The TRAI DND app (officially TRAI DND 3.0) is a mobile application developed by the Telecom Regulatory Authority of India (TRAI) to help mobile users in India combat Unsolicited Commercial Communication (UCC), which includes unwanted telemarketing calls and spam SMS.
📱 Key Functions of the App:
- DND Registration/Preference Setting: It allows you to easily register your mobile number for the Do Not Disturb (DND) service, also known as the National Customer Preference Register (NCPR). You can choose to:
- Fully Block all commercial communication.
- Customise your preferences to block specific categories (like Real Estate, Education, Health, etc.) while allowing others (like bank alerts).
- Complaint Registration: You can quickly and easily report specific unsolicited commercial calls or SMS messages you receive to your telecom service provider for action.
- Complaint Status Tracking: You can check the status and see what action has been taken on the complaints you have filed through the app.
- Intelligent Spam Detection (for SMS): The latest version includes a feature to help you identify and report spam SMS.
- Crowdsourcing: It gathers data about offending numbers from users to speed up the detection and action against unregistered telemarketers.
In short, it acts as a user-friendly and direct gateway to enforce your right to not receive unwanted promotional calls and messages.
