I have a 6A on T-Mobile. Exact same issue for me.

Do you use wifi calling when you are at home? It has been my experience that T-Mobile WiFi calling is absolutely terrible, and I've oftentimes wondered if something in the software "locks" into WiFi instead of switching to cellular data, until the phone is rebooted.

Yep! I work from home and use WiFi calling. When I leave my house is usually when I have the issue.

Sometimes it'll work fine for a while after leaving and a few hours later I notice I don't have service.
