Due to the new DND (Do-Not-Disturb) policy from NCC (Nigerian Communications Commission), some mobile network operators now block incoming bulk sms on their subscribers' lines.
So if you are experiencing any trouble receiving sms on your line (especially MTN lines), this is what you should do:
— Text "STOP" to 2442 and after receiving a response, follow the next step
— Text "ALLOW" to 2442 to opt out of the DND (Do-Not-Disturb) Feature
After following these steps, you should start receiving sms once again on your line(s).
