Many people don‘t know much about the role of IoT SIM cards when using industrial routers. Is an IoT SIM card a necessity for industrial routers? Today, we are here to provide you with a comprehensive analysis.

1. The role of IoT SIM card
The IoT SIM card is the bridge between IoT devices and the network. It helps devices connect to the Internet through communication protocols such as GSM, CDMA, and 4G. As the core device of IIoT, industrial routers also need to rely on IoT SIM cards to work properly.

2. The relationship between industrial routers and IoT SIM cards
Industrial routers need to be connected to the operator‘s network through an IoT SIM card to support remote control, data upload and monitoring functions of the device. Without an IoT SIM card, industrial routers cannot communicate with the network and devices cannot function properly.

3. Types of IoT SIM cards
GSM/SIM card: suitable for areas with good signal coverage and low cost.

4G IoT card: supports high speed and low latency, suitable for high-density scenarios.

NFC IoT card: No need to insert the device, supports contactless communication, and is easy to operate.

4. Summary
Industrial routers require an IoT SIM card to function properly, and the IoT SIM card is the core for connecting to the industrial IoT. Choosing the right IoT SIM card can ensure the stability and performance of the industrial router.
