A wireless dual sim 4g router is a device that performs the functions of a router with 4g external antenna but also includes the functions of a wireless access point and a network switch. They are commonly used to allow access to the Internet or a computer network without the need for a cabled connection. It can function in a wired LAN (local area network), a wireless only LAN (WLAN), or a mixed wired/wireless network. 

4g router dynamic routing allows as many routes as possible to remain valid in response to the change.

Systems that do not implement dynamic routing are described as using static routing, where routes through a network are described by fixed paths. A change, such as the loss of a node, or loss of a connection between nodes, is not compensated for. This means that anything that wishes to take an affected path will either have to wait for the failure to be repaired before restarting its journey, or will have to fail to reach its destination and give up the journey.

Dynamic routing is a networking technique that provides optimal data routing. Unlike static routing, dynamic routing enables routers to select paths according to real-time logical network layout changes. In dynamic routing, the routing protocol operating on the router is responsible for the creation, maintenance and updating of the dynamic routing table. In static routing, all these jobs are manually done by the system administrator.

Dual sim 4g router still can be regarded as a transponder that forwards the broadband network signal from the wall in the home to the nearby wireless network device through the antenna. The general wireless router with 4g external antenna signal range is 50 meters in radius, and now some wireless routers have a signal range of 300 meters.

Wireless dual sim 4g routers are widely used in today's applications and cover almost all areas. Leading people's lives are increasingly inseparable from the wireless network.
