Wi-Fi calling works much like a normal phone call in terms of user experience, you dial a contact number as you usually would. Just like a normal phone conversation, you can utilize all of the usual features in wi-fi callings, such as three-way calling and speakerphone.

You should take advantage of this quick development in the phone system by using Wi-Fi calling. Even though you’re not near a mobile network, you can perform Wi-Fi calls using your home broadband or Wi-Fi hotspot.

What Are The Benefits Of WiFi Calling? 🤩

The common benefits of Wi-Fi Calling are as follows:

1. Cellular network is not available everywhere

If you’re too far away from cellular towers for the signal to reach you, or if the signal isn’t powerful enough to penetrate your house, then this could happen.

2. Save Cost on Phone Calls

One of the reasons to choose wifi callings over cellular network phone calling is that wifi calling simply saves your money on phone calls.

If you use the free VoIP application then you just need an internet connection to make a call, it will be free of cost.

3. WiFi Availability

Using a wifi connection, you can make wifi calls from anywhere in the world. Nowadays, wifi connection is even available in public places like hotels, restaurants, marts, malls, public transport, parks, etc.

Benefits of WiFi calling

But those public wifi connections might not be as reliable as your personal & office wifi. However, you can make and receive wifi calls from those public places with wifi connections as well.

These are some of the reasons for using wifi calling but we will discuss its benefits in brief in this article.

Stick to the end!

After knowing what is wifi calling & some reason to use it, you might eagerly want to know how it works.

Let’s discuss! 🤝

How does Wifi Calling work?

If you dial after turning on Wi-Fi calling, your phone will automatically find the powerful network available. The call will then be routed over a Wi-Fi or cellular network, depending on which is the strongest at the moment.

If a Wi-Fi network outperforms your carrier’s cellular network then only your call can be routed through Wifi.

However, a technology called “VoIP (Voice over Internet Protocol)” service is the easiest & best way to make a Wi-Fi call. It establishes a phone service by connecting to a provider over internet service.

It appears to you to be very simple & uncomplicated, but there are a lot of things that happen behind the scenes to make it work.

VoIP technology is used to make calls via apps like KrispCall, Viber, Messenger, WhatsApp, Skype, and many other VoIP Applications. You can easily make calls using those VoIP applications with the help of a internet connection.

You don’t need to do much to obtain a robust network connection with today’s powerful devices. Businesses or individuals can use applications like KrispCall to make and receive Wi-Fi calls using any device with internet access, even if it doesn’t have a cellular network signal or even a SIM Card as well.

Wi-Fi calling, at its most basic level, employs VoIP to give callers a better calling experience.
