Since that day, any phone number on the DND list will stop to receive bulk SMS. The introduction of the DND service became imperative due to numerous complaints to NCC from subscribers.
You might wonder ‘but I never subscribed to such service’. Some subscribers were actually placed on DND list by default. To opt out of the service and start receiving bulk SMS, you will need to (1) text STOP to 2442 then (2) text ALLOW to 2442.
Messages sent to phone numbers on DND are still billed by the operators but not delivered. To prevent such losses, SmartSMSSolutions has developed a powerful infrastructure that helps filters out phone numbers on DND and dead phone numbers before you send your messages. This is the first and only one in the country at the moment.
This feature has been embedded on the Send SMS page and you start to take full advantage of it now.
