In general, navigation is fast and you can see your usage in real-time in the Cost Manager on the website. The first time you get online you have to register the sim, and then wait for 2-3 mins to get the sim activated. Then you can surf the web as you do with any internet key.
For Skype, which version should I try? PC or Android?
@mingelli: yes, in province of Milan.
