WiFi Calling
Is there a way in settings on iPhone to turn off cellular so that WiFi calling is always used? We live in an area that has 1 bar of service though ATT and because of this I have to go to the basement to make calls to eliminate any cellular signal. Otherwise the iPhone tries over the 1 bar and fails. We used to have a MicroCell device which worked flawlessly but I was told ATT no longer supports these. Thank you
