Network issues at few places can spoil the day. There are many instances where users wish to make a phone call in an emergency but fail to connect due to the unavailability of the cellular network.

The feature comes in handy if you want calling services without relying on the cellular network. If you are still wondering what exactly this feature is, follow the article to the end for a detailed guide regarding Wi-Fi calling.

Wi-Fi Calling Detailed
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 form and receive phone calls employing a regular Wi-Fi network. Instead of routing your voice packets through your carrier’s closest cell tower, those packets get tunnelled through the web to a controller employed by your cell company, which then bounces them across the network to whomever you’re speaking to.
