I’ve checked this thread and tried all the suggestions but wifi calling is still not working for me.
I have another id mobile iphone and that is working fine. I switch on airplane mode and switch on wifi to force the phone to use wifi calling and it works just fine.
However, on the first if mobile iphone I cannot get wifi calling to work. This is a relatively new id mobile account / sim and I don’t think it has ever worked. One difference I can think of is that it is using a esim so I don’t know if that has something to do with the problem.
It seems that the phone *thinks* is has wifi calling set up. You dial a number and it calls as normal but does not ring. After about 20s saying calling it says ‘call failed’.
