Looks like that may use a standard HSPA modem to connect, in which case it may be supported directly in Windows without needing to fiddle with the software from the broadband provider. Try disconnecting with the software app, then go to the Windows connections icon in the tray and check out the options. It should show up under the "Dial up and 3G" section, and there should be any number of ways to configure the device, including auto-reconnect options.
