Why pay per message?
Own your infrastructure.

Traditional SMS providers charge you 100x the actual cost. Reclaim your budget by using the mobile plan you already pay for.

Zero Fees

Send unlimited messages for a fixed monthly cost (your SIM plan). No more scaling surprises at the end of the month.

Smart Routing

Connect multiple devices and SIMs. The system automatically routes messages to available devices with the best signal or quota.

Developer First

Built by developers, for developers. Clean REST APIs, Webhook events, and SDKs for Node.js, Python, and PHP.

Works Everywhere

Whether you are in Mozambique, Brazil, or Portugal. If your phone has signal, your business is online. Stop relying on country-specific aggregator limitations.
