Who loves spam? Whether it is in the form of SMS or phone calls. We all hate spam and we all get spam. There are ways of blocking spam and each operator has various methods to enable DND (Do Not Disturb) on your phone no.
TRAI (Telecom Regulatory Authority of India) has come up with a wonderful app called – DND. It allows you to register for DND with your Operator / Service Provider to avoid Unsolicited Commercial Communication (UCC)/ Telemarketing Calls / SMS. It’s a simple process, which not only blocks spam but also allows specific transactional messages to come through e.g. you can allow Banking (or several other category) Messages to come through.
Apart from allowing you to activate DND on your phone, the app also helps you file complaints for any message that may slip through and follow through on your complaint.
This is a must have app on all mobile phones in this era of spams!
