Calls and SMSes from vague and unsolicited commercial companies has been a plague for ages now. A seemingly losing battle, we now just try to find something amusing written in these messages, or play around with the callers, because we've resigned ourselves to an everpresent nuisance. The TRAI has a couple of options to help you out however, via registering with the National Customer Preference Registry. You can register by calling or through SMS. Both the methods are explained below. To register a complaint via phone call, dial the toll free number 1909 and follow the instructions - A. Opting for the 'Fully Blocked Category' involves stoppage of all commercial Calls/SMS.

You can also easily unregister from the system by sending "STOP" to 1909.
