I found some websites saying that you don't have to use Smartview to connect with USB Modem. All you need is to download and install the modem and USB drivers from some website (depends on carrier) and then have it dial some special number (connection as dial-up).
I can't give you any more details since I don't use it, but have you tried contacting Sprint for help, and explaining in detail what you are doing?
Sorry I can't help more.
