Since a good working organization depends nowadays from being reachable by phone/mail/messages, I advise you, once you are in Italy, to enter one of the several telephone shops as TIM, Vodafone, Wind etc….and buy a prepaid Sim Card to use during your stay in this country (may be inserting it in an old device), this, to be sure that the communication just before and on arrival can be smoother since no high costs of phone calls from your home country would be heavy on your pocket….
The tariff of a prepaid card are 5β¬ for the activation and a free amount between 10-15-20-25-30β¬ for the phone/messages credit can be added according to your use….
For example: TIM has just come out with a special offer for tourists visiting Italy: 100 minutes and 4GB for 20β¬ !!
