What options are there for visitors to Italy in getting a sim card with a large amount of data (3G or 4G) or alternatively a portable wifi hotspot that I can pick up and drop off easily.
I will be travelling all over Italy, including Venice, Florence, Tuscany, Pisa, Cinque Terre, Rome, Naples.
Ideally this should work in the cities and in the country side (I will be travelling by train and would like to use it on the long journeys)
Edit: This question and answers answers the sim card part of the question, but since I only need internet data, I have changed my question to ask only for portable wifi hotspots.
And I will be travelling for about 2 weeks. I'm looking for "a lot" of data (1GB+ per day).
