DND Services - Android Apps on Google Play
DND (Do Not Disturb) Services app helps smart phone users to register their mobile number under DND to avoid Unsolicited Commercial Communication(UCC)/Telemarketing Calls/SMS. After registration if telecom subscriber still receives any UCC via SMS or call, then this app will facilitate users to register complaint with their respective tele-service provider. The interface of the app is very user friendly and does not require much of the user intervention. Users can also check their Registration Status and Status of Complaints (Call/SMS). Some options of this App will require internet connection.
