We are travelling to Italy with an unlocked gsm cell phone and had planned to purchase a prepaid Italian sim card upon arrival...I have recently read some information that indicates that this is not all tthat convenient. I have read that passport details are a requirement and then it takes 72 hours to activate the card in oreder to use the phone, I have also read that only Italian residents can bur sim cards! This sounds ridiculous...has anybody been ther recently and purchased a card??? pleas advise!!!
