Cannot call unless on WiFi
when i make phone calls, it works fine if I’m connected to WiFi, and my control center specifically says “ t mobile WiFi “. If I leave home, or get disconnected from WiFi my phone messes up. Basically, when I make phone calls without WiFi, I have no audio, and the person on the other line has no audio. If my control center says “t mobile lte “or “t mobile 4G” it won’t work. I’ve factory reset several times, reset network setting, tried using cellular data, and messed with the settings. Any answers?
