Telecom tribunal TDSAT on Wednesday sought responses from operators over a petition filed by the Telecom Users Group seeking uniformity in the prepaid plans offered by operators.

A TDSAT bench headed by Justice S B Sinha asked the service providers and regulator, TRAI to file their responses within a month. TDSAT passed the order after converting a letter written by the Telecom Users Group into a petition.

The Telecom Users Group had complained that prepaid mobile tariff plans are bewildering and has become tools of exploitation for consumers by telecom operators. It talked about bringing more transparency in prepaid mobile tariff by introducing "One Plan for All" which would remove tariff anomaly and help customer save their money.

"Even though most of the telecom operator have switched to per second per paisa call which has resulted to a competitive tariff, but still due to tariff anomaly and top up charge coupon, they create confusion" the Telecom users Group said.
