State-owned telecom operator BSNL has kicked off 2026 by rolling out free Voice over WiFi (VoWiFi) services across India, marking a significant step in improving connectivity for its users. The service allows customers to make voice calls and send messages over any stable WiFi network while retaining their existing mobile number, without the need for additional applications.
VoWiFi is particularly beneficial in areas with weak cellular signals, such as elevators, thick-walled buildings, basements and remote locations. The service seamlessly switches between WiFi and cellular networks, ensuring uninterrupted communication as users move in and out of network coverage zones.
The rollout aligns with BSNL’s broader modernisation strategy, which includes the expansion of its 4G network to nearly 97,000 sites nationwide. By enabling calls over WiFi, BSNL is also easing congestion on mobile towers while significantly enhancing indoor coverage and call quality.
With this move, BSNL aims to strengthen its competitive position against private telecom players like Jio and Airtel, both of whom already offer WiFi calling services. The initiative reflects BSNL’s focus on improving customer experience while leveraging existing broadband infrastructure.
Activating VoWiFi on BSNL is simple for most modern smartphones. Users with a BSNL 4G SIM can enable the feature directly through their phone settings, provided the device supports WiFi calling. Once activated, calls and messages automatically route through WiFi whenever available, switching back to the cellular network when WiFi is unavailable.
As BSNL continues to expand its network and introduce customer-friendly digital services, the nationwide VoWiFi rollout represents another step towards bridging connectivity gaps and strengthening reliable communication across urban and rural India.
