This JUST started yesterday...
So, yesterday at work I noticed I had no data...so I did the typical restart...still no data...I shrugged it off and went on my way. As I was driving I had data again. I use wifi at home, so when I got home I didnt notice any issues and honestly kinda forgot about it. Well on my way back to work this morning I looked at my phone...had full 4g service...all seemed well. Then I got to my office...
Now let me explain I DO have 4g in this area but honestly...its only a solid 4g outside. Its not the greatest indoors. Well in my office I only get 4g if I'm standing at the window or one "sweet" spot at my desk. So 99% of the time I'm in 3g. Well to make a long story short my 3g antenna seems to be borked. I can pull 4g fine...on lunch today I was in 4g and it was working great. However, when I'm in 3g I get zero data...my phone doesnt work in 3g only 4g.
I called verizon and they just decided to send me a new phone...
I have rooted my phone and I have put the newest radio on. That was awhile ago though. Tonight I'm going to try flashing a different radio but has anyone else had this problem?
Again I get NO 3g service only 4g. In an area where 4g is spotty thats NOT good.
Thanks!
Yes, I had the same issue. The first Nexus I had gave me spotty 4G service and never went to 3G in the couple of weeks I had it. Amazon sent me a replacement which is rock-solid. I get solid 4G coverage where I should (my wife and several coworkers have LTE phones so I know where I should) and when I don't have that 3G kicks right in.
I think you should definitely expected better results with a replacement. Good luck.
I had chosen to use 3G over 4G to save battery life. After about a week with the phone I began to notice that I can hardly ever get 3G reception any more, even though 4G reception has always been excellent. I don't think it is a problem with the phone, but rather Verizon tinkering with its network.
I was having the same problem all day today.
I switch the phone to CDMA during the day and use the office's WiFi for data. However, I noticed today as I dropped my daughter off at school after lunch that I had voice only and no data. Her school is the first tower north of my office that doesn't have an LTE radio, so I normally just get 3G.
Not today.
I drove back to the office and I was able to get data through the LTE radio, but the data connection would go dead as soon as I switched to CDMA. I thought there might be something wrong with the CDMA tower, but two of my co-workers had Thunderbolts set to CDMA only and they were having no problems getting data connections.
I talked with tech support for a good couple hours this afternoon and they had nothing for me. Eventually I flashed the leaked 4.0.3 radios and CDMA magically started working again.
Did the new radios fixed the problem, or is it just a coincidence?
Hmmm...
I have been having the same issue since yesterday. Verizon said there is no outages in the area. I had no data all the way home from CT to NY and finally when I got home at night 4G worked. 4G was working in and out on my way in so I forced CDMA to see if that worked and I have been unable to get anything since. I have a new SIM coming today, but somehow I do not think that will solve the issue.
I've noticed this too. I was turning my LTE off thinking it would use 3g, but I'm noticing now that many times I either have 4g or no data at all.

I'm having the exact same problems and registered here to see what the resolution is. I'm apprehensive to root as I am still within the 15 day return window and quite frankly for 300$ I think this is total BS. Never had a dropped call, missed or unsent text on the 3g network on my old Dinc and I've lived in the same place for 2 years.
OP- could you keep this updated on how your new device works out?
same exact thing happened to me. I'm already on my second nexus and I didn't want a refurb or to lose root. So I flash android revolution hd , used tb to delete all my apps, and hid all signs of root including deleting su. I took it to Verizon and they gave me a new sim card. It was OK for about a day then started acting up again. So I called them from my wife's phone and they had to reset my number to the network and its been fine since

What do you mean by reset your number to your network? Never heard that term before
I'm not exactly sure, some techs don't know about it. When I had my charge it had no data. So they reset my number and phone to the network and I immediately got data back

My gsiii for some odd reason loses 4G and sometimes even service. Last night when i was on a call, it dropped and the signal reflected that i was running on edge then it switched to someting that said "G." I looked at my brother's siii and he was also on edge. So i tried putting it on airplane mode however it would not go through. It's as if i never pressed anything. So i had to restart the phone and it was on airplane mode, so i took it off then about a minute and a half later i got 4G back. Today when i was browsing the web, i randomly lost 4G again but this time i continued to have signal just no data. About a minute later I got it back. About a minute later i lost it again and regained it about a minute later. I havent noticed anything else about the phone and ive had it for about a week and last night was the first time that i restarted it. Any ideas? Has anyone else experienced this? Thanks!
I'm also having the same problem it just happened to me today also and happened the other day when I restarted phone it did nothing then I did airplane mode that didn't do anything so I clicked the enable packet data off then on an item came back in hoping it's not going to be a hardware problem cause I've dropped calls for no reason and had no service or bars were showing but had no edge 4G etc

Yeah it's really weird, when I was using mt4g, it would do that randomly as well, I'm not sure if it's a phone or a network issue. Anyone else experiencing this random drop in data?
Same here I think it's a common issue with tmobile devices.

I just moved from Sprint to Tmo and I'm getting the same on my S3. It would look like i have good 4g coverage with 3 bars then all of a sudden it goes to Edge. So I have to wait for it to go back to 4g to start surfing. Edge is like 15kbps for me which is not even modem speed which is 56k. If I accidentally start surfing on Edge it seems to wanna stick to Edge until I close whats using data then it will eventually go to 4g. But when I get 4g its awesome and I get over between 6meg to 12 but only 40% of the time. I called Tmo and they said I have great 4g coverage where I'm at....ya sure.

I've only experienced outright loss of signal once, which was last night. So far nothing else has happened really. It was just odd that my phone won't even go into airplane mode until I rebooted the device.
Same thing happened to me. I was actually quite worried and about to send my phone back. Everything seems to be working okay now. No issues.

this has driven me mad for the past few days. recently I upgraded to a S3 and my dad got a S 4G (which was released 2 years ago). while we were in Costco, my S3 randomly switched to Edge while the S 4G has 4G all the time. ALso we were on vacation to San Francisco so I could experience "Tmo largest 4G network." While we were in a hotel in Fremont, my S3 again switched to Edge and back to 4G randomly while the S 4G had 4G. also the signal is not stable at all. sometimes(1 or 2 times) it even dropped to zero bar. SOMETHING wrong with samsung phones. I read somewhere someone had this issue with the S2 also. I can live with the HSPA+ for 2 years, but hey dont give me random Edge like that
I plan to go exchange for a new phone at Costco... probably a new S3 to see if the issue still exists...

T-Mobile's 4G network works in a interesting way (do all HSPA+ networks work this way?). They idle in UMTS mode (3G) until there is network activity, and then switch to HSPA+ (4G) mode. The network changing is an automatic thing does to save battery life ("Cellular standby" is often the largest battery drains).
Ever use an AOSP-based ROM (i.e. Cyanogenmod)? You'll sometimes see the network indicator in the status bar switch between 3G to H+ to 4G, etc as you use it. Stock T-Mobile ROMs are hard-coded to always say "4G", but if you go to Settings → About phone → Status, you can watch the network type there change as well as the phone does anything over the cellular network.
You should never be dropping to GPRS or EDGE. Perhaps the mechanism described is defective on your phone?
Happened again today. Had signal but no 4G, not even Edge, just bars. i think it happens whenever the signals low. Thoughts?
I'm having the same issue at my work place. I'm getting Edge (50-80%) more often at my desk, when previously with my SGS2 it stayed at 4G all the time. Checking Cellstandby I am getting 31% time without signal.
Is there a setting to force 4g connection?
My office is in Cupertino, CA and reception is not bad in general, but there are a few locations with 4G dead spots.
I'll check my reception again at home (Santa Clara, CA). I can do a side by side comparison with my SGS2 (now belongs to my wife).
On call with TMO right now, they are going to do a reset of the phone in their system, then I will need to do a reboot. Fingers X'd that things will improve.
BTW, what options do I have to get a replacement phone if I bought mine from Walmart? Do I need to send it in or can I do an instore exchange? Just got it on Sunday. Will I incur any fees if I returned the phone?
---
Reset didn't work. Passed on to level 2, there submitting a service request to check reception in the area. Need to follow-up on Friday if the reception is still bad. Since I'm in Cali I do have 30 days to return the phone.
I have similar reception issue but I dont lose signal completely. I will go from 4g(hspa+) to 3g to edge then it will switch back to 4g after 30secs-60secs. Quite annoying since I will be stationary and it will happen and it happens more when Im in a car. Never had this problem when I had the Nexus One.

Question. With your s2 what happens if you're in an area without 4g? Do you get edge?
Sent from my SGH-T999 using Tapatalk 2
I am having the same issue. I had perfect 4g coverage all over my town, (I live in south texas). The problems started 2 days ago, when I lost all 4g coverage. I took out my sim card and placed it back in and the 4g logo came back on. But now I have been noticing that my cell signal will completely drop and then slowly come back up. This has happened several times. I also went to tmobile and changed my micro sim card and the issue remains. AND NOW I AM ON EDGE!!!!!
Has anyone been able to get a replacement and did it fix the problem?

At first I thought it might have been my rom, but it seems it's happening with my GF's note 2 also.
Coverage we used to receive in some areas is almost completely gone. It will show signal and the 4g symbol but basically have NO internet service whatsoever.
On a better note, we've been receiving coverage in some areas we don't usually have it.
I'm hoping this is just a temporary thing due to the attempts to upgrade towers for LTE.
I don't know if it's because of the UVBMB4 update, but t-mobile service has been pretty crappy lately. Period.
We're in the San Gabriel Valley area.
Link for older UVALL4 modem below, people seem to experience better service

I believe my service has suffered as well. Before the last update that enabled our Lte radios, I had great speeds, now it's slowed Way down. I'm in San Diego CA. Hope that it's just as the Op said, LTE towers being updated and what not.

Definitely have noticed a deterioration of service over the past month here in NYC.
Its because for some reason that new LTE APN is slow on HSPA+.. unless you have LTE in your area switch to the EPC APN. You can find the settings online. Its litter ally consistently a difference of 6+ mbps I have extensively speed tested lol..... click thanks if this helped

I also had problems even with old apn.
Flashed previous radio and service is top notch again.

Same here, I thought it was rom related.
YES! My service has sucked royally for the past month or so. Data latency/hangups/slowness, and the signal will just completely go away sometimes. I noticed that it started as soon as I flashed the most recent radio too, I'm about to go back to the old one.
Count me in, even my regular phone reception went from 4 bars no 1 or 0!
Can anyone point to towards old radio to flash? I go from no signal downstairs to full bars upstairs...theres an obv issue with new radio.
Yup I've noticed this beginning this week I've made zero changes to the phone. I used to get full bars at work and this week it bounces between full and 1 bar regularly. Theure messing with towers for sure

I'm also experiencing significant decrease on data speed. Has your data speed improve after flashing with older radio and APN setting?

I was getting about 9/0.6 and with flashing back Im getting... 14/2 Though Ive been on HSDPA 15 & 21. Though Im not getting 4G as much, but it was sporadic anyways and I lost signal...and now I am not. So, Im happy now even though I am on 3G. However... in my corner big red has same problems as they wanted to not have tons of towers in this corner and theres only a ATT Tower....for a decent distance. basically reception fringe. though I am a new subscriber so i haven't experienced normal TMO, I literally got my device yesterday around 6pmish but it def wasn't normal and flashing previous radio did fix it like it solved everyone elses issue

my problems started last friday. i have limited to no service at all; no data, no voice, even no signal at times (circle with line through it, not just no bars). when i do get a signal, the phone refuses to register on the network. when im at home, i have intermittent service. i miss calls, texts wont send, if i do get a working call, it drops after a bit. there are times when it works fine, even on LTE but it never last long. went to the tmo store last night and they gave me a new sim which didnt do squat. already done the factory reset option (twice). phone has never been rooted, all stock. im in the KC metro so not like in the middle of nowhere. they said my next step is a warranty replacement phone if the sim didnt help. not sure if my problem is at all related to everyone elses in this thread, but yeah, service has sucked.
One of the issues, especially if you switch from 4g to edge to gprs a lot, is a setting in the new modem.
It's something called acquisition order. It has 3 settings:automatic, gsm_umts, umts_gsm. In short it tells the phone what kind of network to prefer. It will search for and use that type of network first.
Prior to the latest update it was set to auto. Now it is set to prefer umts. For some reason this has caused an issue I've come to call phantom 4g. Where it'll say 4g with no bars and no data service.
That is my guess. I'll look into it further.

Thanks guys for the heads up on switching to an older radio, I dont have LTE in Miami yet and was having slow internet for the last 3 weeks, I just switched and wow! What a difference. I'm also using the Epic APN.
I also noticed that speeds were degraded after the update. However, there is a simply fix to make your web a tad bit faster....
Go into your network settings, and switch your mobile network from LTE/4g/3g/2g to just 4G/3g/2g
your device will stop looking for an LTE connection and will just utilize HSPA+
Made a world of a difference on my own device. Connecting to the play store, opening web pages, everything was right back to where it was before the update.
Obviously if you live in an LTE area, there is no need to do this...

So I'm gonna be a noob here for a sec. When people say they are flashing the previous radio (I'm referencing the link that was posted) are people just flashing the modem from the section under the most recent? (the one with the January date on it). Just thought I would ask. Better safe than sorry. Thanks!

Yup, radio is synonymous with modem in this case. UVALL4 is the previous version.
Hastily spouted for your befuddlement
Hey everyone!
I have a stock M8 with T-Mobile and I live in LA. I'm new to T-Mobile so I wanted to ask if this is normal.
My phone will lose data connectivity but the 4G LTE sign will stay on. Spotify will stop playing, Speedtest won't work, but the phone keeps telling me I have 4G LTE.
This happens a lot especially when driving, but today it happened while I was in the drive-through of a fast food place. I had barely moved and yet data was working fine at first, then suddenly "poof" nothing works anymore cause no internet, but the phone insists I have 4G LTE.
Usually turning data off and then on fixes it but not always.
Could it be an issue of switching towers? But then wouldn't my signal drop completely? Why does only data stop?
Anyone else having this issue or do I have a lemon phone I should return?
if you are jumping from tower to tower it may not relay properly. Call tmo and tell them to do a signal refresh. call from a different phone.
Do you have power saving mode on? The reason I ask this is bc it will turn your data connection off when your screen locks.

Same here ,
Ever since I bought the m8 it happens to me time to time.
Ive tried dis n reconnect the mobile data or go on airplain mode, but sometimes reboot is quicker.
Hope HTC publish a bug fixed firmware soon
Its a provisioning issue on the towers people you need to call tmo...
This was happening all the time to me on my Note 3 which Is why I upgraded to the M8. Just got it last night and it's happened once. Also, the signal isn't as strong. My Note would hold a lte connection with barely 1 bar. The m8 not so much. Likes to switch between 2g, 4g and lte.

It was fine for a couple of days. Today however I had to wait in the car for 1.5 hours for something and was playing Spotify.
Didn't move for that entire period. For an hour it worked fine, then suddenly it did this again where it wasn't receiving data and yet the 4G LTE sign was on screen.
So I guess it didn't really help. I turned data off and on and it restored it, but still... that's not cool.

Yeah same here. It happens in my house when I'm using my phone in bed and just loses data but it still says LTE and have to either turn off and on data or reset my phone.
Also on my way to work today I was using Spotify the entire drive, which is about 45 minutes, and never lost data but on the way back it lost it about twice. It sucks and hopefully there's a fix of some sort.

tmobile signal issue
my z1 and htc m8 sometime both have this kind of issue
they both show I still have lte icon but just can't connect to network
and sometime you must wait like 1-2 mins to reconnect to network
I have had my M8 for a week and have not experienced any issue with data loss. I am in Miami, Fl. If anything I get way better LTE speeds than I have had with any of my last phones( S4, G2, Iphone 5S)
Same issue with my M8.
Full bars LTE signal and sometimes data just stops working. Need to reboot the phone to get it working again. Was thinking about exchanging the phone but it seems like a software glitch...

I don't have this issue but I do have terrible speeds in south Atlanta.
3-5 bars in my home, and download speeds are from 3-6 Mbps down and uplad from 2-3Mbps up even with LTE. I get much better performance on HSPA+
LTE pings are half that of HSPA though
Just to add on here, in my experience this has more to do with the area and likely the towers supporting that area then software or hardware. Another possibility is T Mobile's network in LA is not 100% compatible with HTC is new radio firmware yet. If that's the case some tweaking by t-mobile on the backend would fix this issue straight away.
The reason I say this is because in Las Vegas, Nevada I never have any problem with LTE losing connection, however, this last week I was in Long Beach, CA (LA County) and constantly had loss of data connection while the phone would still displaying a full 5 bar 4G LTE connection.
Reboot or switching to airplane mode would fix it, however, it got to be so bad and happened so regularly, I eventually stopped using LTE entirely while there. The HSPA+ "4G" connection there was still producing around 10 megabits per second download which was more than enough. So, while there I switched off LTE and had no more issues with data connection dropping.
Long story short clearly seems to be an issue with T Mobile Lte Towers in the greater Los Angeles area. Possibly its an issue in other areas as well.

Happening here in South Houston too, but i am using a VZW M8 with Tmo.
I also have this issue, but I'm on AT&T and missing some bands that I need, so I was figuring it was that.
I had a galaxy s5 and had same issue.
So i know it's not the phone

Has anyone found a solution to this problem yet? My HTC One M8 has been losing data connectivity ever since I purchased it last month. It will say I have 4G LTE but I will loose data connection regardless. It's a nuisance. I never had that problem with the M7. My camera on the M7 got a purple haze so T-Mobile replaced it with a refurbished M7. It was the worst thing I could've done. The refurbished M7 would freeze and reboot a lot, until it finally got stuck in a boot loop and I lost all my photos, videos, and files. Would not go into recovery. Then T-Mobile sent me a plastic Samsung S4 as a replacement for that because they were out of the M7. The new M8 has been working pretty well except for the annoying data connection loss everyday. I have to activate then deactivate airplane mode to obtain data connection again. Only other time I ever had this happen was with a certain nighyly rom I put on my HTC HD2, but that was rooted, this is a stock phone, I never expected to have a data connection problem with a stock rom.
I had this problem for ages with straight talk with my old phone just before I bought my M8. Exactly the same issue in that my data would seemingly just cut out randomly after a bit then come back later(switching off/on and/or in and out of airplane would restore it).
In my case, it turned out to be my data settings. I played around with different settings one night and found that different settings finally got rid of the problem for me. Your mileage may vary, but it's an easy enough thing to try.
Well, at first I thought my phone was just getting terrible service when I went to Ohio for work, but then I got random texts from 2 people wondering who I was, because I'm assuming they got a text somehow from my number.
It's constantly Searching for Service, getting no data, or if I'm lucky it will be on 3G for a little bit, but I have yet to see LTE even when 5 days prior I was getting great signal.
I already restored to a backup on the same ROM, but the problem still persists.
Whats the best plan of action? I'm stumped. Should I just reset it to factory settings, if so, what would be the best way to do so considering my firmware is updated?
So you never sent any sms to those people? I don't know on CDMA but GSM Sims can be copied pretty easily by someone with bad intentions and radio towers accepts both sims. It could be an error from sprint. These are strange happenings
