The company had earlier rolled out the services in two circles — Maharashtra & Goa and Kolkata, in December 2020. According to a tweet by VIL, the service can now be accessed by both pre-and post-paid subscribers across these four circles.

Tech for 4G services
Voice over WiFi (VoWiFi) is hailed worldwide as the technology that keeps users connected even without a mobile signal. Commonly referred to as WiFi calling, VoWiFi eliminates mobile blackspots for users by making it possible to make and receive calls over WiFi or wireless internet connections.
The service also doesn’t require mobile networks or SIM cards to make the calls. Further, the receiver doesn’t need to have WiFi calling facilities. Calls can be accessed on a Voice over Long Term Evolution (VoLTE, the technology for 4G services) handset. Another benefit is that users can seamlessly move from VoLTE to VoWiFi without the call getting disconnected.
In a move to take on over-the-top players who have been eating into their revenues, Bharti Airtel and Reliance Jio Infocomm also launched VoWiFi services. While Airtel launched the services across all the circles in 2019, RJio launched voice and video over WiFi in January 2020.
In 2018, the Department of Telecommunications approved voice calls over a WiFi network to improve connectivity, especially in rural areas.
