Wifi Calling on S25 Ultra

[SteveGriff]

I have recently upgraded to an S25 Ultra from the S23 and have intermittent connection to WiFi calling. I am using dual sim as the phone is a works mobile but don't seen to have the issue with the Vodaphone sim as often. I never had this issue with the S23 Ultra

Sky only guarantee WiFi calling if the device was purchased from them.
