AVOID BUYING ANY SIM PLANS IN ITALY, JUST PAY PREPAID CARD INTERNATIONALS OR SO.
Avoid buying any plans or sim card from this operator.
Once you charge they debit always more money for things you don't activate, then accuse you that you are activating this and that game, this and that bla-bla-bla... full of lies! Then you need to recall them and ask them to deactivate, and depends on the moody blues of the operator, they can refund you the money, if operator is nasty, they won't refund anything and you'll need to charge agian.
Unfortunately in Italy there isn't a good solid operator so far. They're all rip off. IF you should come to Italy, try setting up soon a home network if you were to live, otherwise buy just a simple prepaid card to survive from your homecountry, which gives you roaming free within EU, or at least few gigabyte to survive within EU. Or at best cases, just use it from wi-fi free public points, hostels, hotels, bars ect... believe me it will cost you much less to spend for coffees then to pay their fees.
