What is WiFi Calling and How Does it Work?
WiFi Calling is a technology that allows users to make voice calls and send text messages over a WiFi network instead of using a cellular network. It works by using the internet connection to establish a communication link between the caller and the recipient, bypassing the traditional cellular network. This technology is especially useful in areas with poor or no cellular coverage, as it allows users to stay connected and make calls using a WiFi network.
The process of making a WiFi call is similar to making a regular call, but instead of using cellular towers, the call is routed through the WiFi network. The call is then connected to the public switched telephone network (PSTN), which allows the call to be completed to any phone number, whether it’s a landline or a mobile phone. WiFi Calling is supported by many mobile operators and is available on a wide range of devices, including smartphones and tablets.
Do I Need a Mobile Signal for WiFi Calling?
