This crap has got to stop. It's an external modem, and it does not actually require a Windows program to use. I know, PPTP means you can tell people 'One computer per modem, sorry.' and have them believe you, but no one with half a clue believes it.
Dell, if your Ubuntu install isn't pre-loaded with a pretty PPTP GUI, fix that now and teach your techs to recognize typical Verizon shenanigans.
