My phone (Samsung S22U) will not make or receive calls. This is new behaviour - it has worked fine for two years. Internet connection (4G/5G) work fine. Also I can send and receive text messages. Only voice is problematic. Dialling out i get the “calling xxx” message then “unable to connect” Calling in, the caller hears eight or so rings then the connection cuts. There is no ringing nor “missed call” notification on my phone. Very occasionally I get a message “Not registered on the network” when dialling out, but not every time. And today my SIM Manager tells me my SIM has an “unknown number”. Ideas, anyone?
