1.Industrial router 4g is IOT wireless communication router that uses public networks to provide users wireless long-distance data transmission function, it is durable device can connect two or more networks, can transmit signals to the required ports only, price is more expensive than the enterprise router, but functions are stable and powerful. Ordinary sim card router 4g are relatively cheap, the advantage is that it is suitable for large-scale enterprise network connections and can use complex network topology, load sharing and optimal path.

2.Most of industrial router 4g are used for data transmission and other functions, maybe hundreds or more, so the requirements on forwarding performance and wifi capacity of the router is very high if so many people use the wireless networks at same time. But ordinary sim card router 4g has limited forwarding performance and wifi capacity, small coverage, signal strength is low, low density.

3.Industrial router 4g generally have multiple security services and richer routing protocols such as policy routers, static routers, SNMP,  unified management protocols etc., 4g industrial router can ensure the operation of network safely and prevent user data from being stolen with these protocols.

4.Industrial-grade product design is more suitable for long time continuously using. Ordinary 4g router has lot of time to rest as it is normally not work so long time. But industrial router 4g normally work 24 hours all day long, so the requirements for the design is very high.

The main difference is industrial between industrial router 4g and sim card router 4g, industrial router 4g can use outdoor in harsh environment.
