[Q] Galaxy S3 "no service" after flash - Galaxy S III Q&A, Help & Troubleshooting

Help! After flashing my phone I have full signal bars but there is a warning sign saying "No service". If I try to make a call is also says "not registered on network". Ive tried everything I can think off, restoring my efs folder and flashing back to stock. Nothing has helped.
What could be the problem, is it a radio problem? Modem problem? I have no idea :crying:
Please help me.
A really weird thing is happening however. If someone rings me they get the ringing tone, but my phone does not ring. If they leave a voice mail then a "balance" popup appears on my phone. Weird or what?
Thanks!!

Have you checked EMEI number is still the same?(Dial *#06# on dial pad and check it matches up with EMEI on the box) Or that your EFS folder isn't corrupt/gone? (System/EFS)
Before flashing anything you should backup your EFS as this can become corrupt when flashing ROMs and then you're phone is pretty much a tablet, no 3G will work unless you send it for repair.

Have you performed Task29 before flashing a new ROM. I had a phone freeze problem similar to what you mentioned and Task29 sorted it all out. Try that.

Were you able to perform calls with Stock ROM? If not, it's time to get the proof of purchase from the person you bought it and get back to the shop.
task29 then flash a different rom.

[Q] X10 Cannot receive/send texts or make calls or answer calls.

I can't send or receive SMS. When i try all i get is 'could not send' Also, i cant make calls and when someone tries phoning me they get told me phone is turned off.
Iv tried the simcard in different phones and it works fine in them.
I haven't flashed the phone or anything like that, iv also tried to re-install the firmware but that hasn't fixed the problem.
Any ideas?
bump =) Surely someone on here can help this guy out

Seems like hardware issue. Send for repairs.

Help! Can no longer make and receive calls.

So I was attempting to get VoLTE to work on an M Rom. I flashed 6.11.3 but even though VoLTE was enabled, calls kept dropping to 3G. After a few hours of frustration and flashing different roms on the forum to try to get VOLTE working, I conceded and flashed my original M Rom. However I couldn't get it to connect to my mobile network. I then realized that my IMEI and who knows what else was corrupted / showing 0. I managed to flash the IMEI using a guide on this forum and I can now get it to connect to the network at least for data. However when I try to make a phone call, I don't hear any ringing. And when someone tries to call me, their phone rings and eventually goes to voicemail. However nothing happens on my phone / no call is shown. Any help would be much appreciated.

Help phone calls won't show up

So ive done absolutely nothing to my phone and all of a sudden my phone calls won't show up. My phone will vibrate when ringing but I have to access the call by going to the phone button and pressing return to call in progress. How do I fix this help.
Maybe you lost IMEIs after update.
*#06#* to see if imei is original or 1111111111111 and 2222222222.
The imei number is the original one :/

Call ended as soon as I call and not reachable when someone tries to call (Lineage16)

As the title says, as soon as I start a call it ends and when someone tries to call me, they get the voicemail saying that I'm not reachable and I get an SMS saying that someone has tried to call me while I wasn't reachable, but I don't get any call popup on my screen.
Tried flashing every modem firmware, wiping cache, switching from google phone to stock, turning off volte but none of those worked.
Please help me, I've been struggling with this problem for three days and it is impossible to work like this.

Check your APN settings and if necessary correct them to what your carrier says they should be. I had a similar problem and that was the fix.
If that's not it, try your SIM in a different phone if you can. You might have a bad SIM.
Heyyo, here's an APN list that might work better for you since it is updated by Google.
