Recently, Airtel started testing WiFi Calling (VoWiFi) in several cities in India and later officially launched the service. Following Airtel’s launch, Reliance Jio has now started rolling out WiFi Calling facility in Chennai and Delhi-NCR. Several users in Chennai have reported that they are seeing ‘Jio WiFi’ icon or a similar WiFi Calling icon on their smartphones. Although Airtel WiFi Calling worked with all Wi-Fi networks during the testing phase, it is now restricted to Airtel Broadband users. Also, some users have reported that Jio VoWiFi is working with Airtel mobile hotspot too.
