Using WiFi Calling, you may use your mobile device to place calls via a WiFi data network. It is supported by all major carriers and does not need any specialised software or carrier plans. Making calls over the new LTE networks is largely the same, and call receivers still see your mobile phone number. Your phone will automatically use the WiFi network you are connected to to make the call if you are in a location with excellent WiFi but poor mobile coverage. Your carrier's minutes plan is still applied to calls made when connected to WiFi.
