As phone users, we’re always looking for better voice quality and network performance. With each iteration of network technology – 3G, 4G – we've expected and received better data speeds and call quality. However, for many of us, performance is still not satisfactory especially for making calls indoors. To address this, last month, telecom provider Airtel has brought WiFi calling, a.k.a VoWiFi, to their users. Even though it is evident that it uses WiFi for calling, how exactly does it work? What are its benefits, if any? How can you use it? Let’s find out.

What Is WiFi Calling?

Calls using data connectivity, instead of GSM, was already common with VoLTE ever since 4G arrived. With WiFi calling, phones can now use the data connectivity provided by robust WiFi networks instead of LTE.

How Is It Better?

WiFi connectivity is much better as compared to mobile data. This is mainly because WiFi is powered by wired broadband connections, which can help you avoid call drops and poor audio almost entirely. For instance, even within apartments with thick walls or high-rises, connectivity will not fail.

How Can You Use It?

Here are the quick steps to check or implement in order to use WiFi Calling:
  • For starters, you need to have a SIM from either Airtel or Jio.
  • Your phone must have support for WiFi calling. Popular smartphones from Apple, Samsung, Xiaomi, OnePlus and more have added support. For a full list, check out Jio and Airtel pages on the same.
  • If your phone does support WiFi Calling, there will be an option to enable it in the Settings for your phone. On Android, this option is present in ‘Connections’ whereas, for iOS, this option is available under ‘Phone’.
  • Once you enable it, calls will automatically be made using WiFi whenever it is available.


A few key points

  • WiFi Calling is free for STD but paid for ISD at the same rates as VoLTE.
  • You might need to update the software of your phone to get the feature.
