Any SIM card with a 4G data plan will work.

You can connect to the RUT241 over WiFi, with an ethernet cable to a computer, or via rms.tyconsystems.com.

The RUT241 shows the signal strength in the user interface or at rms.tyconsystems.com.

The default IP address is 192.168.1.1

The username is 'admin'. Each RUT241 has a unique password which is printed on the bottom of the unit.

This means the SIM card is not detected. Check the SIM card placement and make sure the contacts are clean.
