Indian mobile customers would finely get some relief from telemarketers as the TRAI has issued a notification making it compulsory for the companies to offer ‘Do Not Call’ registry to their subscribers.

Addition to this registry would enable the mobile customers to avoid getting calls from attending unsolicited promotional calls and messages.

Customers would be able to join the service online and also by sending SMSs to their customer care centers. The service providers would not be allowed to make any promotional call or messages to these numbers.

Telecom Regulatory Authority of India (TRAI) said in a statement that such a service is already provided by all the players in the market except for BSNL.

The TRAI has also told the mobile companies to provide a special ring back tone to the calling party when a person is on roaming. This would benefit them as the caller would realize that the person he/she is calling is not in his hometown.

TRAI said in its statement: “Mobile users can activate this facility before going abroad. This will enable minimizing calls when on international roaming, if the calling party exercises restraint.”
