    Highlights of the Story

    • WiFi calling lets you make calls over strong WiFi network
    • Supports both Android and iOS devices
    • Wi-Fi Calling is free of cost

    There is a new terminology in the telecommunications sector apart from calling which is Wi-Fi calling. Now, this term is very new so we understand that a majority of people might not have come across it. However, it is definitely worth noting what Wi-Fi calling means since it is the future of calling and a great feature too.

    So if this is the first time you have heard of WiFi calling, it is basically a way to call over a strong network while still calling from the same mobile number. Think of a scenario where you have a great WiFi network but poor cell reception, this is where it is most useful.

    With the help of it, the need to make calls through your service provider only will be removed and you will be able to call over WiFi. This means that in places such as indoors where you have strong WiFi but your cell signals are low for some reason, you can still make calls. Also, this will open up a whole new use case such as basement offices where people often complain about not receiving calls or messages where they do have WiFi since it is wired but not network signals since it is wireless.

    Now, it is worth noting that both the Apple and Android devices support it which means you have no limitation in this technology. Apart from the convenience, it should be noted that making calls over a strong Wi-Fi network will also improve its quality meaning that call drops and such incidents will be a thing of the past.

    How does WiFi calling work and what are its charges?

    WiFi calling can also be understood by the fact that calls through WiFi are made over VoIP protocol which stands for Voice over the Internet rather than VoLTE which is Voice over LTE network. To understand this better, apps such as WhatsApp, Skype and Facebook Messenger also make calls through the VoIP network which is basically this WiFi calling as VoLTE calls require a cellular network that might not be available in some remote areas.

    Talking about its advantages, it is also worth noting that you have to pay no additional charges for this service. It works exactly like your normal calls made over a cellular network and the tariff that applies to those calls will be applied to these WiFi calls too.

    Another advantage of it is that on VoLTE, cellular providers used to make calls via your LTE network using data from your monthly allowance. With WiFi calling, that data will be used from your WiFi which means you don’t have to worry about LTE data being spent.

    How to use WiFi calling on your phone?

    As we have mentioned above, it is supported on both iOS and Android devices and you just have to enable the option to call via WiFi. Once it is enabled, you can make calls via WiFi when the signals are not available and it will happen automatically. 

    To enable it on an iOS device, you will have to follow the steps mentioned below:

    Credits: xfinity
    1. Go to Settings on your iPhone and click on the Mobile Data section.
    2. Here, you will see a WiFi calling option if your network supports the same.
    3. In the option is there, enable the “Wi-Fi Calling on This iPhone” and WiFi calling will be enabled.

    To enable it on your Android device, follow the steps given below:

    Credits: xfinity
    1. Go to Settings on your Android device, tap on Network & Internet and then click on Wi-Fi Preferences > Advanced. (Or there might be a direct option for Advanced Calling, it totally depends on the Android Skin your device is using) 
    2. Here, you will see the Wi-Fi calling option which needs to be enabled.
