What's included
Everything you need
to send great SMS.
One endpoint handles transactional, bulk, and OTP SMS — with DND routing, delivery receipts, and webhooks included at every plan level.
Transactional SMS
Send time-sensitive messages — OTPs, order confirmations, payment alerts — with priority routing that bypasses DND queues.
Bulk & Campaign SMS
Reach thousands of contacts in a single API call. Schedule campaigns, personalise with variables, and track delivery per recipient.
Custom Sender IDs
Send from your brand name instead of a short code. Register sender IDs per country — we handle the local operator approvals.
Number Lookup
Validate a phone number before sending — check if it's active, on DND, and which network it belongs to. Reduce wasted sends.
Smart routing
Africa-specific
routing logic.
Every SMS runs through a 5-step pipeline designed for African operators — DND resolution, network failover, and local compliance checks — before your message ever leaves our infrastructure.
Automatic DND (Do Not Disturb) bypass for transactional messages
Multi-operator fallback — if MTN fails, we try Vodafone, Airtel & others
Local short-code pools and sender ID registration per country
Real-time delivery receipts via webhooks within 200ms
Unicode and GSM-7 auto-detection with smart message splitting
