In a move to try and curb the pesky messages that you keep getting on your phone, the Telecom Regulatory Authority of India (TRAI) on Monday said that concessional rates offered by the mobile operators would be applicable for a maximum of 100 SMS per day.

Beyond the set limit, the users would have to pay at least 50 paise for every sms they send. TRAI has asked the operators to implement this order in the next 15 days.

It is interesting to note that last week, the telecom minister Kapil Sibal himself showed his displeasure over these unwanted SMS and said that, "Every two minutes I get such SMS."

While releasing the Telecom Commercial Communications Customer Preference (tenth amendment) Regulations 2012 and Telecommunication Tariff (Fifty Fourth Amendment) Order, 2012, N Parameswaran, Principal Advisor (CA & IR) said, " To prevent unregistered telemarketers from misusing such SMS packs or tariff plans for sending bulk promotional SMS, a price restraint has been placed on sending of more than 100 SMSes per day per SIM at a concessional rate."

" While the subscriber is free to send SMSes beyond this number, all such SMSes sent beyond 100 SMS per day per SIM shall be charged at a tariff of minimum 50 paise", he added.

The operators have also been directed to ensure that a maximum of 200 commercial SMS are sent within an hour from a single number/source.

At present, almost all the mobile operators have special tarriffs that enable the users to send unlimited free SMS or as cheap as 1 paisa per SMS. Such tariff plans enable the unregistered telemarketers to send pesky SMS'es to customers.
