Welcome to the MHD-8100 User’s Manual!

The MHD-8100 is a hardware SMS gateway with eight built-in modems and your own SIM cards, so your messages go out over the mobile network directly from your own infrastructure, with no third-party SMS provider in between.

This manual is the complete reference for the device and applies to all MHD-8100 variants; where behaviour depends on the modem type or the hardware revision, the relevant section is marked with a badge. If your device is still in its box, start with What’s In The Box and then run the Configuration Wizard. Otherwise, use the navigation on the left or the search box to go straight to the topic you need.
