Many of us are sick and tired of those unsolicited calls & SMS. While there is a Do Not Disturb (DND) option to block all such calls & SMS, some of us might want to keep getting information about banking or other such products. The Telecom Regulatory Authority of India (TRAI) has a clearly laid down procedure for registering your preference for receiving such commercial communication.
Procedure for Registering your Preference
As a telecom customer, you have the option to either block all commercial calls and SMS or to block only commercial calls while receiving SMS of your choice. For this purpose, you have to register your preference. Preference can be registered by
You can register for the Fully Blocked category in which No Commercial Call or SMS will be allowed or for the Partially Blocked category.  If you opt for the Partially Blocked category, you will not receive any commercial call but will receive SMS on subject(s) that you opt for.
The various subjects in the partially blocked category are the following
Registering Through IVRS or Customer Care
Once you dial 1909, listen to the instructions and choose one of the following for registration of the preference:
You could ask the customer care executive for registration of your preference i.e. whether you would like to register in the fully blocked category or the partially blocked category.
The customer care executive will ask you to exercise your preference if you opt for the partially blocked category. You can opt for one, or a combination of some, or all the subjects. The customer care executive will confirm your preference(s) and register the same. You will get an SMS confirming the preferences exercised by you along with your unique registration number.
Similar process has to be followed for registering your preference through IVRS.
Registering Through SMS
You can register your preference(s) for commercial communications by also sending an SMS to 1909.
The procedure for opting for various categories is the following
You can also opt for multiple preferences from categories send SMS START <option1, option2, option3,…>  to 1909. For e.g., START 1,2
Please remember that Preference ‘0’ will always suppress other preferences. If ‘0’ is sent with along any other customer preferences, it will be treated as a fully blocked preference. For example, START 0,2,3  will be considered a fully blocked option.
On receipt of an option exercised through SMS, the telecom service provider will send an SMS to confirm the options exercised. You have to send a confirmation SMS so that options exercised are implemented. On getting the confirmation SMS, the telecom service Provider will register your preference and send you an SMS indicating your preferences along with your unique registration number.
Registering a Complaint
