Many people suffer from the unwanted marketing messages and calls made by the mobile network operators. These messages and calls are extremely annoying, and there is no way proper information on how to activate this service. This service was formerly called DND (Do Not Disturb), which now transformed to NCPR (National Consumer Preference Register) by the TRAI (The Telecom Regulatory Authority of India). Previously, people who subscribed to DND had chances to receive the unsolicited promotions calls from their mobile network operators. With NCPR, the chances of receiving these unwanted messages is almost zero.

According to NCPR, a mobile customer in India can stop all the unwanted marketing calls and messages whenever he/she wants. This service can give you the option of selecting various options according to your requirement.

All the service providers will have the same set of instructions to register for the do not disturb service. You can activate DND from your mobile by just calling 1909 and selecting the options, or by sending a simple SMS to 1909. This message is similar to all the mobile network operators in India, and check out the various companies and their registration process to start your DND service.
