What is NDNC filter & how does it work?

NDNC stands for National Do Not Call registry run by the Govt. of India to prevent unwanted marketing calls or SMS for those who do not want to be disturbed or receive such promotional calls. So if you are running a bulk SMS campaign to unknown numbers, we request you to use our NDNC filter gateway so that NDNC registered users will not receive your SMS.
