Bharat Sanchar Nigam Limited (BSNL) has rolled out its Voice over Wi‑Fi (VoWiFi) service nationwide starting January 1, 2026. The service, also known as Wi‑Fi Calling, is now available to all BSNL subscribers across every telecom circle in India, aiming to enhance call quality and connectivity even in areas with weak mobile signals.
VoWiFi allows users to make and receive voice calls and SMS using a Wi‑Fi connection, bypassing traditional cellular networks. This is particularly useful in locations such as basements, offices, homes, rural areas, or other regions where network coverage is poor. The service works with any stable broadband connection, including BSNL Bharat Fiber or other internet providers, ensuring uninterrupted communication in so-called “coverage shadow” zones.
The system operates on an IP Multimedia Subsystem (IMS) platform, which enables smooth switching between Wi‑Fi and mobile networks without dropping calls. Users can make calls directly from their regular phone dialer, with no need for third-party apps. Most modern smartphones support VoWiFi, and subscribers may need to activate the Wi‑Fi Calling feature in device settings.
BSNL has made the service available at no additional cost. Calls made via Wi‑Fi are billed under the subscriber’s existing voice plan, meaning users can enjoy improved connectivity without extra charges. The move is part of BSNL’s efforts to enhance customer experience while managing network congestion as the operator continues expanding its infrastructure.
By launching VoWiFi nationwide, BSNL joins other telecom providers like Reliance Jio, Bharti Airtel, and Vodafone Idea that already offer Wi‑Fi calling. This rollout aligns with the company’s broader strategy to modernize its network, strengthen coverage in underserved areas, and prepare for future 4G and advanced network developments.
BSNL’s nationwide VoWiFi service is expected to significantly improve call quality and reliability, particularly in regions with limited cellular connectivity, helping the operator bridge digital gaps while providing seamless communication for its customers.
