Is this what you have?

If so, then it's a modem + router.

Modems, per se, don't do routing (routers do routing), and hence can't do
NAT.

Secondly, a USB modem would be connected directly to your computer, whereas
the whole point of NAT is to allow multiple computers to be connected to the
device (hence NAT devices, which are usually routers, have ethernet
connections, or someway of connecting an ethernet hub/switch)
