Hi @Frostbi, let me see if I can help out here.
In order to be able to make calls with Wi-Fi Calling some conditions must be fulfilled:
- you have to use a phone that supports Wi-Fi Calling.
- your service provider and subscription (incl. SIM card) must support Wi-Fi Calling for the device model you're using.
- depending on operator, your phone must sometimes be operator-branded and/or use operator-customised system software.
- your phone must be in range of a Wi-Fi network.
If all these conditions are met, Find and tap the Phone app > Tap the Menu button (three vertical dots) > Settings > Calling accounts > Select a SIM card > Wi-Fi Calling. If WiFi-calling isn't available in this menu, contact your service provider.
I hope that helped!
