Mumbai: To reach out to the retail voice customers directly, Videsh Sanchar Nigam Ltd (VSNL) has tied up with Tata Teleservices Ltd (TTSL) to launch STD/ISD prepaid calling cards under the brand name “Hello Duniya.” 

These cards will enable customers to make STD and ISD calls from any Tata Indicom fixed wireline, wireless or payphones across all TTSL’s circles without having to activate the facility on the telephone. 

The telecom service provider also said that it would come out with a global calling card enabling customers to call India and other countries from destinations across the world, a VSNL release said.
