Wi-Fi calling is a feature that is not new, as it was introduced in 2014 with the update of iOS 8, but unfortunately many users are ignorant of this feature, when it was released, not many telecommunications companies support it (and so far it is not supported in some countries), in this article my dear The educated reader who must know everything about the technology, we will get to know this feature in detail, how it works and the country that supports it, in short, you will become a Wi-Fi calling expert.

What is the Wi-Fi calling feature?

You want to make a phone call to someone, and this is the basic feature of the phone from the ground up if you remember, so we call it a phone, not a Facebook browser or an app launcher 😊 and in order to make this call, your phone must have a connection to a communications network that has a cell tower, so when you call the phone This network does its role and works to connect you to the other party, but what if the network is weak and you do not receive a good signal, here comes the idea of ​​connecting via Wi-Fi as it depends on the carrier and depends on a technology called SIP / IMS. This technology allows your iPhone to make and receive phone calls using a regular Wi-Fi network. Instead of routing your voice packets through the nearest cellular tower to your carrier, these packets are passed over the Internet to a console your cell company uses. The end result is that you are talking, but not using a cell tower to do so. For people who live in areas with poor or inconsistent cellular reception, Wi-Fi calling is the absolute lifesaver.

So, in short, instead of calling the telecommunications company via a cell tower you call it via the Internet, but the result is one in the end, talking to the person you are calling, and remembering the receiving person is not necessary to be connected to the Internet, but through the telecommunications company naturally the difference is that you do not use the towers of the telecommunications company that may Be weak in your area, but use the Internet to communicate with it.

We are old and there is no advanced voicemail or call support from the Apple Watch.
