Help please!!!! I recently had my digitizer replaced after it was broken from a hard impact. When I went to put my simcard in the phone and fire it up when I noticed that I was not receiving any signal whatsoever. All I got was a Do Not Enter icon in the top right corner. I know my simcard worked because after I flashed about a half dozen different Roms it asked me for a simcard but still showed no network. I took it apart to see if the repair guy had missed a ribbon but everything seemed to be ok. My imei is still intact. Signal strength is -113dBm 0 asu, Mobile Network Type is unknown, Service State is out of service. Mobile Network state is disconnected. Bluetooth and Wifi both work fine. I have tried everything software related that I could find and nothing seems to work. I am on a stock Bell rom that I updated to the MF1. My APN looks like it is right, Network mode is set to auto, but it cant find any networks. Is this a hardware issue? I sure hope not. Please any insight would be fantastic.

I've got a strange problem that I cannot solve or find anyone else that has had the same problem.
I recently updated to Minco V4 and since my status bar has been showing no signal and mobile standby shows 100% without signal yet I have mobile data. I cannot make any phone calls but can browse the internet. No amount of rebooting, airplane mode on/off will work. I've also gone back to both stock ICS and JB where the problem still exists.
My network is T-Mobile and it won't let me manually connect to it but the phone will occasionally register when I select automatic although it doesn't correct the fault. Anyone have any ideas what has gone wrong with my phone?
UPDATE: It seems I can only get a phone signal when select 2g T-mobile network only or connecting to T-Mobile orange. If I untick 2g networks and it connects to t-mobile 3g I can't receive or make calls.
Does your Radio and baseband match?
I installed the linked radio from the MiNCO thread after flashing the rom and discovering this issue yet it made no difference.
I got a phone signal momentarily about 15 mins ago which allowed me to make a short phone call to test it. I then accepted the JB system update from Google and now have no phone signal, just data.
I got a SGH T989 and got it unlocked for use in India..worked great for 2 months and then i rooted,flashed AOKP jellybean using CWM....after that, worked great for 1 month... Now the problem is that.....
My phone shows full signal and in the "about phone" menu,the signal strength is -100dBm BUT i cannot make calls and i'm out of coverage area for others.. The weird thing is that this happens only at certain spots (unfortunately, my workplace)...the device works just fine in other places...i ruled out a network issue coz my sim is good in other phones at the problem zones.
I tried another network's sim and it had call drop issues....the call would get disconnected after a few minutes and the duration of the call wasn't constant....this was also when the phone showed signal strength of around -100dBm. I had used this network before and it was working good with the phone..
I tried a master reset, complete system format in CWM recovery, reverted back to stock rom using odin, changed radios (UVLE1,UVLH1 and UVLI1)....nothing has worked so far.
There was no external injury or water damage to the phone, i didn't install any app outside of the play store and i use genuine charger for my phone.
I love my phone too much to let go....please gimme a solution
Thanks!!

Are you using WiFi calling? or is this just TM network?

I got it unlocked and i am using the phone with Docomo network and also Airtel network in India..
I receiven a m919 with strange network behaviour
I used a profesional tool : Octopus Box Samsung to repair EFS and NVM Area, I unlocked again and phone started to work decently (not as expected) after 1 or 2 days the phone came back as in the initial day.
To explin better:
it always says searching, but it do shows 3 or 4 signal bars, if you find network manually it finds the network but if you try to register it give error registering on network.
I dont know what else to try
when I repaired everything with the tool it started to work well, but indoors it had no network or dropped calls, usssd codes failing, etc.
outdoor it worked fine but as I said only 2 days.
in my counry there is only one network and it's 2G/edge not 3g or 4g here.
is there any trick to make these phones'modem work only at 2G mode and never try to find/connect/switch to 3g/4g/lte. etc? maybe this could make phones work nicely on 2g networks?
I have noticed most 4G/lte phones has poor signal reception here in my country.
I just bought a T Mobile LG G3 (D851) for use on AT&T. The guy I bought it from got the unlock code from T Mobile and that is all squared away and unlocked. Things are basically working on AT&T, but data is not working reliably for me. It works fine for awhile, then it just stops working--the 4G/LTE logo in the status bar disappears and I have no connectivity. I can still make phone calls and send/receive SMS texts (though no MMS texts), and if a wifi network is around, that works too. Rebooting does not seem to correct it (though it does start working again eventually).
I don't know if it is just random, but it does seem to happen after I'm leaving somewhere with wifi (and that may not even be relevant--might be that's just when I notice it).
I have verified my APN settings (as well as tried other slightly different settings I've found around the web), but the data network still drops out. Yesterday, I discovered a technique that seems to reliably bring it back on after it has dropped out. If I change the Network Mode to anything else (ex: just GSM), then back out of the network options menu... then go back in and set Network Mode back to LTE (etc). Every time I have tried this, I get the 4G/LTE logo back in the status bar and my connectivity is back.
I know there is some difference in the LTE bands supported by AT&T and the T Mobile LG G3 (D851), but the phone supports band 17, which I'm told is the main LTE band used by AT&T. At this point, I think I'd be satisfied just to have consistent 4G (non-LTE) data.
Any idea what might be the issue? Or anything I can try out? I'm considering flashing a different rom to see if that helps, but wanted to exhaust other options first.
Thanks...
Hi. Recently, my signal bars on my phone went blank and I can't get my signal back. I tried to remove/reinsert my SIM card and after a few tries, my phone stopped detecting it altogether. I got a new SIM card, but the problem still persists. Searching for service providers gives several results, but all of them are "unavailable at the moment". Factory reset didn't help either. Please help

If it was working fine and you didn't change anything and all of a sudden you just get no signal, I would first call your service provider and have them check it out, and if they say everything's OK, you should get a new sim, and have them switch the number to it, and if that doesn't work, it's probably a hw failure. The only things you could check on the phone is if you accidentally switched data off, or hit airplane mode, etc.

Airplane mode is off, data is on. I already got a new SIM, but the problem persists. Sadly, I'm not sure I can call my service provider, since I'm studying abroad and I'm yet to learn the language. And I'm really hoping it's not the hardware, it shouldn't be. Also, I don't have signal bars
