Wi-Fi calling is the buzz word in the Indian telecom industry right now. Airtel has already launched its Wi-Fi calling service in the country (available only in some areas for now), while Reliance Jio is still testing it in some circles and is expected to announce it very soon. Before getting into details like availability of the service and devices compatible for making Wi-Fi calls. Wi-Fi calling is voice calls made with the help of a Wi-Fi network. It works similar to normal calls but uses Wi-Fi connection instead of mobile network, which often doesn’t work properly in indoors.

What is Wi-Fi calling?
  1. One of the biggest issues mobile phone users are facing these days as far as mobile networks are concerned is call drop. The incidents of call drop have increased drastically in the last few years.
  2. To combat the issue telecom operators are introducing Wi-Fi calling service. Some have already launched the service while others have started testing it. 
  3. Wi-Fi calling basically aims at offering an enhanced and seamless voice calling experience to users even when the cellular network is patchy. Since the service uses stable Wi-Fi connections to make calls, incidents of call drops should not happen.
How Wi-Fi calling works?
  1. The Wi-Fi calling service uses high speed internet connection offered by broadband network to allow users make and receive high definition (HD) voice calls. 
  2. It works similar to WhatsApp calls. Similar to the voice calling apps, Wi-Fi calling allows users to make phone calls, but it doesn’t require them to install an application for it. The service also doesn’t charge the user and consumes very minimal data.
