Hi, Has anyone managed to use a Three sim in a Dell XPS laptop? My XPS has an internal modem so I just need a sim-only package to get connected. The Three website says the sim must be used in a Three dongle but I wonder whether this is actually locked. Anyone tried it? http://threestore.three.co.uk/dealsummary.aspx?offercode=1MB5GD002 Many thanks, Andy.
