Government-owned Bharat Sanchar Nigam Limited (BSNL) has become the first telecom operator to launch a satellite-to-device service in India. BSNL is collaborating with the US-based satellite communications company Viasat to provide this service. The companies successfully demonstrated satellite-powered two-way messaging services for attendees at the India Mobile Congress 2024 in October.

BSNL's Satellite-to-Device Service
"BSNL launches India's 1st Satellite-to-Device service! Seamless connectivity now reaches India's remotest corners," posted the Department of Telecommunications (DoT) on its official X handle (formerly Twitter) along with a video explaining the service on Wednesday.
Viasat had previously stated that it is working with partners, including BSNL in India, to expand satellite services for consumer and Internet of Things (IoT) devices globally.
Collaboration with Viasat
In the trial, Viasat demonstrated two-way messaging and emergency SOS messaging using a commercial Android smartphone enabled for non-terrestrial network (NTN) connectivity. Messages were sent nearly 36,000 km to one of Viasat's geostationary L-band satellites.
The new technology follows new global mobile 3GPP release 17 standards, which are currently being adopted by satellite operators, telcos, handset and chipset manufacturers.

Direct-to-Device Connectivity
During the demonstration at IMC, Viasat explained that direct-to-device connectivity is a new technology that allows everyday devices—such as mobile phones, smartwatches, or cars—as well as industrial machinery and transport operators to connect seamlessly to both terrestrial and satellite networks.
However, the telecom department, BSNL, and Viasat have yet to disclose specific details about the service, including availability, accessibility, applicable regions, and service usage fees.
