WiFi calling is a new system on smartphones that allows users to make and receive phone calls over a Wi-Fi network instead of using a cellular network. This can be useful in areas with poor cellular coverage or in places where the user does not have a cellular plan. The call quality is generally the same as if the call were made over a cellular network, but it may depend on the quality of the Wi-Fi connection. Some cellular carriers also offer the option of calling over a cellular network as a fallback if the Wi-Fi connection is lost during a call.
WiFi calling works by routing a phone call over the internet using Voice over Internet Protocol (VoIP) technology, instead of the traditional cellular network. This means that as long as the user has a reliable internet connection, they can make and receive calls and texts as if they were on a cellular network.
One of the benefits of WiFi calling is that it can provide better coverage in areas with poor cellular reception, such as in a building with thick walls or in a remote location. It also allows users to make international calls at a lower cost, as the call is treated as a data transfer and not a traditional phone call.
Another benefit of WiFi calling is that it can save on cellular data usage, as the call is not using cellular data. This is especially useful for users who have limited data plans or are traveling abroad and don't want to incur high roaming charges.
However, it should be noted that some carriers may charge extra for WiFi calling, or include it in certain plans only. In addition to that, WiFi calling is dependent on the quality of the internet connection, so if the connection is weak or unstable, the call quality may be affected.
So, WiFi calling allows users to make and receive phone calls using a Wi-Fi connection instead of a cellular network, providing better coverage in areas with poor cellular reception and saving on cellular data usage.
