hi, hope this isn't too off topic: i'm going to Italy next week and would love to hear recommendations on carriers and places to buy an inexpensive nanonsim for my iPhone 5 (unlocked) for both voice calls and data. is it hard to make this purchase with minimal (or no) Italian skills. any recommended shops that would be easier for someone with only a phrasebook/app to assist? i'll be there a couple weeks and have modest needs. (at home, i use about 600mb per month, so i don't need a huge plan and i'm guessing anything over 200mb of data would be more than sufficient) thanks in advance.
