Placing a Wi-Fi call it’s just like placing a regular cellphone call. Wi-Fi calling allows you to make high-quality phone calls (and send texts and other media) to people who are connected to a Wi-Fi network. When Wi-Fi calling is turned on or enabled on your mobile device, all of the Wi-Fi networks that the device connects to do the work that would otherwise be handled by cell phone towers. Today, most major cell phone carriers now support Wi-Fi calling, and the option to connect to Wi-Fi now comes standard with the most recent iPhones and Android devices.
In the past support for Wi-Fi calling was limited. Generally, your carrier and phone will determine if you are able to place phone calls through Wi-Fi or not.
Wi-Fi calling uses a Wi-Fi connection to make phone calls over the internet, instead of using the network of cell towers owned by wireless carriers and providers.
