I recently rooted my Samsung GS4-i337m variant.
I had a SIM that worked pretty well. It used to go out a bit, but a reboot would work fine to get it working again every few days.
After everything was fine, and working stable, I decided to install a ROM.
I installed PA, and verified that it was the correct ROM, for my model.
It worked quite well for a few days. The SIM had the same problem as before, but a reboot would work fine, like before.
Today, I had time to get my SIM changed, and after doing so, after rebooting the phone, it immediately refused to use the SIM card. It did not give a warning, but simply said "No Service." After trying to go through multiple settings to no avail, I decided to restore to an older backup, from my stock ROM.
I tried this, got an error, and had to stay with Paranoid.
I still have the same problem.
So, are there any solutions to this?
Any app or setting to fix this?
The phone is not unlocked.
Phone used to work fine on PA, and after changing SIM, it rejected the SIM. Help.
