Hi, I'm having phone reception issues. I have the iPhone XR. Even when I used Wifi calling to receive a phone interview call today, it only rang once and said I have a missed call. My interviewer had to call again. She said I didn't sound clear but I heard her fine. I also tried receiving calls outside of my building in the inner Richmond district to see if it helps, but encountered the same issue. I heard my caller fine but the caller said I sounded muffle.
