Setup topology
This is the most basic scenario in which the SIM Injector is connected directly to the cellular router’s LAN
port via an ethernet cable. This allows for the cellular router to be positioned for the best possible signal.
Meanwhile, the SIM cards can be conveniently located in other locations such as the office, passenger
area, or the bridge of a ship. The SIM Injector allows for easily swapping SIM cards without needing to
access a cellular router.
IMPORTANT: Cellular WAN will not fallback to the local SIM if it is configured to use the SIM Injector.
Configuring the SIM Injector
1. Connect the SIM Injector to the LAN port of the cellular router.
2. Insert SIM cards into the SIM Injector. The SIM cards will be automatically detected.
IMPORTANT: SIM cards inserted into SIM Injector must not have a PIN code.
Note 1: The SIM Injector gets its IP address via DHCP and doesn't have a static IP address. To find it’s
address, please check the DHCP lease on the cellular router.
Configuring the Cellular Router
Step 1. Enable the SIM Injector communication protocol.
1a. If you are using a Balance cellular router, go to the Network tab (top navigation bar).
1b. If you are using a MAX cellular router, go to the Advanced tab (top navigation bar).
