I have tried everything, and at my wits end. Samsung tell me its a set up problem with o2. I have spent hours on the phone to o2 who keep resetting the settings and tell me everything is set correctly. Does anyone have any ideas please. Thank you
If you have the My O2 app Scroll down to the bottom. Tap on veiw all Go into device details Here you should have WiFi and 4G calling Here you should have the option to activate WiFi calling if your device is supported on your account
Then go into the phone app on the phone Tap on the 3 dots top right corner Go into settings Scroll down to till you see WiFi calling
