Thank you for taking the time to help. THis link tells me how to activate my wifi calling. It is active. I have dialed telephone numbers while this is active, but I still receive a charge. Am I supposed to use another app to dial phone numbers while wifi calling is enabled, in order that I dont get charged?
I have activated WiFi calling on my iPhone 7, but I am still being charged by Swisscom for those calls. WiFi Calling shows in the window (top left next to the WiFi symbol). What am I doing wrong?
