SR-Board-288-3G/4G

SR-Board-288-3G/4G is a compact electronic SIM aggregator of the new generation designed for up to 288 nano-SIM cards.

By incorporating built-in modem antennas, the device’s dimensions were significantly reduced while retaining all essential functions.

SR-Board-288 is equipped with three 3G/4G SIMCom modems. SIM cards are easily inserted and extracted using the push/push mechanism, and the built-in display and buttons allow for swift changes to operating modes directly on the device.

For versions with 3G modems, you can optionally connect an audio headset for voice calls.

Management and Integration

SR-Board operates completely autonomously, powered by an integrated processor and Wi-Fi internet connection. Administration is conducted remotely via web panels such as SR-Navigator or SimFolder, accessible from any PC, tablet, or smartphone.

The device utilizes a modern API specifically tailored for practical applications. Though standard AT commands continue to be supported, this integration method is now considered outdated. Instead, an event-driven management model is applied: for instance, the server sends a command to connect a specific SIM card number, and the aggregator then automatically performs all necessary actions, tracks connection status, and relays incoming SMS messages and other events back to your software. This drastically enhances interactivity and minimizes server strain.

SR-Board-288-3G/4G represents a dependable and highly functional solution for professional SIM card management across 2G/3G/4G networks.

Important! By default, the device ships with 3G SIM5320 modems, which support voice calls. Alternatively, upon request, you can opt for a configuration with LTE-compatible 4G SIM7600 modems.
