This is a Galaxy S5 on the Sprint Network with Lineage OS version from a few weeks ago.
Last week this was working fine and then since Sunday cell service stopped working completely. The only change I did was updating TWRP, I did not update LineageOS, but I can't imagine TWRP would have affected it. I ended up reverting back to the stock ROM thinking I would have to call Srpint customer service, but then it started working under the stock ROM. Reflashed TWRP and Lineage OS and no service. Tried older and newest versions of TWRP and Lineage OS but nothing works except stock ROM (yuck).
The cellular connection says "no service" with completely empty bars. About every 5 seconds it will flash like it is connected, with most bars and the little R for roaming, then immediately goes back to "no service". I've tried changing preferred networks and looked at settings but can't find anything to fix it.
Any ideas? It's almost like the network is rejecting it but I don't see why it would matter if it is a custom ROM.
EDIT: oh yeah and on start up it says "Activating cellular service... This may take up to 5 minutes" or and then after a while says "Couldn't Activate" and that it may be fixed by restarting the phone (which of course doesn't fix it). Also I'm not entirely sure if it is related to roaming or not.
EDIT2: I'm wondering/betting this has something to do with the ICCID number. I noticed with Lineage OS installed it says "DUMMY_NV_ICC_SERIAL" but with the stock ROM it is a long string of digits. Now maybe I can change the ICCID on Lineage OS? Or maybe Lineage OS isn't reading my sim card properly (from googling what ICCID is)?
I'm having similar issues trying to use this phone on FreedomPop. It looks like the cell services sometimes continually crashes/restarts - a reboot usually clears that up. I also get no LTE data (3G works fine). I have the correct APN AFAIK (https://support.freedompop.com/app/answers/detail/a_id/3322/~/apn-settings---lte-sim). Possibly related to the "DUMMY_NV_ICC_SERIAL" issue?
I've been experiencing this issue for a few weeks now. My LTE data is functional but I cannot send SMS while using 4G. The activation screen pops up when I restart my phone, and it will only activate under Sprint 3G service. I also have the same issue with the flashing service bars, every couple of seconds -- the only way I've found to remedy the lack of service is to turn roaming on and off -- after so many tries, the prompt to select my sim card pops up and it finally connects to the sprint network.
I dont know why this has worked for me but its been a struggle and a wicked pita for me. I use Tello as a provider which is a sprint mvno. This last time to get cell signal i had to flash a stock rom via odin doing a full factory wipe to the phone. I booted into the stock rom to make sure i had lte connectivity. Then booted to download, flashed twrp via odin. Booted into twrp. installed remastered remix 5.7? The next to latest ( marshmello version not neuget ) then booted into RR. Once there i switched it from global to LTE and added the tello apn. I can not connect but i have no idea why this worked. I would love it if someone could tell me why this worked and what i can do in the future to save myself some headaches, flashing factory rom every time i want to change a rom sucks.

Hey guys, quick background. I bricked my SGS3 and had to have it replaced. I think I got a refurb phone because from day one I keep having the same issue. First day I got the replacement phone I rooted it and flashed CleanROM 5.0. Everything was peachy until I noticed that I have no 4G or 3G service. In fact, I had no data connectivity at all. My phone can make calls, receive texts no problem, won't connect to internet. If I restart the phone, I have 4G right away. After a few minutes, the 4G icon is on, but the phone won't has no data connection (when I say data connection I mean it will not go online, no internet, no android market, still have voice and txts). If I attempt to go on internet, I get a message saying "No Signal Found For Mobile Networks". I have installed Network Signal Info and right after a restart it says 4G LTE, data connected, upload+download activity. After a few minutes, it says 4G LTE, data connected, after a little while, it will switch to EHRPD, with data "connecting". Also, in the System tab, it will tell me my IEMI and version of JB running, next to "Radio", it says "unknow". WiFi works perfectly btw. My IEMI is perfectly fine,
I had it backed up. My phone number is still there.
Here is what I had tried so far: Switching into and out of Airplane mode, different programs that reset mobile connection, flashed different custom ROMs, flashed the stock kernel, flashed 3 or 4 verizon Modems, Data wipe, cache, Dalvik wipe, Odin'ed back to stock 4.0.1 ICS and had upgraded it to 4.1.1 via verizon software update, changed the SIM card, and reprovisioned the phone with that *3767*whatever the hell code. I'm out ideas.
If anyone has any other idea that I can try before I take it back to Verizon, please, let me know.

Did you go into your mobile data settings to make sure you're on CDMA/LTE? If not I would select and reboot the phone and see if the problem persists. I don't know if you have tried this but it's worth a shot.
I'm having literally the same exact problem with my mom's S3 except for it's not rooted, complete with 'download + upload activity' and 'unknown' radio. I've yet to find anything in my search, but if I do I'll post it here.

I did try that. Nothing seems to be working.
Okay, so I've been searching the net for days and to no avail. I installed the new Cyanogenmod on my Nexus 5 and found it, well, awful. It kept hanging, restarting etc. Now when I tried to revert back to stock, I downloaded the image file from developers/google/com/android/nexus/images, and there's no 4g. No mobile data whatsoever. I can call, the Wi-Fi is working, but no mobile data. I've tried factory resetting, installing a different radio zip etc. When I install Cyanogenmod again, the 4g works again, but after going back to stock nothing again. Any help?
Wow, this is stupid, but after trying everything, including running every new stock rom, I tried installing the 4.4 (KRT16M) AND IT FINALLY WORKED. I'm gonna leave this up for anyone in the same situation as me.
Well, would you guess, the problem's back, but from a different angle. After installing 4.4.0, and letting the device upgrade itself to 4.4.4, the data worked perfectly. Now I tried to install the android L developer preview and again no data connection.
Does anyone have any idea if it could be a regional issue or something? I tried flashing older radio zip files but to no avail, now back to 4.4.0 .
Try setting a new APN with your carrier settings.
I lost connection all together last Saturday. I flashed CM 11,Friday and all was well. Received a call Saturday, it rang once then lost connection. Had to reboot four times to regain service and that was short lived. After any call incoming or outgoing, I lose service. All APNs are present. WiFi works. SIM alert when SIM is removed. SIM works fine in my N4. Did a complete tear down and it's not hardware related.

Sim works fine in my N4 also
If you loose signal might be a radio problem, still if you have signal but no connectivity try with the new APN, android (CM, stock unless carrier stock) had errors in the APN list for my carrier and I had to manually add it each time I used a new rom for several years.

i think speedtest, advanced download manager, the first time it happend, i had just flashed slimkat 5.10, i set everything up, and i used the LTE quick tile to turn off LTE, my hole signal dissopeared and my phone crashed, i had to restore to stock to get it back. now it does as i discribed erlier.
man, i just got off the phone with a robot from tmobile customer service. she had me turn the phone off and pull the sim card, she told me she "refreshed" my service on her end and the problem was "gone". ya, its not.
Okay so last night I installed CM 10.2.1 on my Samsung galaxy S3 (Verizon SCH-1535)
Everything's running smoothly but for some reason I don't have any service anymore
I'm using a Family Mobile SIM card and APN, still have my IMEI and MEID but in the phone status screen PRL version, MIN and my phone number show up as unknown. Also it says that my mobile network state is disconnected.
Right now I can't send texts and call anyone. However I still do get automated billing texts...
Not sure what to do right now. I still have a CWM backup of the stock ROM. I'm rather new to this custom ROM and bootloader thing so I'm worried that I'll accidentally brick my phone.
Nevermind, i fixed it!
What did you do to fix this? I've had almost the exact same experience over the past couple of days but haven't managed to recover my service.
Background: Flashed back to Alliance 23 (TW 4.3) to see if TW would solve anything and it didn't. I've flashed the ML1 modem and NE1 and still nothing. I even went to a Verizon store to replace my SIM in case the PRL got botched somehow. I can receive texts and send texts sometimes but not consistently, cannot make or receive phone calls.
On Alliance I have the CDMA/LTE/EVDO network mode selected (defaults to global). I was previously trying out CM12.1 and had issues with the modem type sticking to LTE/CDMA (auto prl), after reboots it would switch back to LTE/GSM and the network modes presented were LTE, 3G, and 2G which didn't seem right.
The last time I had a fully functioning radio was with SlimKat Stable. Was having issues sending/receiving MMS and figured it was time to upgrade so went to CM12.1. Since I've tried flashing Alliance and other versions of CM I don't think flashing back to SlimKat will do much but I guess that's next on my list..
I feel like I'm missing something simple. Anyone have ideas?

I may have managed to fix this. Remembering the IMEI issues that happened early on in this phone's life I figured it might have something to do with that.
My IMEI was correct in my phone status, however my phone number and MIN were not correct (phone was 000-000-0023 or something strange) and my MIN was 00. Something definitely broken there.
Steps:
It requires you to have an IMEI backup already. I had done the reboot nvbackup from adb ages ago and decided to give it a shot with a reboot nvrestore.
Phone rebooted but was stuck on the Samsung logo...uh oh.
Had to do a battery pull and reboot to recovery manually.
Restored Alliance 4.3 backup and voila! Full service, phone number and MIN were correct.
Restored my CM12.1 backup image I had been trying out. Right off the bat there was still the same issue of no service.
Dialed the phone info menu (*#*#4636#*#*) and changed preferred network type to CDMA only, ping test succeeded.
Went to Settings | Mobile Networks and things looked more normal which was a great sign. My Preferred network type was actually blank, so I selected LTE (recommended).
Tried a test call to #832 and success!
Rebooted to make sure everything sticks and it does.
That was not a fun experience...still not entirely sure what actually broke but I've got a usable phone again and to top it off it's on CM12.1 which is just awesome so far
As stated I'm using the LG G5 H830 T-Mobile variant. I am getting 4G LTE data connection and everything runs well (Not in any WiFi range) Yet for SMS and calling as well as mobile hotspot I get "No USIM card' error. This happened after wiping the system and formatting data. Rebooted recovery (as per instructions on forum) then installed the stock firmware & Patch with systemless root and xposed. After this I did factor reset when just pulling the sim didn't help. Still nothing. I reflashed just the stock firmware with TWRP and SuperSU and issue is still happening. I've disabled rebooted and enabled the phone radio. SIM is in good condition and tray as well everything is SECURE and should be good to go.
I'm assuming a new SIM might be a solution. But I'm not counting on it and with Labor Day tomorrow for me I wouldn't be able to pick one up for 2 days. So here I am...hoping someone might have a fix. I know I don't have many posts on here. But I am an experienced user....just not with the more basic of problems I guess
Thanks!!
Has anyone else experienced this yet? I'm just curious...I had it fixed for a couple days. I've formatted data and done complete system wipe. Tried it resetting phone with the COMPLETE zip and TOT using LGUP. I'm receiving texts. Not calls. Not able to send either. I've activated new sim, didn't help. LG support just told me to look into warranty. T-Mobile needless to say just wanted. Sim card does show stock tmobile short code contacts but phone number shows as unknown. Hotspot won't work. I've tried setting the phone number to the sim. Nothing.
Anyways. I don't think I messed with anything, even so I've done everything to start the phone from scratch. Going to replace it, just more or less curious at this point and maybe others have had the same issue.
I believe I had the same issue as you and it was driving me crazy. I was constantly wiping data, system, etc but my phone kept giving the message "roaming indicator off" where it should show the name of the carrier. This resulted in me having LTE data and that's it- no 3g, no phone calls, etc. I couldn't even access the mobile network menu.
What ended up causing the issue was the network mode setting under wireless networks. Keep in mind at this point I'm running a patched rom which now gives more options in the network mode menu than the phone came factory with. I have an area at work where I have to switch to 3g, GSM/wcdma preferred network setting, because although I have full LTE signal, my connection goes dead. When switching back from 3g I chose the setting lte/CDMA thinking this would force my phone to stay in lte mode due to another area on an upper floor where the phone will constantly drop lte.
Anyways this resulted in my phone saying roaming indicator unavailable, the inability to make or receive phone calls, and either the mobile networks or network mode menus being grayed out. When stuck in this mode there is no way to put the phone back into the standard "GSM/wcdma/lte" mode. Even a complete reflash won't fix it. I even used lgup, which worked for maybe a day until it force closed the phone app and went back to roaming indicator unavail. I wiped every partition and even reflashed radio firmware. Nothing worked.
What ended up fixing it was using an app called v10 hidden settings which allowed me to access the network mode menu directly and re-choose the lte/wcdma/GSM setting. Incidentally on first access to this menu through the app there are only two network settings available. Once you choose a GSM setting, the rest appear.
I'm not sure if this was your issue but I hoped this helped because this took me about a week to workout.
I was curious if anyone else experienced or has familiarity with this issue. I've been dealing with this since I got the phone almost a year ago. Sometimes when my phone has been idling and I return to check something, the data connection will be unusable. The 3G icon will be visible but internet unavailable (4G works fine, but I prefer to have my phone set to 3G only). It's possible to wait 30-60 seconds for the connection to reset itself, or under settings, switching "Cellular data" or Airplane mode also restores it. Aside from that, the connection is mostly reliable & I don't have any usability issues once data has restored.
I've always ran CM & LOS on this phone so I haven't tried using a stock ROM (solution suggested in an older thread... Mobile data cutting out). I've also flashed the latest Lollipop Radio Firmware (fsg & modem). Thanks for any help.
Edit: I think this may have had something to do with visual voicemail being enabled. I've since switched to AT&T where VVM hasn't worked at all (they suggest using their app) and the problem has gone away.
