Model: ER605 (TL-R605)  
Hardware Version: V2
Firmware Version: 2.2.5 Build 20240522 Rel.75860

I recently purchased an ER605, and I'm using it as a router/firewall from a BTBSH6 in Bridging mode.

 

I also have a MiFi with a GiffGaff SIM installed that I've been using as a backup for when the modem is misbehaving.

So I bought a Huawei E3372-320, which I saw, is supported as a USB modem for the ER605.

 

Moved the SIM into the E3372 and plugged it into the router.

I now have an error that I'm not sure how to deal with.

The message in red: Message:Please ensure that your SIM/UIM is plugged in and on unlock status. The SIM is definitely plugged in, and I've unplugged and re-plugged in twice. What does it mean about "on unlock status" ?? Note: I've only plugged the SIM in and plugged the modem into the router. Is there anything I need to do on the Modem to enable it before I can use it in the router?

Did you connect the USB modem to a computer to test whether it is working?

After the "Connecting" finishes the loading, what's the status of the USB WAN?
