  • DND – The DND (Do Not Disturb) status only comes under the promotional route as the Promotional route doesn’t allow sending SMS to DND number, so all DND numbers show this status and money will not be deducted. If you want to send SMS on DND number then use transactional route.

The below image shows the delivery report of an SMS sent to DND number.

Note: We don’t debit the charges if the SMS is sent to DND numbers from Promotional route.
