In a boost to Reliance Jio, which is offering life-time free voice calling service, telecom regulator Trai has held that tariff plans of the new player are compliant to existing rules and not discriminatory.

Incumbent operators Bharti Airtel, Vodafone and others approached Trai against free call service being offered by Reliance Jio, calling the tariff plan predatory, discriminatory and non-compliant to present rules.

Telecom operators are required to pay 14 paise per minute for each outgoing call from their network to the operator on whose network the call finally lands.

Reacting to the Trai letter, RJio in a statement said, “This (Trai’s letter) clearly establishes the fact that all the tariffs offered by RJIL are in compliance with the prevailing regulations. A key feature of RJIL’s tariff packs is free voice calling for Local, STD and National roaming for all times.”

Besides this, it is offering unlimited free 4G mobile broadband till December 31.

The revised offer of free services by Reliance Jio has been limited to 90 days i.e. December 3, 2016 and therefore is consistent with the guidelines on promotional offers,” Trai said in an order.

Reliance Jio said that the free service, including unlimited mobile data, will be available for its subscribers till December 31.

“As per RJIL’ s filing with the TRAI, the Jio Welcome Offer will be available to all the customers for subscription till December 3, 2016. RJIL wishes to reconfirm that JWO benefits of free unlimited voice and data will continue to be available to all subscribers till December 31, 2016,” the company said.
