BSNL’s Direct-to-Device Satellite Service For SIM-Less Calling: Key Things About The Game-Changing Service

Users may now send and receive messages and make calls without a SIM card or network connection thanks to the debut of India's first Direct-to-device satellite communication by Bharat Sanchar Nigam Limited (BSNL). The revolutionary service offered by BSNL's satellite-based connection, which could compete with Elon Musk's Starlink, attempts to close the connectivity gap in isolated locations where conventional cellular networks fail. 

To introduce the service, BSNL has partnered with Viasat, a US-based communications provider. It was first announced and showcased at the Indian Mobile Congress (IMC) 2024. The Department of Telecommunications (DoT) announced the formal launch through a post on X.

The BSNL Direct-to-Device satellite service is a satellite-based connection solution that allows consumers to access network services in areas where cellular or Wi-Fi networks are not available. This service transmits signals directly from satellites in orbit to ground-based equipment.

BSNL's service, which has been created with Viasat's geostationary L-band satellites and uses Non-Terrestrial Network technology allows two-way communication between devices on Earth and satellites located 36,000 kilometers above the ground. This ensures reliable connectivity without the need for ground-based cell towers.

People who live in rural and isolated areas where it can be difficult to maintain cellular infrastructure will find the Direct-to-Device satellite service particularly helpful. People can stay connected when they travel to remote locations thanks to satellite connectivity.

Emergency communication services are provided by the Direct-to-Device satellite service. Users can send SOS messages or make emergency calls directly via satellite when cellular or Wi-Fi networks are not available. For travelers, adventurers, and people living in isolated places, this feature offers a vital safety net.

UPI payments may potentially be supported by the Direct-to-Device satellite service. This could enable people in underserved or rural areas to make digital transactions without having internet access.

The service enables two-way messaging as users can send and receive messages over the satellite network.
