WiFi & 4G Calling
With WiFi Calling you can make and receive calls in any location that has WiFi network, even if there's no regular phone signal.
4G Calling is just like Wifi calling, but it works using your phone's 4G data rather than a WiFi network. So long as your phone has 4G coverage, you can use 4G Calling to make and receive calls and texts.
