I am now on my 2nd Galaxy S10+. With wifi calling turned on, I cannot make/receive calls nor can I text. I have performed multiple factory resets, took the phone to an authorized Samsung repair center for a full diagnostic...nothing. I even swamped the phone out. I have been on various wifi networks, same issue. It works when i initially turn wifi calling on within the phone settings, then it stops. The moment i turn OFF wifi settings everything works again. I have even turned off mobile data when on wifi, no good either. I cannot imagine I'm the only person experiencing this especially since it's now happening on 2 devices. I never had any issues with my S9+ and wifi calling. Please help!
