Platform capabilities

Everything you need to send messages at scale

Direct operator connections, intelligent routing, and developer-first tooling.

Direct SMPP connections

Every message routes through direct connections with Vodacom, Tigo, Airtel, and Halotel. No aggregator middlemen means faster delivery and higher success rates.

Automatic failover routing

If a primary delivery path is congested or unavailable, our engine automatically reroutes through an alternate path without any action from your side.

Real-time delivery receipts

Get detailed status codes for every message: queued, sent, delivered, failed, or expired. All statuses are pushed to your webhook URL in real time.

Official SDKs for 5 languages

Production-ready SDKs for JavaScript/Node.js, Python, PHP, Java, and Go. Install, initialize, and start sending in minutes.

TCRA-registered Sender IDs

Verified alphanumeric Sender IDs so recipients know exactly who is contacting them. Builds trust and improves open rates.

Generate and refine message content with AI-powered magic write. Input your intent and get optimized copy that fits within character limits.
