So switched back to 5g and guess what phone went to 5g and the problem came back  went back to 4g same number no problem. Sorry but I fail to believe that 5g is not the problem. Having checked oppo say Tesco doesn't yet support wi fi calling ,guess I just have to wait. Checked on system color os 13.0 android 13, so up to date * as does Tesco's think it is just a brand change as it looks the same |
Calls use the old GSM standard I believe which is 2G or VoLTE which is 4G. So poor 5G will have no effect on your ability to make calls. Plans to kill 2G are in place to be done by 2033
