TRAI banned 22,769 subscribers over unsolicited calls and SMS to users under NDNC
This banned advertisers to call and SMSs to user registered under the Do Not Disturb (DND) Registry.
The DND blocked all kinds of advertisements and promotions from reaching a user. But it was with the National Customer Preference Register (NCPR) that mobile consumers were able to opt in for the kind of advertisements they want to receive. And TRAI has revealed that since its coming into effect and until the 29th March 2012, a total of 161.66 million customers have registered their preference on the NCPR.
