I'm not sure if it's just a faulty device or what. When i first got the phone, I rooted it with success, then the stock weather app and my mobile data started not to work. The problem eventually fixed itself, but it seems to have happened again, out of the blue. I've tried everything from calling MetroPCS, to doing a fresh install, a fresh flash of both a stock and custom ROM. I even tried manually entering the APN information with no luck. The 4G LTE symbol is there, I can make and receive texts and calls and the wifi works with no issues. Could it maybe just need some sort of system update? If anyone out there has had this problem and/or has a solution for it, I'd love if you would share ti with me. I'm getting a little irritated paying for data I can't use.

I think I have a very weird problem with my unlocked AT&T Galaxy Tab. I can send and receive message using my monthly data plan SIM card from AT&T. But the problem is I cannot use this SIM card to access to internet browsing. I tried to configure APN setting following some posts here and I found elsewhere, unfortunately they all didn't work for me. I use Canada Bell I9000 modem band and not sure if this is the reason. I rooted my AT&T Galaxy to unlocked European version.
Thank you
I have the same problem I'm in the US, and I put my att sim in my unlocked international G-Tab, and at first it worked fine but after a while it stopped. But what I don't understand is I can make calls and send text messages but no data. It is rooted using superoneclick I tried fooling with the APN settings as well but nothing.
Hmm maybe this is the problem I ran into as well. I have an AT&T Galaxy Tab, and I flashed it to Overcome, and also tried DXJPE. Using either of those, after adding the Broadband APN, it would work but then the data would randomly stop working.
In order to get it working again, I'd have to do one of: (1) reselect the APN (2) toggle airplane mode or (3) reboot. It didn't always seem consistent which one of those was necessary.
I tried numerous modems and never managed to resolve the issue.
I recently have been trying to return to stock to see if that would solve the issue, but it turns out once you've flashed off of AT&T stock, as far as I can tell you can never truly go back, since we don't have working bootloaders. I've managed to get it back to mostly stock, but with corrupted bootscreens and recovery, but apparently everything working once booted, and I haven't seen these problems with the APN since then. However, the problem was so random it's hard to know if it's gone for sure.
Does this sound like the same problem?
Hi
Can anyone shed some light. My SGN suddenly lost the ability to make phone calls ('Mobile Network Not Available' message), cannot connect to wireless network and cannot connect to mobile data. I rooted it about a week ago and it has been fine up until now.
I tried unrooting, re-rooting, re-flashing current firmware (LA6) and reflashing just the radio (LA4). All processes were successful but didn't fix the issue. I tried a different SIM, but no dice!
Is there anything else I should try? Does it look like I have a hardware problem?
Thanks.
Further info - switching to GSM Only has restored mobile internet and wireless network connection (?????? WTF???) BUT cannot make a phone call.
Help please.
Sort of the same problem over here, only Emergency CALLS. Sim slot looks defective. Tried everything. Thickened the SIM, Flashed stock and rooted roms with Odin and Mobile Odin. Several factory resets and wipes. Sim is ok, using it in another phone now. Other sim also doesn't work.
I sort off solved my own problem while leaving myself with a worse one!
Pushing my panic to one side, I discovered that I had wireless and bluetooth but no phone, text or mobile internet.
I checked online to discover it had been blocked!
Phone was a private sale so back to first owner to get network details and see if he has done anything silly - like report it lost or stolen!
Arghhhhhh!
Probably wanted to use his insurance and claimed it stolen. You're screwed I'd think

I finally decided to upgrade from my Nexus 4 to a Z1, and I moved my Three UK contract SIM into the new Z1, it installed the internet & MMS settings and it was fine. But all of a sudden completely random the speeds will drop, the ping will go into the 800s and I can't really load anything on my device.
I'm really not sure what the issue is, whether it's a problem with the drivers, a problem with the actual antenna or if it's just an issue with the software.
I've just tried a factory reset and I'm still getting the same issues, it will be fine most of the time and then just deteriorate until I just can't load anything. The only thing that seems to fix this is a reboot or turning off mobile data and turning it back on again. Obviously this isn't acceptable when I've just paid this amount of money for the phone.
Does anyone have any ideas? I don't want to flash another ROM in case I do actually send it back because won't it void the warranty? If not, how do I go back to stock if I have flashed another ROM?
When putting the SIM back in my Nexus 4, there's no issues at all as there wasn't when I used it before.
I'm really lost, I love this phone but it seems I may have to send it back... Help appreciated!
Contact Call Center of your Provider an tell them to give you the right settings for internet and mms, the settings installed automatically on Z1 not always work. They will send you an sms with the installation. I had similar problem solved with the sms.
Anyone have a fix for this? On Verizon and after almost 4 weeks I have lost my cellular service and data. I noticed when I went to check up on my phone right now that it was finishing a boot-up screen and then never had any bars at the top. Dug deeper and found no service at all. Wiped dalvik and cache and seemed to be bars for under a second and then gone. I am on sensei kernel and am thinking about doing a factory reset and reverting to stock kernel. But I really don't want to lose the benefits it came with.

Well, this is odd. After a month of perfect service, I suddenly cannot get LTE, only 3G. Even nandroids of prior ROM's will not boot into LTE. Is VZW LTE down or should I do a total clean reformat? i do have factory images and everything is backed up. Just a pain.
Very strange. I was flashing various ROM's (CM 12 based - am testing for someone) and at one point pulled out SIM and replaced it. I checked to make sure it is seated right since then. Again, no longer get LTE.
Was on Sensei kernel as well. Let me try flashing stock kernel from ROM first. EDIT: NOPE! Flashing the stock kernel from the ROM did not do it. Looks like total reformat/flash is next!

I just got my Nexus 6 and I am also on Verizon and had the cell coverage drop too. I backed up my apps with titanium backup and did a factory reset and signal came back. I only had it for a day and went to Canada and on my way back to the US I noticed the cell bars were gone. I was just rooted and boot loader unlocked and otherwise stock. I read online that others had this issue when they got to places in the US that had little or no signal. I also noticed that under cellular network settings it loads up with Global under the preferred network type even though it has an option for "LTE (recommended)" and if you choose LTE, global is never an option again until you do a factory reset and it loads with it pre selected. With global selected it works perfectly with calls and LTE, so not sure what that means or if my selecting LTE made it drop the signal after going back from Canada.
Yep, total flash of factory image fixed it. Sigh. Early enough in the day for me to get everything set up again.
Same. About to do it too... I've done too many factory resets with this already. Kind of annoying.
I am in the same boat. Had no problems until I flashed bliss 1.5 then was stuck on 3g. Tried a clean flash of Slim and still stuck on 3g. I will try a stock rom but I am not very hopeful at this point. It's looking a like a reformat here as well :/
Ended up having to format everything and start from scratch again. I'm running a stock ROM now and in weary to try another cm ROM
Don't know if it'll help, but try LTE Discovery app in the Play Store. I use it from time to time to reset my data connection.
Having the same issue, running CM12 daily, have been for a week or so. Midday today it drops LTE, 3g data was working, then a few minutes later to no data. I didn't change anything, nothing new installed. I did reboot the phone at some point before this but that is all...
My only fix was to backup via trwp, restore stock rom, factory reset, reboot & let sim activate, then restore cm12 via twrp... it's a 20-30 min fix all said and done.... pita
Maybe its something Verizon is doing, because I didn't change anything and then next thing you know no data. I hope it's a simple fix for CM12 but I see this popping up more the last few days. Hopefully someone will figure it out. I like CM and prefer it over stock but I am not going to do this multiple times a day just to keep CM...

I just checked and global is still an option for me. I've bounced back and forth, looking to see if anything changes..
Same thing has happened to me last night, lost connection to VZW cell and data. Looking at the field test menus, it seems like the SIM/device understand GSM but NOT CDMA anymore. So I believe the issue has something to do with that. Tried everything, but will nuke and repave most likely....also lost Global as well. and LTE Discovery shows GSM stuff nothing for CDMA
Tried the SIM in another device and it works so its not the SIM.
OK I tried a world of things to recover like some of you may have....its something in Userdata because if I flash everything but userdata it wont work. I am going to try and recover from the backup I had before this happened to see if that works....otherwise rebuild from scratch
will post back
UPDATE: So restoring a backup seems to be ok once you get the SIM back.
Having the same issue over here as well... After a month or AI of having the 6, now I randomly drop service where I would normally have full LTE. I almost NEVER get LTE now and am at most on H with a couple bars then it drops out again. Have also.noticed WiFi connection is very shakey.
Any one find a fix?
I had an issue where i couldnt get my phone to connect any network. Took me long rime to realise, that entering my PIN-number too fast caused the issue xD it unlocked the sim, but didnt let me connect any network... Dunno if this helps anyone, but definetly the most cryptic issue I've ever had.

Troubleshooting my wife's N6 here. Your PIN issue doesn't make sense to me because the phone should be connected to the carrier when locked. Are you talking about WiFi? Because that should be connected too when locked unless settings have been changed from their default (ie, turn off wifi when locked/asleep or something)

I'm talking when you turn on your phone and it asks for pin number to unlock your sim. Some how it seems that if you enter your pin too fast, it bugs the phones radio somehow and you can't connect to your carrier but if you wait like 5sec before entering the pin, it connects to the carrier and the (!) Mark goes away. Try rebooting the phone and see if it helps? Even I think its a weird issue
Edit: OK, just pinpointed MY issue. I have to wait for the "no service" text to change into "emergency calls only" before entering my pin or I don't have any service just the exclamation mark :/

Thanks. I told her about it and she will give it a try, or just remove the pin altogether as a test. It is a weird issue. She is missing important calls from her elderly parents at night and it is rather frustrating. Turning wifi off also seems like a bad fix.
I recently got a new phone from AT&T. I haven't contacted them as I haven't felt it necessary yet. After recently switching from an iPhone 4, I love Android. I quickly rooted it with the Ping Pong method and installed apps such as Busy Box, Greenify, Nova Launcher, Clock Sync Adblock Plus, System Tuner, SD Maid, Titanium Backup, Uninstall, and etcetera. I listed almost all root applications due to it may being a problem with that. My phone worked fine for a while. I noticed it stopped working after some calls stopped coming through as well as texts. Randomly, I see that my texts don't go through, but after a quick restart it seems to work fine. I was wondering if there is any way of getting logs to help someone out there figure this out for me. If unrooting via SuperSU and then factory wiping my device would work please let me know. If there is any information I can provide you I will. The phone worked for the first week fine. Restarts seem to fix the issue until around ~6 hours of time using the device. It mainly sits next to me at my desk.
SMS doesn't go through or receive. Phone calls are not received (Have not tried outgoing). Cellular Data (4G/LTE) does not work.
--Edit:
I have frozen the OTA notifications from wsync. I also remove some bloatware thanks to System app remover (ROOT) by Jumobile. It gives you things that are not CRUCIAL to your system to remove. I removed a few things. Nothing relate to Samsung.
I'd make a backup backup of the phone using your favorite method (I seem to remember that titanium can do this), and try a factory reset to see if that fixes your problem. AoN

Well... Umm. dm-verify verifaction failed... So I'm guessing that I "bricked" my device. Guessing I have to plug it into my pc and do a flash somehow. Any info?
--Edit: Booted into my device with same settings. However I cannot do a factory restore as it always says dm-verify verification failed.
Beyond my knowledge. If the phone still functions, un freeze / restore all the system stuff you disabled, try again? But I'm just guessing. AoN
Use Odin to flash the factory OE2 firmware via PC.
If you're still having issues it may be a faulty SIM card.

Alright, I flashed everything. Re-rooted (I tested before root if the Cellular Data/Messages worked. Cellular data did not, but messages did (and haven't had issues after root). The cellular data still DOES NOT work. I live in a location where LTE is supported. Any info?

This may be s silly question but have you tried toggling the 2 switches under mobile networks/mobile data off then on? One of them is enhanced 4G LTE services. I read somewhere that this might help.

Call AT&T tech support and have them provision your data on the back end again. Just explain that everything works except your data. This can happen if there is a data block on your line or if someone used the my AT&T app to turn off data for lines on the account.
Are you able to make phone calls?
Do you see the 4G LTE logo at the top when wifi is turned off?
