BSNL has launched its Voice over Wi-Fi (VoWiFi) service nationwide, enabling customers to make and receive calls and texts using a Wi-Fi connection instead of cellular signals. This aims to improve connectivity in areas with weak or no mobile network coverage, such as villages, remote regions, and indoor locations. The service is available to all BSNL customers and works seamlessly with existing phone dialers and plans, automatically switching between Wi-Fi and cellular networks as needed.
