BSNL is testing a new service that lets you send messages without a SIM: Here’s how it works

At the recently concluded Indian Mobile Congress, the government-owned telecom operator BSNL unveiled its new logo and slogan and announced the launch of seven new services, one of which might let you make phone calls without a SIM card.

Dubbed “Direct to Device”, BSNL says that the connectivity solution “converges satellite and terrestrial mobile networks to deliver seamless, reliable connectivity.” Developed in collaboration with Viasat, the network operator recently showcased satellite-powered two-way messaging services to attendees at the Indian Mobile Congress.
