Tata Communications announced on Wednesday that Indian state telco Bharat Sanchar Nigam Limited (BSNL) is using its eSIM subscription management platform to power its newly launched eSIM services for millions of subscribers across India.

The GSMA-accredited Tata Communications MOVE platform – delivered by subsidiary Tata Communications Collaboration Services – enables BSNL to provision 2G, 3G and 4G connectivity services remotely through a secure QR code, eliminating the need for a physical SIM card.

Users with devices supporting dual-SIM functionality can use an eSIM alongside a physical SIM, making it easier to connect with local operators while travelling abroad, Tata said.

BSNL chairman and MD A Robert Ravi said the launch of pan-Indian eSIM services is a big step towards enhancing customer experience and future proofing mobile connectivity in India with increased convenience, flexibility and security in cellular services.

“With Tata Communications’ strong connectivity experience and forward-looking innovation, we are enhancing the flexibility, security, and efficiency of mobile services for citizens across India,” he said in a statement.

BSNL soft-launched its eSIM services in the Tamil Nadu circle in August. This past weekend, the telco unveiled its nationwide 4G network – the first to run on a fully indigenous 4G stack developed by Tata Consultancy Services, the Center for Development of Telematics (C-DOT) and Tejas Networks.
