Enhanced Connectivity in Weak Signal Areas
VoWiFi enables customers to make and receive voice calls and messages over Wi-Fi networks, ensuring clear and reliable connectivity where mobile signals are weak—including homes, offices, basements, and remote locations.
The IP Multimedia Subsystem (IMS)-based service supports seamless handovers between Wi-Fi and mobile networks. Calls are made using customers’ existing mobile numbers and phone dialers, eliminating the need for third-party applications.
Rural Coverage Breakthrough
The service proves particularly beneficial in rural and remote areas where mobile coverage may be limited. Provided a stable Wi-Fi connection is available—including BSNL Bharat Fiber or other broadband services—customers can enjoy uninterrupted voice communication.
This development addresses connectivity challenges in underserved regions, bridging the digital divide and enabling reliable communication for millions in previously hard-to-reach areas.
Network Congestion Relief
VoWiFi helps reduce network congestion by offloading voice traffic from cellular networks to Wi-Fi infrastructure. This optimization improves overall network performance during peak usage periods while maintaining call quality.
The service is offered completely free of cost, with no additional charges for Wi-Fi calls beyond standard plan tariffs. This zero-cost implementation makes advanced calling technology accessible to all BSNL subscribers regardless of their plan tier.
Network Modernization Milestone
The nationwide VoWiFi launch represents an important step in BSNL’s comprehensive network modernization program. The initiative demonstrates the state-run telecom operator’s commitment to improving connectivity across India, especially in underserved areas.
BSNL continues investing in infrastructure upgrades, including plans to add 23,000 new 4G sites while preparing the network for eventual 5G transition. The VoWiFi rollout complements these expansion efforts by maximizing existing infrastructure utility.
How VoWiFi Works
The technology routes voice calls through available Wi-Fi networks instead of cellular towers. When users move out of Wi-Fi range, calls automatically transition to mobile networks without dropping, ensuring continuous communication regardless of location.
This seamless handover capability distinguishes VoWiFi from traditional internet calling apps, providing reliability and integration with standard phone functionality.
