Thanks for the answer. I just have the UMTS Module. I got an other question about the GPS. I start AirCard Watcher an click on GPS button to show the GPS monitor. It's says 'Ready' but it shows 0 satellites acquired all the time. I press 'Start', maybe it will acquire satellites then. But no, it says 'Session start, waiting for the patch' (translate from french). And I never get my position. So how this GPS works! Thanks
