How do I use Command line Windows 7 WWAN?

I have an old Compaq C302 laptop that has an Intel processor, 512 MB RAM, 80 GB HDD and running on Windows 7. I recently purchased a plug and play WWAN USB card to access the internet while on the go. I plug it in but my laptop won't detect it. How do I use command line Windows 7 WWAN?
