It's a new modem, so it should work. I had previously purchased what should have been a slightly more modern, better supported modem but lenovo's uefi whitelist suprised me. so i had a choice of two modems that would work with my carrier and band. i bought the cheaper one.

The gobi 3000 didn't normally need any firmware upload since it came with firmware on flash. But newer modems like the MC73xx and MC74xx have a concept of firmware image and operator matching, where they will stay in low-power mode if none of the installed images are usable.
