The term DND means Do Not Disturb. It is a service that was introduced by the Nigerian Communication Commission
{NCC} to enable full blocking mode on phone numbers with or without the consent of the subscribers on their network.
The implication of this is that, all bulk SMS that is sent to phone numbers that have been placed on Do-Not-Disturb
by the network operators will be on the Rejected delivery status.
This is a general directive affecting unsolicited messages (Bulk SMS) only, phone to phone messages and bank alerts
are not affected.
