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!
