Telecom regulator TRAI has said that from first of October unwanted calls and SMS's will get stopped. TRAI Chairman J S Sarma said at a function in New Delhi that a new Telecom regulatory policy will come into force from October.

Mr. Sarma asked leading telecom service providers, including Bharti airtel, Vodafone and Idea, to explain the rationale behind hiking tariffs by up to 20 per cent. He said, they have sent letters to all the companies which have recently hiked tariffs seeking justifications for the reasons as to why they have hiked the tariffs. 

AIR correspondent reports, most of the companies cited inflationary pressure in the country as being responsible for the tariff hike.
