My tmobile S4 can no longer make or recieive calls
I had an aosp rom insatlled and all was working fine.
Then out of the blue with no warning...I can no longer receive nor make calls. When I attempt a call i hear no dial tone...and when the person picks up the timer starts running but I cant hear anything and they cant hear me..
I flashed other roms and same issue. I even did an odin flash to stock and the problem persist. Both speakers are working. I tested both.
I dont know what the problem can be. Any ideas anyone?? please help
thanks in advance
(PS: all other phone features work, sms, web, lte etc)
