How can we use SIM card in a router?

Nowadays mobile phone is one of the most common tool of communication. It uses SIM card to access internet. But have you think about can we use SIM card in a router?

The answer is Yes, but how does a SIM card router work?

4G router is based on the common wireless routing, and improves the function of 4G dialing, which can complete the function of wireless network connection.

The 4G communication module is built into the PCB board, and the data signal of the communication base station is accepted according to the inserted SIM card to connect the network. The external connection is to connect the 4G network adapter to the USB port to complete the dial-up connection, that is, to complete the sharing of resources on and off the network.

Wired router is not convenient to connect to the network cable, complete the whole batch of electronic computers on the external network effect. 4G industrial router is the industrial version of 4G router, which is basically improved. It has high reliability transmission efficiency and can adapt to the extreme outdoor natural environment in high temperature and cold.

4G wireless router is a multi-functional industrial Internet of Things terminal device, which integrates router, gateway, serial port, DIO and other functions. It supports POE power supply, IO input/output, RS232 or RS485 serial port, supports transparent-transmission and Modbus protocol, and is used to extend IO and connect to PLC and other devices. E-Lins also has router models with dual SIM card redundancy design for selection, such as H900, which can ensure stable and reliable data transmission. It supports Modbus TCP protocol and is compatible with most PLC protocols, greatly simplifying the construction cost of field wiring and reducing the cost of operation and maintenance. It is widely used in smart environmental protection, smart water conservancy, smart agriculture, smart mine, smart transportation, smart city, smart manufacturing and other industries.

E-Lins industrial 5g/4g router can apply on many areas like mining, transportation, oil field, smart water conservancy, agriculture, automatic driving, reservoir monitoring, vending, ticket machine and so on.

Let’s take ticket machine for example. Cinemas are usually settled after the completion of the construction of the shopping mall, and all the hardware matching has been completed. The biggest problem in the placement of self-service ticket picking machines in cinemas is the difficulty in network wiring. Different ticket picking machines are different for different movie group-buying companies. Therefore, the cost of network access is high. The overall routing time cycle is also long, so the self-service ticket machine can be directly used with 4G router, easy access, simple construction, no need to apply for property broadband access. At the same time, it is also very convenient to move the location. Unlimited deployment distance, short construction period, low equipment investment cost; The equipment distributed in various regions can be monitored, configured, upgraded, diagnosed, maintained and controlled online through the router management platform.

4g/5g routers, the unobserved devices, actually play a very important role in our life, changing our lives without us even knowing it.
