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 worth knowing what Wi-Fi calling means. As it is the future of calling and an amazing feature too. So, what exactly is WiFi calling?

So if this is the first time you have heard of WiFi calling, it is a way to talk and text on the smartphone from locations where it is difficult to reach a strong cellular phone signal. Think of a scenario where you have a great WiFi network but poor cell reception. This is where it is most useful.

With Wi-fi calling, you can place and receive calls over a wireless internet connection instead of using a cellular signal. This means that in places such as indoors where you have a strong WiFi network but your cell signals are low for some reason, you can still make calls. This service is compatible with most Android and iOS devices with almost similar user experience to any other phone call.

Apart from the convenience, making calls over a strong Wi-Fi network will also improve its quality. This means that call drops and such incidents will be a thing of the past. This service is easy to set up and can save minutes on cellular subscriptions. Or avoid the requirement for the contract altogether, in presence of an active Wi-Fi network.

How does WiFi calling work and what are its charges?

In Wi-Fi calling calls are made over VoIP protocol. Which stands for Voice over the Internet rather than VoLTE which is Voice over LTE network. It works similarly to other VoIP applications such as WhatsApp, Skype and Facebook Messenger but with slight differences. It works by transmitting cellular data packets as Wi-Fi VoIP via a Wi-Fi connection across the internet. Now from the internet, the data goes to the cellular network and then back to the answering party. However, the smartphone must support the new feature for it to work.

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 compatible with both iOS and Android devices and you just have to enable the option- to call via WiFi. Once the feature is on, you can make calls via WiFi when the signals are not available and it will happen automatically.

How to use WiFi calling on your device in India?

You would be curious to know how you can use WiFi calling in India. Thus, it is worth noting that Airtel and Jio have already enabled WiFi calling country-wide which means that you can take advantage of making calls over WiFi on your Android or iOS device. If you are using any of these networks and have a compatible device, WiFi calling will be active by default and automatically too.

However, there are a limited number of devices that currently support both Airtel and Jio networks. At the moment, Airtel supports Apple iPhones ranging from the iPhone 11 series to the iPhone SE.

On the Android side of things, the network supports the latest OnePlus devices which include the OnePlus 7 series and the OnePlus 6 series. Xiaomi devices such as Poco F1, Redmi K20 series and Redmi Note 7 series support the Wi-Fi calling feature too. Furthermore, the feature is also compatible with most Samsung devices too.
