That sucks. Maybe a new sim card would help?
First try new sim.
Second if you are rooted, try set dns and use Google dns. Don't know about verizon, but my local providers dns sometimes goes on fritz causing lot of delay in page loading and even fails at times.
Best thing to do is side by side comparison. Try your sim in other phone at verizon store and see if that is acting fine
From my Droid DNA, right in your face....
take it back man get another. we spent too much on these phones to be dealing with issues like that.If your like me your stuck with it for a couple years. It should work as a phone first and foremost. Thats why i got rid of my gnex!
Just so you know, the bars next to the 3G/4G icon is not your data signal. Those bars just represent the basic phone signal for making phone calls..
The bars have nothing to do with data..

Cell connectivity completely drops, then comes back, rinse and repeat

I received my new XA Ultra from Amazon yesterday. Popped in my SIM and started setting it up. It had two software updates out of the box, so I applied them, then started installing apps. I noticed that my cell connectivity would completely drop (no bars), then come back. When I checked in the Access Point settings, the option to discover carriers would appear, then disappear.
I assumed it was some kind of software corruption, so I factory reset, but it continued doing it. I also tried pulling the sim out and putting it back in several times. I can only assume that I somehow got a defective unit or that one of the software updates applied the radio incorrectly. I processed a return with Amazon and have a replacement coming later this week.
I hope Amazon doesn't turn around and resell it through warehouse deals. I have received a few devices from them that they clearly didn't test and I was very explicit in my comments for the return. I'm just hoping that my replacement doesn't exhibit the same issues because I'm not sure what else it could be. It's not my SIM. All of my other phones stay connected to AT&T just fine in the same spot.

Did you check before purchasing that it would connect to I'm guessing by AT&T US network's I know yours are different to ours in the UK. I've not had any problems with my normal xa but I'm in the UK

It's definitely fully compatible. It even downloads the correct APNs, but then they just disappear and the signal drops completely. I get full LTE speeds when it's working and nothing when it's not. I also tested a T-Mobile SIM and, while it holds onto the signal longer, it does the same thing (drops completely).
I plugged the phone into a computer and did a complete software restore, which didn't fix the issue. At this point, I'm sure it's either hardware or a really bad ROM update. I'm hoping it's hardware, because if not, that means that the replacement will have the same issue after applying the software updates to it.
This is my second Sony xa ultra with the same issue here's what happened
Purchases from best buy didn't setup until I got home had 2 update applied them signal drop and reset constantly I figured it was because I have bad reception in my area but the more I looked at the phone I noticed the build quality on the metal bumper wasn't sealed in some areas so I grabbed the packaging and headed back to Best Buy keeping note of the signal issues as I drove there (disconnected from WiFi of course) I noticed the signal did not drop connection at all on the way to Best Buy return the phone and explain to him the issues that I had at home with the signal and also wasn't happy with the build quality defect so I returned it and exchange for another one immediately popped the Sim in it downloaded my APN and I had LTE drove home no drop issues connected to wifi installed the two updates then I drop issue return

The replacement model I received from Amazon did it as well. Right out of the box, before updates, it was dropping the signal. Are you on AT&T?
I watched it really closely. I think I know what's happening. It's not falling back to HSPA. When the LTE is too weak, it simply drops completely until it can reconnect to LTE. If you set it to HSPA only in the mobile networks menu, you will never lose your signal. I tested it with both T-Mobile and AT&T with the same results.
This is a pretty major defect.
You might be on to something, yes I'm also on AT&T.. but I can't find HSPA in mobile network should it be GSM only or LTE (preferred)

It should be something like "GSM/WCDMA Auto" or "WCDMA only". Basically anything without LTE (except CDMA).
I'm honestly just glad to finally have someone else confirm. The chances of having two defective units in a row are extremely slim. Really liked the device otherwise, too, especially for the price.
I tested it for hours. I never got a disconnect on HSPA when I had that set. I just wasn't willing to live with that restriction.
Me as well!! phone is perfect for the price I paid out of pocket I had a BB gift card. I've been shopping for the right phone for a month now I've had about 5 phone from 700 to 200 bucks the expensive ones we're worth the price and the cheaper ones didn't feed my power craving I'm pretty happy with this one for the moment, thanks for the tip
This may be an AT&T SIM related issue.
I have T-Mobile and with my T-Mobile SIM I have no problems. I tried my friend's AT&T SIM, downloaded the APN, rebooted, and sure enough signal drops just like you're experiencing.
I'm having the same exact issue as previous posts with my Ultra. I purchased the unit from best buy the day it came out and using it on AT&T. I love the phone but the issue with completely losing connectivity is a bit annoying. Called customer service and they gave me the same website to fix software issues. Just curious as to why I'll be in same location without movement and then all of a sudden lose my signal.
I have the same problem using cricket wireless which is using att's network, lte signal comes and goes, this is becoming really annoying, is there a fix for this already, or should i return the phone
So I just got off the phone with Sony and they said I would have to send in the phone for repair leaving me with no phone. I've had issues before with phones and the companies just send you a new unit with a box and return label to send back defective unit. The rep said maybe my provider would give me a loaner phone.... Smh Looks like it might be time to leave Sony. Maybe I'll have better luck with the Lenovo Phab Pro 2 coming out next month.
Same issue here, right out of the box today.... Using AT&T reseller and I would have to agree that it is an issue as was mentioned earlier where the phone is somehow not able to fall back on to HSPA on a weak LTE connection so it just completely disconnects. Strange thing is where I am using it (at my desk in my office) I never had an issue of LTE dropping off with other brands of phones. As soon as I left the cell area and started using it at home or at another location further away I had no dropped LTE signals. I think Sony support will be useless unless we can somehow get past the standard support desk. They told me they have no higher support I can be directed to, that I would either just do a software repair (which I assumed correctly would not work) or send it in to service. Not sure what I am going to do at this point, cannot have my phone jumping out of service every 2 minutes during the work day. Any other suggestions would be appreciated.
EDIT: upon further review (using LTE discovery App) it appears that "some" At&t sites are having issues staying connected with LTE band 17 on this phone. I drove up to one of the sites the phone has issues with. It had a solid,strong signal within 1 block of the tower and band 17 still disconnected the radio completely. As soon as it reset and moved to band 4 it stayed on without disconnecting until I moved away from the site far enough for band 17 to kick back in. At that point it continued to disconnect every 1 -2 minutes until I moved the phone mode into HSPA preferred. I don't know what to say about this, band 17 works great on 2 towers within 10 miles of here, but some others and this tower causes the phone to go into a fit. Clearly the phone has LTE issues as any other ATT LTE phone on band 17 I have used in this area has always worked just fine. Anybody have an opinion on this???
I have what I think is the issue, now if we have any way to get this information to anyone who can actually do something about it. I have 2 sites by my home that the phone works flawlessly on LTE... no dropped LTE signal whatsoever. Here is the difference... they are band 17 ONLY sites where the sites my phone is unable to hold a LTE signal when the At&T site is broadcasting both band 4 and 17. That would explain why the rest of the sites around where I work do not maintain a signal either. We need to all contact Sony support and somehow get this information thru to them. The issue is the phone clearly being unable to handle a site broadcasting 4 and 17 which I think is a majority of them.

It's still not falling back in HSPA like it should. If it has difficulty with an LTE connection, it should not drop connectivity completely.

Agreed, but keep in mind that my XE ultra was 1 block from the tower with incredible LTE signal strength and it still completely shut the radio down and restarted. This is not for lack of signal but a complete inability for it to handle a band 17,4 tower. Although it would be great if it just moved into HSPA, that would mean your phone would be in HSPA 80% of the time, even when the LTE signal was completely adequate for the area. This clearly is a defect that makes the phone basically unusable (as it continually shuts the radio on and off) until Sony can figure this out. My concern... there is no way to talk to anyone at Sony that can do anything about this until they get enough support complaints directly related to this issue, this could take months not including the time they need to program an update and fix. Very frustrating.

Frustrated with this as well, hopefully sony fixes this problem more sooner than later
Received an update yesterday and I can't confirm 100% but it appears I haven't had as bad connection (popping in and out). I'm in Houston btw.
I got the update and so far phone has been working fine
The latest updates from sony fixed this issue.. so happy and enjoying it now
