If you have been experiencing failed or poor delivery of messages when you send SMS, or if certain numbers do not get your SMS, it is most likely as a result of the creation of DND (Do Not Disturb). Even your own number may no longer be receiving bulk sms if DND was activated on it, with or without your consent!
The DND service was enacted by the NCC (Nigerian Communication Commission) and became effective from 1st July 2016. The service blocks phone lines from receiving bulk sms or promo texts from third parties. However this can be deactivated if one discovers that he is not receiving important messages especially using MTN numbers.
For some GSM subscribers, the service was activated on their lines without their consent. This may be so for those numbers that are not getting your bulk sms. You can encourage your recipients to opt out of the DND service, or activate partially. It is completely FREE of charge! To do so, first text the word STOP from the affected phone to the short code 2442, then text ALLOW to 2442.
Also, bulk sms with some custom IDs may not be delivered. Alternatively, use rUPDATE or rNOTIFY as your Sender ID to ensure delivery.
Note that bulk sms sent to DND numbers are still billed by GSM operators even though it won’t be delivered. But before sending your bulk sms on sms-depot.com, Our system will detect DND numbers and display them for you, automatically excluding them from the send list. You can optionally select them manually to include them back on the send list. We have however received feedback from few of our subscribers that some of the DND numbers manually included may still fail to receive bulk sms sent.
We are working on a solution that will ensure delivery using any custom ID and guarantee delivery to DND numbers through the financial services route though delivery may cost a little more.
