S22 ultra call issues.

[Stevegbee]

My S22 ultra regularly won't accept or make calls. Immediately hanging up calls as I make them. The only way to remedy it is to restart the phone. Happens every couple of days

Sounds like a connection issue, have you got either WiFi calling or Volte switched on?

I mysteriously had this issue today after placing a pre-order for the s25 ultra in my cart. Never an issue b4 today. But I can send and receive text messages.  AT&T says it's an issue with Samsung!
