Bulk SMS that reaches every network in Nigeria

The most common cause is the Do Not Disturb register: the networks block promotional traffic to DND-active numbers, and no provider can override that. Transactional messages travel a separate corporate route and are not filtered as marketing. Other common causes are an unapproved sender ID, a number that is not in valid +234 format, and a handset that was unreachable until the message expired. The delivery report names which applied.

You can build and test in sandbox immediately. A production send with an unapproved sender is refused rather than delivered under another name. Alphanumeric sender IDs must be registered per network, we handle the submissions, and the dashboard shows the status of each.

Most messages are handed to the network within seconds. Delivery to the handset is the network's decision and depends on coverage and whether the phone is on: an unreachable handset is retried until the message expires. Your delivery report updates as each network confirms.

No. An alphanumeric sender ID is one-way, and Sendozi does not receive inbound SMS, so a reply - including a STOP reply - is not captured. Put a contact route in the message for anyone who needs to respond or opt out, and record opt-outs on your suppression list.

No. The SMS API accepts Nigerian mobile numbers in +234 format only, and anything else is rejected. There are no international routes and no international pricing.

Yes. Import a CSV, map the columns once, and the list is ready for campaigns and personalisation. Normalise numbers to +234 format first - local 0-prefixed numbers are rejected. You are responsible for having consent to message the people on the list.
