Your router has WiFi and two (2) SIM card ports. This allows you to connect to WiFi at your event, and use cellular as a failover mechanism. If you have two SIM cards in your router, then if one SIM card fails the other SIM card will be activated. For more details on the S700 router visit this page.
First, obtain your SIM cards and install them into your router.
Connect your WiFi and cellular antennas to the back of the device. Note, the paddles are for cellular and go on the outside connectors of the router. The circular antennas are for WiFi and go on the inside connectors. See the diagram below.
Plug an ethernet cable into the port that says “WAN” underneath it. This should be plugged directly into the event WAN (event internet); however, if you are using a multi-port router you can connect this directly to any port on your router. You can use the Additional Ethernet Port to connect any other devices such as a laptop as needed.
