Phone rings but no one can hear me and can't hear them
Hi, I have a wierd one hear.
I have the iPhone 4s on a PAYG sim. Installed the sim and all seemed to be fine. But when I try to make a call there is no sound from the speaker and phone hangs up after a few seconds.
No when I receive a call I can hear the phone ringing but when I answer it I can not hear the caller and the caller can not hear me..
