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
As some of you have probably read.
I gave up on the M9, mostly prompted by dropped calls, or calls going straight to voice mail.
I had the M9 replaced and gave it to my wife. It's been near perfect for her, she even dunked it and it's still running great.
My G4 is now doing the SAME thing. Although it has not dropped many calls, tons of calls go straight to voice mail.
Had a very important call this morning and even shutoff LTE, WIFI and Bluetooth and only had 3G on. And it went to voice mail.
The signal is not great, but should be fine for CDMA. Previous generation phones were fine (M8,M7, etc.)
I do see the signal bounce. Where it will be 3-4 bars one minute and none the next. The bouncing can be common in weak LTE (which is definitely weak).
But it's even bouncing with LTE off.
Even at home with two phones in the same location.
My wifes M9 will work, but my G4 will go to voice mail.
Where a couple months ago at home
My wifes M8 will work, but my M9 will go to voice mail.
Could their be something on the account that limits my phones? Like wrong bands or something. Not enabled for Spark but on a Spark Network.
As soon as Verizon gets the LG V10, I'm 99% sure I'm gonna switch. Don't know what else to do.
I don't really care for how locked down Verizon is, but I need a working phone.
This problem happens at multiple locations.
Any ideas appreciated.
I know this isn't specifically an M9 issue, but I know their are more experienced folks around here that might know something.
It is related to M9 TYPE phones though (Spark Generation 2-ish phones). It started when I switched from M8 to M9.
Upgrading my wife from M7 to M8 went fine and from M8 to M9 went fine.
Upgrading me from M8 to M9 went south and from M9 to G4 went south.
All SIM cards cam with respective phones.
All bought new.
All S-Off and/or rooted.
I may have found the answer. Read this !! It has to do with having WIFI on and phone going to sleep. Which is exactly what happens on G4 and M9.

I disagree...I'm using the opposite settings that he is saying to use & I've never had this issue (that I know of). I don't make alot of outgoing calls...most are incoming...I also have my work cell fwd'd to my M9 so I don't have to carry 2 devices...I'm on Wifi a majority of the time, I get calls & texts all the time w/ no issues...the only thing I have checked in Advanced WiFi is Wifi Optimization, Keep Wifi on during sleep set to always
Fix
------
The fix is to not have Wifi on when the phone is idle/sleep. change your Wifi settings below to the screenshot below.
Settings -- > Wifi -- > MORE -- > Advanced -- > "Keep Wi-Fi on during Sleep = Never"
I also have "Network notification" and "Always allow scanning" enabled.

Sprint did (in my opinion) a very poor job with how it handles calls. One of my favorite phones was the evo LTE which not only could do LTE and a call at the same time but if you weren't in 4G it could do SV-DO and work on 3G which it actually worked very well. Especially at the time when I had that phone, I hardly had 4G anywhere so being able to use data at the same time on 3G was great.
That said, that feature didn't stick around long. The m7 had a separate radio for LTE & 1X meaning you could surf at the same time because it had separate radios. This couldn't do 3G which was a step backwards however 4G was becoming more mature.
Fast forward to today and with your modern tri-band device while it supports multiple bands that the previous phones didn't, most people have no idea what that means they usually assuming if it's a 4G phone well then it's just that how is any different.
I have had plenty of people complain to me about calls going straight to voicemail or signal issues. Rather than having separate radios, Sprint just uses CSFB Circuit Switched fallback so when a call comes in, it lets the phone know via LTE and immediately switches back to 1X to grab the call. That said it's by no means perfect especially in a bad signal LTE area can cause issues. When I'm at home or work I usually set my phone to CDMA only since I have wi-fi there is no advantage to be on LTE, causes issues with calls coming through and wastes battery. Most users have no idea about what is actually going on so it's hard to explain to a friend why when a caller calls them, the caller might here 5-6 rings before the phone even goes off. Sprint's LTE signal frankly sucks in most places I go, even right next to the tower sometimes you won't get full signal.
Anyway if your wifes phone works fine in the same spot as your G and you are doing all your testing off of LTE and still having issues that tells me either you have a bad radio again or something is provisioned wrong. I would put the phone back to stock, reset the radio and reactive the phone then do some testing with calls off LTE again. If you still have issues at the point, I would swap the phone. My M9 is pretty good with CSFB, I haven't had too many issues with it but really I think it's a very poor solution how it works especially when your in a fridge LTE area with the phone bouncing in and out of LTE.
Once the network goes all LTE (god knows how long that will take) I think this will be a thing of the past but for now CSFB now it's here to stay. I don't see Sprint ever going back to separate radios like the previous gen phones as they would more likely be focused on voice over LTE instead.

It has not failed in 5 days since I flipped it.
It may depend on the WIFI it's on, IPV6 etc. I don't know.
I think this may have started the same time MMS started failing for SOME folks if WIFI was enabled. Disabling IPV6 on WIFI was a work around (which is disabled on your ROM).
But not everyone had this issue and depended on their router.
So their is weird sh$t happening due to Android changes.
I think this issue is related and not everyone runs into it.
I have had WIFI Calling setup, but disabled it on both M9 and G4 (because it's extremely unstable on every phone I've tried).
Not sure if that is part of it. Like my account knows it's WIFI Calling capable. But my wifes never had WIFI Calling setup, she also does not run WIFI at work. She's never had the problem (even with the same phone I had problems with).
Again I don't know the exact details, and this is not a fix. But disabling WIFI when asleep seems to have stopped it problem. But I need to go a bit longer to be 100% sure.
I've seen similar threads on many phones and carriers and many start off saying "Problem started with 5.x.x OTA update".
I think I was close when I thought it was the optimizer. And before I found that thread, I was testing with WIFI completely off (which also worked).
Something is a miss and there may be more "options" to cause the issue.

I would put the phone back to stock, reset the radio and reactive the phone then do some testing with calls off LTE again. If you still have issues at the point, I would swap the phone. My M9 is pretty good with CSFB, I haven't had too many issues with it but really I think it's a very poor solution how it works especially when your in a fridge LTE area with the phone bouncing in and out of LTE.
Once the network goes all LTE (god knows how long that will take) I think this will be a thing of the past but for now CSFB now it's here to stay. I don't see Sprint ever going back to separate radios like the previous gen phones as they would more likely be focused on voice over LTE instead.

I know about the call switching for LTE and it sucks. But that was not it. I tried CDMA only and it did not fix it.
Disabling WIFI while sleeping is still working. Not one call has gone to voice mail at work in over a week. It used to happen 2-3 times a day.
I HATE disabling wifi while asleep though. I'd like to still get to the bottom of it.
I think some how it is doing something over WIFI when a call comes in, if WIFI is available. But when the WIFI is in power save mode something gets messed up.
The problem started on OMJ's ROM with IPV6 disabled. So it's not that.
The only thing common is Lollipop, Sprint and my WIFI locations (and a modern single radio triband phone).
I'd like to try getting "WIFI Calling" capability off my account. I think once you set it up once, it's enabled automatically on my account.
I will also say, if I do enable WIFI Calling, it's terribly unreliable. Maybe that's a hint.
The WIFI signal is solid and no issues using WIFI itself.

Having Wi-Fi calling provisioned on your account is just that, it just means if you enable wi-fi calling that your phone has the green light to connect and move forward with the server. That said if you keep wi-fi calling off the fact that it is still provisioned on the account doesn't affect anything at all if the service is not active.
If you only solution is disabling wi-fi while sleeping something in the rom is borked. Return the phone to 100% stock, hard reset it (including the radio) then try using it again. While again CSFB isn't perfect, if the phone is CDMA only you just shouldn't be having this kind of issue. If your not having issues with other phones in the same area with calls going to vm, you know it's not the network and something with the phone. If it does this on 100% stock after a re provision then you have a borked radio and the phone should be swapped. Which I have seen borked radios before, the wi-fi radio in the phone is totally separate from the CDMA/LTE radio.

Did that, returned to stock, same issue. Got Another M9, same issue, got a LG G4 same issue. Just signed up for T-Mobile (have not canceled Sprint yet). Two LG V10's. T-Mobile just announced a huge expansion on their network to cover areas that I needed with LTE (Sprint roams 1x Lakes Region and North in NH).

Not a bad play, Sprint's Network has come along way in the past few years but with CSFB and a crappy LTE signal is most places they still have a lot of work to do. One of the reasons I stay is my plan and they are pretty friendly towards rooting/unlocking for the most part.

The V10 was awesome. T-Mobile was extremely good at My work, My wifes work, Home and all places between. Speeds were 4-8x faster (seriously) than Sprint. Simultaneous Voice and Data VoLTE.
But what the map showed up in NH, didn't match reality at all. Sprint is pretty dismal too, but they at least Roam and you can get 1x or 3G from either US Cellar or Verizon.
But T-Mobile had nothing in the areas Sprints Roams. So I'm sticking with Sprint for now.
I've concluded it's a combination of weak locations, the requirement to switch from LTE to CDMA for calls, and something around that is complicated by WIFI while asleep. Shutting off WIFI or shutting it off while asleep definitely improved things but didn't eliminate it completely. Both phones (M9 and G4) are Qualcomm chips and probably have similar Radio Firmware. But it's overly complicated due to Sprint being a bit behind the ball with VoLTE.
I agree Sprint is not quite so tight on locking things down. T-Mobile is the least locked down, then Sprint, then AT&T then Verizon. I know Verizon would perform flawlessly. But the combination of expense and being so locked down keeps me away. T-Mobile price was really good 2 lines 10GB each, with Carry Over and free Music/Video streaming. And the V10 already had TWRP on day one. The G4 on Sprint does not have TWRP and probably never will. It is rootable, barely.
I convinced my Sister to switch to T-Mobile because she wanted an iPhone and I recommended she not Jail Break it. But she wanted Tether (I was rooting Androids on Sprint for her). She is very happy with T-Mobile. And she generally stays in Eastern MA.
We'll see what HTC does this next time around. But they really need to step up their game. The reception issue really isn't an "HTC" issue. It's a Qualcomm/Sprint issue in my opinion. It's a kludge and I think Sprint is the only one with this kludge.
THE TL;DR
Verizon data in a specific area used to be solid, but now is practically nonexistent. I know it’s not gone entirely though, because I can maintain an LTE signal lock and use it if I exit the affected area, get an LTE signal lock, start the utorrent and begin downloading a [legal] torrent, and then re-enter the affected area. I’ve tested with friends, family and strangers over a series of devices - it’s not just me. Verizon says it’s heavy network usage which seems like BS. Please help.
THE FULL VERSION
THE PROBLEM
About a month ago the Verizon data service in the area that I live/work went from solid to almost nonexistent. The affected area is maybe a 2 to 3 mile circle it seems. I’ve had friends, family, and even strangers verify that it isn’t just me - they’re experiencing the same thing (wide range of devices.) Essentially, I can no longer get LTE in this area, and the 3G and 1x are even spotty (and horribly slow.) Veeery occasionally I will be able to get LTE to lock, but it drops almost immediately. Calling and SMS do not seem to be affected. Outside of this affected area, LTE service in the area seems to be unchanged. I’ve opened multiple tickets with Verizon -- they essentially told me that the network in my particular area is overloaded and this can’t be resolved until they build a new tower that covers the area (obviously that’s not going to happen anytime soon.) Although this might seem plausible, I’ve lived and worked in this exact location for the past 3 years, and only once has something similar happened previously (and I’d know because I’m a power user who doesn’t use a computer, and who uses LTE for internet exclusively.) The previous occurrence was in February this year, and the issue disappeared after about a week.
I do happen to live in a college town, so the network could be under some additional strain with the kids coming back, but I don’t believe admission is up appreciably from previous years, and I don’t know of any new living spaces that were built in the area that’s affected, so it seems that the network shouldn’t any more strained than it has been in previous years.
THE UTORRENT TRICK
If I move outside of the affected area and get an LTE signal lock, open utorrent, start downloading a torrent [legal only,] and then re-enter the affected area, the LTE lock will hold an I’ll be able to get the full LTE speeds almost as if the problem has been resolved. However, if I shut off utorrent, or if I toggle airplane mode while I’m in the affected area, the LTE signal lock is lost, and issue will persist (ie. I’ll only get 3G, 1x, or nothing at all.)
QUESTIONS
Can anyone explain what might be happening and why? Is it really that the network is under heavy load?
Why won’t my phone even find LTE while I’m in the affected area? It’s clearly still available if I can keep an LTE lock using the utorrent trick.
What causes the utorrent trick to work? It almost seems like the trick bypasses the network’s attempts to hide LTE from me in this particular area.
I’m rooted. Is there any way that I can force my phone to find and lock the LTE in the affected area? The 3G and 1x are essential unusable.
If I can’t force my phone to lock the LTE and stay on it, is there some other way to make my phone hold the signal once it has it *besides* using the utorrent trick?
Any insight would be much appreciated.
Is anyone else experiencing hang ups when using mobile data? Every so often (multiple times throughout the day) data stops coming in and I see the upload arrow on the LTE but no apps or data respond until I flip on airplane mode and back off. It's been happening every day for over a week and factory reset didn't help.
Happened to me a few times but not super frequent. It was random and I figured it was verizon data service and not the phone. I didn't see any downtime for vzw online though so I dunno. There's a security update and maybe that'll fix the bug if it is one as well.
I've noticed this as well.
I mostly get it when I launch the Google Search/Assistant app. I can verify it immediately because it's not listening for my voice input. Another way to tell is that the newsfeed that Google usually loads doesn't appear, nor does it attempt to auto complete any searches I perform. I haven't had to cycle my Data or WiFi on/off to get it to work, I usually just kill the app from the Recents screen and relaunch it, whereupon it launches and performs normally.
I have noticed the same thing when it comes to my google feed/google app.
Just happened again and it's pretty annoying. Can't figure what's causing it. I noticed Pandora wouldn't play and then tried to open my Google feed and nothing. Tried YouTube and a few other apps and still nothing. Did a reboot and all is good. Will try and toggle data off and on next time
Still happening. Randomly when browsing things won't load and I'll notice the LTE upload arrow and nothing works until I toggle airplane mode. Starting to get on my nerves.
Good to know it wasn't just me.
I'm all the way in Korea so I can tell you if can't be the network provider at fault here. Also the immediate recovery after toggling airplane mode and back also points to this problem being a device issue.
This is quite irritating...
Quick update: after a factory reset the phone still hangs randomly on 4G up data until toggled off.
Hopefully the last update. Switched sim cards and it seemed to solve the issue. Been running 4G data instead of WiFi for the past two days without hiccups. May have been an issue when switching the card from my 6P.
I had random glitches with the data too. I noticed it has pretty weak RF performance compared to Moto Z and S7 Edge on verizon. I haven't tested S8 yet (waiting for unlocked)
Phone tricked me. Issues persist after new sim card. Now comes the battle of refurbished phones.
FWIW, I can't see any difference in RF performance good or bad vs my old HTC One M8. In good spots, service is still good. And in bad spots, it's still bad.
Well, service is great when it works. I assumed it was network prioritization but it happens even on a New billing cycle.
I replaced the sim card, reset the phone, used safe mode, and just got all brand new G6 in the mail. Same issue and Verizon doesnt know why. At this point it has to be a network issue.
As an interesting side note, I used my 6P all day with no issues this past weekend

I've had a similar issue recently, a few times. Sometimes the phone will say no network connection in certain apps, other times it just does not work, LTE arrows blinking, but no data, apps do not respond. However, it would not work after toggling airplane mode, so I rebooted. Oddly, when this happened, my wife opened the same app on her G6, and it worked (we were not on wifi). Not sure if it's a network issue, or not. I'm gonna try a factory reset and see if that corrects this. I've had the device for 10 days, has happened 3 times.
I had a similar issue 2 days ago; no Verizon internet when trying to use my Chamberlain garage door opener app. I got it to work again when switching networks from Global to LTE/CDMA and back to Global. After that I rebooted the phone, got off wifi to make sure Verizon data works. Haven't had a problem since.
Another update but I'm sure no one cares any more. Used my 6P all last week with no issues. Back on my G6 today and data freezing throughout the day. Verizon doesn't believe me and no one knows what to do. I'm SOL and this G6 is to blame.
My girlfriend and I have both bought 2 brand g6s. Within 30days of owning, all of the issue that have been presented on here have happened and continue to happen even after joining a different verizon network plan. We have not figured out a fix and these are BRAND NEW. Not refurbished phones
Guys,
I need some help, I have an S21U (unlocked) from Samsung. Since launch day, I've had no problems with it. I was with Verizon, then had to move to TMo because of coverage at work. I noticed I started losing signal, like dropping completely, showing the no service circle with a slash, which would immediately be followed by full bars. When on a call, the call drops. This happens over and over, making the phone unusable as a phone.
Thinking it was TMo, I switched back to Verizon. Same thing. I've scoured the web, and there are posts out there describing the same issue, but no resolution. So far, I've tried:
-swapping for a new SIM card
-resetting the network settings
-switching carriers
-using app to manually select LTE over 5G (more on that below)
I've read people hard resetting, with no success. Other than selling or return the phone for a carrier-branded device, I don't know what else to do. I think the timing of the problem and my switch to Tmo was coincidental. It SEEMS when the device switches from 5G to LTE I lost all service. But I haven't stared at the screen to be able to confirm that. I've also seen it flipping from LTE to LTE+ to 5G. But when it drop, it drops hard, and I am one of the 6% of people who still need a phone to be a phone.
Any ideas or suggestions? Returning for "service" through Samsung seems like a nightmare, and the local Samsung repair place said all they will do is re-flash the device.
Thanks!
Tmobile is horrible where I am too. I'm a sprint customer and they are steering me to their crap network.
Use routines to set up a button to run 4g lte mode only
5g is very problematic for me and lte works consistently.
I think 5g is still in it's infancy and not worth the extra power usage even when it's a bit faster in good service areas.

Thanks. It's not TMo, I switched back to Verizon, same issue. So it's definitely the phone. I did try and select LTE only, it didn't matter. Same problem.

I'm having same issues. However I've always been on Tmobile but I literally have no service at my home or work so pretty much all day. On top of that the wifi calling hardly works so making calls is useless. It drops right as it starts ringing lol. I'm pretty sure my issue is a tmobile issue.
