Tata Teleservices, with 36 million subscribers as May 31, got the GSM license for 19 circles and spectrum in 18 circles.

With a 'pay for what you use' model, a pulse of one second and pricing of one paisa per second, Tata Docomo promises to bring a paradigm shift in the telecom experience for its customers.

'For other operators, a call of one second above two minute duration is a call for three minutes, but for us it will be 121 seconds,' Sardana said, and maintaining that 18 to 25 percent of subscribers pay more than what they use.
