According to the Telecom Regulatory Authority of India (TRAI) Idea Cellular is the only service provider which has not implemented the unsolicited commercial communications (UCC) SMS complaint lodging module.
On November 5, 2012, TRAI had issued ?The Telecom Commercial Communications Customer Preference? laying down further measures to tighten the framework for controlling inconvenience caused to consumers because of UCC.
As part of the regulations, TRAI has facilitated the easy lodging of UCC complaints through SMS mode by forwarding the UCC SMS to 1909 by appending the telephone number/SMS header and date of receipt of SMS.
