Wi-Fi calling still connected to old carrier
I have a new cell phone carrier but brought over my iPhone from my past carrier. I cannot enable Wi-Fi calling it says to contact pass carrier.
Did that they can’t help me. Did a factory reset, turn the phone off and on, did the network reset, rebooted my router, nothing has helped. How do I get my old carrier Wi-Fi call settings out of my phone?
iPhone 11, iOS 18
