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.

Another Gateway Product from the Lithuania-based Company - Teltonika, the TRB145 is a network gateway with serial communications port, that can connect and control your RS485 devices with ease. This compact and powerful IoT Gateway enables seamless integration of RS485 serial communication devices with cloud platforms. You can configure Serial OverIP to connect two serial-based devices together and manage/monitor them with ease.
