phone calls can't hear me but I hear them
My iPhone 6 Plus works great! Nothing wrong until recently, no one can hear me on the other end of a phone call! I hear them perfectly fine. FaceTime video and audio work. It seems if the person I'm trying to call doesn't have an iPhone, I can't talk to them except text. I can record my self with a video and message. I tried switching with another person's SIM card. Still had trouble. When it first started, the person on the other end only heard static. Now they hear nothing, not even background noise. Help! What piece do I need to reconnect or replace!
