My iPhone 6 has terrible call connections when I am connected to a wifi network. I can hear the person on the other side just fine, but no one can hear me. Anyone else experiencing a similar issue?
If this is at home, did you upgrade your router? works best with the new ac wifi band and certain settings. Tmo was offering a free router that has these features, as they love it when users go onto wifi and off their cell towers...
I got the free router but haven't set up. I've had echoing calls (on their end) using wifi call with my current non-ac band router.... my end sounded fine also..
