4. You can remove SIM1 to make the router fail to connect to network via it. Go to “Status > Cellular”

again, and you will see the router is connected to the network through SIM2.

Now

SIM2 becomes the main SIM, and SIM1 runs as the backup.

The router won’t reconnect via SIM1 until SIM2 fails.

5.13.2 WAN Failover

WAN failover involves in Ethernet WAN interface and cellular interface. Either can be used as main WAN
interface. If the main interface fails, the router will automatically failover to the backup interface until the
main interface functions properly again.

Application Example

An UR75 router is connected with PC via GE 1 (LAN) port, and GE 0 (WAN) of the UR75 is connected to
Internet via wired network. Configure WAN failover in the router so that it can failover to cellular to get
Internet access in case of the malfunction of wired network and failback to wired network when it’s
available again. Please refer to the topological graph below.
