So I had exactly the same issue earlier but mine is working now, but now my husbands isn't, so basically if I call my husbands phone he can't hear me down the other end at all and it was working fine about 3 hours ago then all of a sudden not same as mine this morning??? Any advice or help much appreciated? Also we swapped out sims to make sure it wasn't devices but same thing happened on another device with mine earlier!!!! Sooo odd!
