@effendi: Thanks for your very detailed information on acquiring prepaid SIM and data plans in Italy. I will be going on a one-week cycling tour of Tuscany later this week. I would like to get a prepaid SIM with data for one week. From the information you provided, it appears 3 would have the best plan: The Super Internet plan at 3GB (100MB limit per day) for 5 euro per month. Is there any reason you recommended WIND and TIM over 3?
Super Internet
Thanks!
