Apple has long supported FaceTime Audio for the iPhone, which allows iOS user to chat with other iOS user by means of Wi-Fi and moreover if your mobile carrier allowed user can use it via cellular data. Down here you can find few easy steps to turn-on iPhone Wifi calling.
What is Wifi calling:
Unlike FaceTime, Wi-Fi calling is carrier-driven, and depends on a technology called SIP / IMS (IP Multimedia Subset). The technology enables your iPhone to make and receive phone calls using a regular Wi-Fi network.
Instead of routing your voice packets through your carrier’s closest cell tower, those packets get tunneled through the Internet to a controller used by your cell company, which then bounces them across the network to whomever you’re speaking. The net result is that you’re talking, but you’re not actually using a cell tower to do it. For people who live in areas with poor or inconsistent cellular reception, Wi-Fi calling is an absolute savior.
If your carrier supports Wi-Fi calling, it’s also a wonderful to get sharper and clearer voice calls when chatting with other people.
