I'm on sim only and my phone is dying. Local network reception is very poor (O2 is the best of a bad lot) I really want Wifi calling in the house. what budget android phones have compatible firmware to allow wifi calls
WiFi calling should be compatible with all the latest phones but O2 will only guarantee it with phones they sell themselves.
I have no affiliation whatsoever with O2 or any subsidiary companies. Comments posted are entirely of my own opinion.

It is a GSM standard nowadays and we have iPhones, Motorola, Pixels and Samsung's all working with WiFi Calling, and in the past seen OnePlus as well .. Ones to avoid really are Xiaomi, Honor, Huawei etc
