More on Bulk SMS Sender ID's

We cannot overemphasize the restrictions and policies that have rocked the SMS industry in recent years. The DND issue was just the beginning of what is fast becoming a stringent and controlled bulk SMS industry, thanks in no part to the increase in spam and scam messages. 

The network operators with the support of the NCC are now taking bulk SMS from an individual level to more of a corporate service for firms and businesses. Because of this, it is now mandated that all Sender IDs used to send bulk SMS be registered with all GSM operators (MTN, GLO, AIRTEL, ETISALAT).

When Sender IDs are not registered on the operators’ portal, SMS sent with such Sender IDs are changed automatically by the GSM operators to a default one (For Example “Bulk SMS”). Without this change, the SMS will fail completely while you will still be charged for it.

For this new development, we will forward your Sender IDs for registration on form our end. Please, forward your list of regularly used sender ID’s to us on: This email address is being protected from spambots. You need JavaScript enabled to view it.. Registration takes 5-7 days.


  • Avoid sending unsolicited and scam related SMS from your account, as Sender IDs with such records are banned completely from being used in delivering bulk SMS.
  • The operators also require that the Sender ID for registration should be used regularly, most especially for corporate information. The reason being that Sender IDs used sparingly gets removed from the database eventually.


We sincerely apologize for the inconveniences this new development might cause you. We assure you that as always, we are on top of this situation and already making progress with getting as many IDs registered as possible. We advise that you please desist from sending unsolicited SMS from your account (ensure your recipients want to hear from you), and also use your Sender ID as often as possible to ensure it is not removed from the database. In the meantime, you can also include your Sender ID in the body of the message probably as a signature at the end pending when your Sender ID is registered.


Thank you for your continued patronage.
