Do Not Disturb 3.0 App is an all-in-one tool that enables users to register their phone numbers under the Digital No Disturb (DND) policy. This is a new version of the app, which has been updated based on the latest policy from the Telecom Regulatory Authority of India (TRAI).

The DND policy is an official policy of the TRAI that has been made to give preference to consumers who do not want to be contacted by telemarketers. The policy also helps to identify and eliminate unwanted advertising.

The app helps users register their phone numbers and get their phone numbers removed from any service provider's database. The app also provides the user with the option of getting the phone number of the person calling them on their phone number.
