Ensure scalable messaging without Fair Usage Policy limits

The MD300 is a compact, secure messaging solution built for enterprises and government agencies that demand scale.

As a powerful on-premise omni-channel hub, it replaces outdated SIM card–based SMS modems, delivering a protected LTE connection through a single SIM card to your preferred gateway. The MD300 supports number masking and enables high-volume SMS, email and voice broadcasts – all while maintaining compliance, security and performance.

Whether you're building a secure enterprise messaging infrastructure or powering nationwide emergency notifications, the MD300 delivers reliable, scalable communications free from traditional telco restrictions, ensuring you can connect at scale without compromise.


How it works

Conventional SIM card modem solutions are constrained by Telco Fair Usage Policies, which limit SMS broadcast capacity and can result in missed alerts. The MD300 operates outside these restrictions, ensuring that all intended recipients reliably receive every message.
