WiFi calling stopped working on iPhone 7 after iOS upgrade to 12.3.1
My wife’s iPhone 8 with iOS 12.3.1 would not make a WiFi call, but my iPhone 7 with iOS 12.2 would. After my 7 upgraded to iOS 12.3.1, WiFi calling stopped working on it. When dialing in airplane mode and WiFi on, I get the message “No Network Connection - Connect to a WiFi network or disable airplane mode to place a call” even though this worked before the upgrade. I have restarted the phone, reset network connections, turned airplane mode on and off, etc.
Before, the word WiFi showed to the left of the triangular WiFi symbol in the upper left corner of the phone.
Internet WiFi is working fine. The iPhone 8 is doing the exact same thing.
