Compatible USB Cellular Modems

Hello,

I have a Zyxel AX7501-B1 received from my fiber supplier.

I've tried connecting a Huawei e3372h-607 USB modem to it, and the cellular statistics page shows:

Cellular Card Model: 3G Dongle detected

VID/PID: 12d1 / 14dc

However I'm unable to connect to the cell network.

Is this USB model compatible with this router? If not, can you provide a list of compatible modems?

Thanks,
