We have used a 'Tre' '3' micro sim in our iPads for the last couple of years. Our house is located in a hill-top town in Umbria near Perugia and reception there for everything is pretty lousy but we have had no problems with getting n receiving emails, blogging etc. most of the time Skype is ok too. Down at lake level reception is perfect. We took the PAYG offer. (Ricaricabile) Got it from theTre shop outside Perugia but unless your Italian is good, do translate what you want before you ! The offer for the sim was €25 .(now I think €30 ) which breaks down as €5 for the sim and €25 credited on your phone. 3GB a month for four months. We had to buy four months useage. cant just do one month. Then you top it up either over the Internet of at local shop. If u don't use all of it you can use it once u arrive back in the UK which is good. There is a good Tre website for Italy which I would recommend looking at to see latest offers. Can def. recommend though. over 5 years ago
In Italy there are four main operators: TIM, Vodafone, Wind and 3 (Tre). All of them offer rechargable plans.
In my opinion, if you use it for a short period, all of them are good. In my opinion, the best coverage is with TIM and Vodafone. over 5 years ago
