WiFi Calling is a feature offered by major mobile network operators that allows users to make and receive phone calls over a wireless internet connection rather than a traditional cellular network. When enabled, the phone will use the internet connection available through Wi-Fi to route calls to the network, which can be useful in areas with limited or no cellular coverage.
This feature can also be useful for international calls, as it allows users to avoid expensive roaming charges by using their home country's Wi-Fi network to make calls. To use WiFi Calling, your phone must support this feature, and your mobile network operator must offer it as part of their service.
Every smartphone model that supports WiFi calling has its own steps. But most of these are quite the same.
