BSNL Rolls Out Nationwide VoWiFi Service Across India

BSNL has launched its Voice over Wi-Fi (VoWiFi) service across all telecom circles in India, enabling customers to make clearer calls using Wi-Fi networks — especially in areas with weak or no mobile signal.

BSNL Launches VoWiFi Service Across India

India’s state-owned telecom operator Bharat Sanchar Nigam Limited (BSNL) has taken a major technological step at the start of the new year. BSNL has rolled out Voice over Wi-Fi (VoWiFi) or Wi-Fi calling services nationwide across all telecom circles in India.

This service will deliver a reliable voice-calling experience even in locations where mobile networks are weak or unavailable. The primary objective behind this initiative is to improve voice service quality, particularly in rural and remote areas.

What Is VoWiFi and How Does It Work?

VoWiFi is a technology that allows users to make voice calls and send SMS through a Wi-Fi network instead of relying solely on mobile signals. As a result, users benefit from better coverage, fewer call drops, and clearer voice quality.

According to BSNL, the service works using BSNL Broadband, Bharat Fiber, or any available Wi-Fi network.

One key advantage of VoWiFi is that it does not require any third-party application. Customers can simply use their existing mobile number and the default phone dialer, keeping the user experience smooth and simple.

Technology Behind VoWiFi

VoWiFi (Voice over Wi-Fi) is based on IP Multimedia Subsystem (IMS) technology, which enables seamless transition (handover) between Wi-Fi and cellular networks.

When users move from one network environment to another, calls can continue without dropping, thanks to this IMS-based system.

This service becomes particularly effective in situations such as:

• Inside homes and buildings

• Underground spaces

• Large office complexes

• Remote rural areas

All that is required is a stable Wi-Fi connection.

Benefits for Rural and Indoor Connectivity

VoWiFi technology is especially useful in areas where mobile network coverage is weak or unavailable. With this service, users can enjoy:

• Better voice quality indoors

• Access to voice services in low-coverage zones

• Reduced call-drop issues

• Lower congestion on mobile networks by shifting traffic to Wi-Fi

These features make voice services more accessible across challenging terrains and rural regions.

Cost, Availability, and Device Support

BSNL has made VoWiFi service available free of cost, meaning there are no additional charges for Wi-Fi-based calls. Most modern smartphones support the feature. Users simply need to enable Wi-Fi Calling in their phone settings.

For device compatibility queries or technical support, customers may visit the nearest BSNL service center or contact the BSNL helpline at 1800-1503.
