Considerations in choosing a router with sim card slot 4g 

1)Price: due to cost considerations, price is an important factor to be considered by many users. The price is too high, beyond the cost budget, the user can't accept it. Isn't the lower the price, the better? Not really. Unusually low prices mean that the product may not use industrial-grade modules, which can affect stability. It's not possible because the beginning of the purchase cost is very low, and the subsequent maintenance cost is very high, and income is not worth the loss. Therefore, a reasonably priced 4G industrial router is very important.

(2)Stability: the stability of the equipment is very important, which is related to the stability of the entire network data. The device needs to support software reboots and hardware monitors to ensure that there are no problems in running unattended for long periods of time.

3)Extensibility: some 4G industrial routers only have two network ports, and some do not support serial ports. Therefore, the compatibility of subsequent projects should be considered when purchasing. For example, PLC monitoring, in addition to the interface of the PLC itself, can also use the touch screen, as well as video monitoring.

(4)Technical support :4G industrial routers with sim card slot 4g are different from ordinary routers. Uses a lot of network technology, such as VPN and port mapping. If you are not familiar with the network, you may encounter such problems when using it. Therefore, it is very important for the company to be able to provide timely technical support and respond quickly to customers.

(5) Product chip: the industrial grade 4G router supports the -20°to75°operating environment, so the project implementation environment should be considered.
