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.

Hello all,
Lately (meaning, the last couple of days -- perhaps 3 or 4), my phone has been unable to get a Verizon data network connection for a certain amount of time (4G or 3G). WiFi works fine. However, anything else doesn't work, say, for a few minutes, or a hour or so. Sometimes, a reboot will fix the problem, but sometimes it won't.
The odd thing is, the "4G-LTE" icon is displayed and shows activity (up and down arrows blinking), yet I can't browse the web, update the weather, update Facebook, check email, etc., etc.
Does anyone have any ideas? Running BAMF 1.3.2. I am in the middle of NYC (plenty of 4G service). Yes, Mobile Network is enabled in the Settings. Tried a battery pull as described above AND a SIM card pull. Still no fix.
I had a similar problem a few days after I got my Thunderbolt. I was still on stock yet. I ended up going to the Verizon store and they did a hard reset to fix it. It sucked because I lost all my data but since it was new I didn't have much on it. If you back up everything with Titanium Backup it shouldn't be too bad tho, factory reset is under "SD card and storage" in the settings menu.

There have been many problems with the TB and data/network problems as of late. I believe it to be because of this new 4G rollout that is coming Thursday, plus the fact we will be seeing an OTA quite soon they are propbably preparing the network for that, thus giving all of us all these weird problems that we have been having.
(everything above is just rumor and based on my 100% factual opinions )

You are describing the same problem I'm having and I also live in NYC. But, I have no problems getting data when I force the phone into 3G mode only.
I notice the data connection problem even though the 4G symbol is up when I don't have cell reception for a while...like being underground while on the subway.
Turning the phone off and on or rebooting seems to fix the issue. I'm thinking the phone has handoff issues with whatever tower is near by.
Anywho, I did the "data fix" by changing the EVDO setting from eHRPD to Rev. A. I dunno if that'll do anything.
I'm on the stock 4.0.4 update from AT&T. I have the 4GB Data tethering plan. Data connection stability in general (in the NYC area) seems to be kinda crappy. My old Windows Mobile phone holds an active data session much better. I mean I can be getting email fine, then I'll notice it hasn't downloaded mail for like an hour...and sure enough, the signal indicator isn't blue any more. Need to toggle airplane mode, and then it's fine again, usually. Sometimes I have to reboot. Sometimes it totally loses signal.
I notice the problem is worst right after I finish a USB tethering session. Anyone else notice this, and have a suggestion on how to make this work better? I've tried going back to the radio that I was using with a custom ROM (NexusBeam), but it didn't make any significant change.
The irony of why I moved back to stock was to get Google Wallet. Which isn't in the ROM. Grr.
Any ideas?
Thanks!

Sorry if this has been mentioned before. I did extensive searching without finding anything before posting.
I have been having some very strange data connection issues with my Verizon S3 running BoneStock v3.3 (awesome rom BTW, much thanks to andybones and all contributers) over the past few days. Starting a few days back, my signal strength and transfer rates while at work were much lower than normal. While investigating this, I found myself exploring the settings menus (About Phone > Status and More settings > Mobile Networks) to investigate the signal strength more often than normal (and I believe it had been the first time I had ever been to the "Mobile Networks" view).
This morning, I noticed that I had a 3g connection only at my house (this is unusual as I normally have a very strong 4g connection at home and a pretty decent one at work). Toggling in and out of airplane mode, or rebooting the phone would result in a 4g connection for about 1-2 minutes or so before it would again drop back to 3g. Using the Speedtest app, I would get about 0.5Mbps or so down, and the upstream test would not even finish before showing "Network Communication Issues" and dropping back to 3g. Additionally, my phone has been running really hot and the battery has been draining much faster than usual. Meanwhile, I had ruled out a regional network issue by testing my wife's iPhone 5, which was maintaining a solid 4g connection while mine was dropping.
While Googling for this issue, I ran across lots of articles/discussions referencing the bad OTA update Verizon sent out back in June. It struck me how perfectly the typical list of symptoms for that update matched what I was seeing. However I couldn't see why my phone would be having such similar issues, as I never received that OTA update before flashing BoneStock, and have had weeks on BoneStock with no problems at all.
Just for kicks, I switched the "More settings > Mobile Networks > Network Mode" to "Global", then switched it back to "CDMA/LTE/EVDO", then rebooted the device, and this has apparently fixed my issue!
To be absolutely clear... the current setting for "Network Mode" was already set to "CDMA/LTE/EVDO" when I checked the setting. I merely switched it, then switched it back. That was 2 hours ago, and my connection has been solid as a rock since then and the phone temperature and battery life has gone back to normal.
Doing more research, I saw that apparently the bad Verizon OTA update configured "Network Mode" to "Global" by default, and that many had fixed their connection issues by switching this to "CDMA/LTE/EVDO". Sounds very similar to my problem, except my UI was not showing that it was currently set to Global.
So, hooray that it's working, but I'm not sure what I did or how it was broken in the first place. My working theory is that the phone's Network Mode was actually set to Global somehow through some other mechanism but the UI was not displaying the setting properly, and by switching it and switching it back I overwrote that setting.
Does this ring a bell for anyone? I'd love to figure out what exactly happened, and hopefully prevent someone else from going through the hair pulling that I went through. Thanks in advance!
Hi,
my phone lately shows an high battery drain, random reboots and signal losses.
Aside from supersu and adaway everything is stock. last-kmsg shows "modem_err"
A few days ago I updated my phone from MMB29V to MOB30H, right after this I went on holiday. (left country)
While being there everything worked fine.
But right after I comeback home the phone started to act strange (see title).
Anyone an idea what could cause the behaviour?
Maybe the update? And I didn't noticed it in holiday because of my disabled data connection?
I tried:
a full wipe, reflash of stock image
flash of old radio
looked out for wake locks (there are non)
using phone without apps (only stock)
Might flashing old bootloader/kernel help?
Maybe interesting:
My provider (Klarmobil (T-Mobile DE third-party)) tends to switch my network mode between 3G and HSPA,
from what I heard and see this depends on my data usage. (HSPA while surfing, 3G while idling). I have the "feeling"
it disconnects when it tries to switch.
Thanks for your help!
Edit:
Added another set of logfiles, showing a "signal-loss", it got so far to ask for my pin again.
Sadly errors still keep happening. I tried the march build and also a custom kernel, no change :crying:
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.
