State-owned telecom operator Bharat Sanchar Nigam Limited (BSNL) has officially announced the nationwide rollout of Voice over Wi-Fi (VoWiFi), also known as Wi-Fi Calling, across all telecom circles in India. With this launch, BSNL customers can now make and receive voice calls and text messages over a Wi-Fi network, even in locations where mobile network signals are weak or unavailable.
The introduction of VoWiFi marks a major milestone in BSNL’s network modernisation programme, reinforcing the company’s commitment to improving digital connectivity, particularly in rural, remote, and underserved regions.
What is BSNL VoWiFi (Wi-Fi Calling)?
VoWiFi is an IP Multimedia Subsystem (IMS)-based service that allows voice calls and SMS to be transmitted over a Wi-Fi connection instead of traditional cellular networks. Users can place calls using their existing mobile number and default phone dialer, without installing any third-party applications.
The service supports seamless handover between Wi-Fi and mobile networks, ensuring uninterrupted communication even when users move between coverage zones.
Key Benefits of BSNL VoWiFi Service
- Clear voice calls in areas with poor or no mobile signal
- Works in homes, offices, basements, and remote locations
- No additional charges for Wi-Fi-based calls
- Reduces network congestion on cellular networks
- Ideal for rural and remote areas with broadband access
- Compatible with BSNL Bharat Fiber and other broadband connections
Free Service for All BSNL Users
BSNL has confirmed that VoWiFi is being offered completely free of cost. There are no extra charges for calls made over Wi-Fi, and standard calling benefits under the user’s existing plan will apply.
According to the Ministry of Communications, the service is expected to significantly improve call quality while easing congestion on mobile towers, especially in densely populated or geographically challenging regions.
Device Compatibility and Activation
The VoWiFi service is supported on most modern smartphones. To activate it, users simply need to:
- Go to Phone Settings
- Enable Wi-Fi Calling / VoWiFi option
- Connect to a stable Wi-Fi network
Once enabled, calls will automatically route through Wi-Fi when cellular signal strength is low.
For confirmation of device compatibility or technical support, users can:
- Visit the nearest BSNL Customer Service Centre
- Call the BSNL Helpline: 1800-1503
Why VoWiFi is Important for India
India’s diverse geography often makes mobile coverage challenging, particularly in hilly, rural, and indoor environments. With VoWiFi, BSNL leverages existing broadband infrastructure to deliver reliable communication, aligning with national goals of digital inclusion and connectivity for all.
This service is especially valuable for users in villages and small towns where broadband connectivity exists but mobile signals remain inconsistent.
