Messages that originate from a Nigerian Number are very likely to be blocked. The networks have stated that they prefer to receive with an Alpha Sender. Although we have not yet seen any problems sending from an international number, we do advise to use an Alpha Sender in the FROM field.
Our direct connection with Etisalat (62160) supports only alpha senders, all numeric senders will be overwritten with "NXSMS".
Our direct connection to Airtel (62120) support dynamic senders.
Our direct connection with MTN (62130) supports only alpha senders, all numeric senders will be overwritten with "NXSMS".
Our connection to Glo (62150) support dynamic alpha senders, however there are chances that the alpha Sender ID would be replaced to ensure delivery.
Delivery to CDMA networks in Nigeria is not officially supported:
Messages sent to CDMA operator Starcomms Nigeria will not return Delivery Receipts, but only acknowledgment of message reception (submit_sm_resp) by the carrier. Furthermore, if a number lookup is performed will appear as being roaming outside Nigeria.
CDMA operator Visafone Nigeria (62125) does not provide Delivery Receipts. You should not expect Final status notifications for messages to this Operator.
