Wifi calling isn't available on Google phones, seems to be some issues between them and Google.

I had WiFi calling on my P20 Pro, but will not work with same SIM in my Realme 9 Pro plus - have tried to get them to help, without joy & their IMEI checked for VoLTE says my phone is not compatible. They seem to have problems with more than Google phones. Still great value, but if wifi or 4G calling are important, maybe test before you port?
