SR-Board-288-3G/4G
SR-Board-288 — a new-generation compact device for remote management of 288 nano-SIM cards. Thanks to built-in antennas, the device has minimal dimensions while maintaining full functionality.
The model is equipped with 3 universal 3G/4G modules that support voice communication. Cards are installed via a Push/Push mechanism, and the display and buttons allow switching modes directly from the device.
Audio headset connection for voice calls is supported (in the 3G version).
Control and Integration
SR-Board-288 operates autonomously via Wi-Fi and can be controlled from anywhere in the world through the web interfaces SR-Navigator and SimFolder.
Supports a modern event-driven control model: the server sends a command to activate a card, and the device itself monitors the status and transmits events back. This simplifies integration and reduces the load on your software.
3G SIM5320 modules supporting voice communication are installed by default. Optionally, you can choose 4G SIM7600 modules from the dropdown list on the product page.
