Just got new s22ultra 4 days ago. Many issues if lagging. But the worst issue is that WiFi calling does not work no matter what I do. Restarted .. checked it on and off many times.. took sim off and back on many times . It just does not get activated . Please help as customer service of Samsung are waste of time. They do NOT respond
Ask your network operator to reset or refresh your network settings. For me also, initially it was not showing, later when I did the same through my network provider then VoLTE and WiFi Calling both activated on S21 Ultra.
