Samsung A34 5G wifi calling

There is an easy solution to make sure you have wifi calling working when you want it, such as at home. Just put your phone into airplane mode and then turn WiFi back on again. As there is no mobile data connection, WiFi calling is the default, and only connection method. If you have mobile data and WiFi calling on and there is the slightest of mobile data signal, then  the phone will not use WiFi calling. You have to make sure that there is absolutely no mobile signal for WiFi calling to be activate. Don't forget to get out of airplane mode when you go outside though.
