  • Blocked – If receiver mobile number is registered in “Fast2SMS do not disturb” then our system will show status as “blocked”. The image below depicts the delivery status of the SMS in which the number is blocked. In Fast2SMS we can block our number if we don’t want to receive SMS. If a person has activated ‘block your number’ feature then the SMS will not get delivered.

Note : We don’t charge for the SMS in which the receiver has blocked his or her number

  • 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.
