Tata Tele to bill roaming calls per second

Mumbai: Mobile services provider Tata Teleservices Ltd on Sunday extended its per-second billing scheme to roaming calls as well, as the tariff war in the world’s fastest growing wireless market heats up.

On Friday, industry leader Bharti Airtel Ltd introduced a new billing plan that cut mobile roaming rates by nearly 60%, depressing the company’s shares.

From Monday, Tata Teleservices, 26% owned by Japan’s NTT DoCoMo Inc., will charge one paisa per second for both incoming and outgoing calls made while roaming across the country, irrespective of the network used, the company said.
