Does Freedom have WiFi Calling? You can check in: Dialer - Three Dot Menu Top Right - Scroll down and see if WiFi Calling option is there.. If it is - Open (Pull Down QS Tiles - Click on the Three Dot Menu Top Right - Button Order & Then add WiFi Calling QS Tile 🐧
I'm with Bell and although I do have access to Wifi Calling with my S8+, there's no such tile available to add on my side either. it's a carrier's decision on if he allows it or not to be displayed I believe. this might explain why he cant find it as well.
