Troubleshooting Failed SMS Deliveries

Failed SMS deliveries can happen because of invalid numbers, not enough SMS credits, unapproved sender IDs, or temporary gateway issues.

Check delivery reports

Open campaign details or API reports to see message status: sent, pending, failed, or delivered.

Check SMS credits

A send is refused when available credits are lower than the message parts. Buy a bundle and retry. Credits already held by a campaign are not available until that campaign finishes or you cancel it.

Confirm sender ID approval

Messages using unapproved sender IDs are blocked. Ensure your brand sender ID is approved before sending.

Review phone numbers

Invalid or landline numbers fail validation. Re-import contacts or run API validation before retrying.

Gateway failover

Notifymore routes through multiple Ghana gateways. Temporary provider issues may resolve on retry via failover routing.
