TRAI asks Tata Tele to refund unspent balance of users

Telecom regulator TRAI has directed Tata Teleservices to refund the unspent balance of its pre-paid mobile subscribers as well as the security deposit of its postpaid users in 16 circles. This comes after the company had surrendered administratively-allocated spectrum in these circles. The company has been asked to submit a compliance report by August 20.
