Frequently Bought Together
Iot SIM Cards, have some advantages over regular SIM cards for certain applications. These type of SIMs are designed to connect devices (including Routers/Gateways) to the Internet of Things, which is a network of physical objects that can collect and share data without human intervention. Regular SIM cards, on the other hand, are mainly used for voice and data services on your phone. They are bound to one carrier network, which can limit your coverage and increase your costs. They also have dynamic IP addresses, which can make it harder to access and control your devices remotely.

The TRB255 is a Dual-SIM 4G/LTE Gateway, ideal for industrial equipment integration and application. Supports Auto-Failover, VPN, I/O ports and various mounting options.

It’s another versatile and robust member of the TRB gateway family from Teltonika Networks, which supports various VPN protocol that includes but not limited to; OpenVPN, ZeroTier, WireGuard, and more. This Teltonika gateway is perfect for Machine-to-Machine (M2M) application, as well as, for IoT applications, due to its Access Control flexibility (access control of TCP, UDP, ICMP packets, MAC address filter) and stupidly easy to integrate with various legacy industrial devices/equipment, with modern solutions and applications via RS232, RS485 and Ethernet interfaces.

This TRB model, undoubtedly has an extensive networking and industrial features, such as; SMS control, RMS (Remote Management Software), Pre-configured Firewall, Modbus, SSHFS and several other useful features.
