Go to Italy in mid-June for about five or six days. Is it better to buy a local calling card or rent a mobile wifi?

Depends on how you want to use it. If you go alone and don't like surfing the Internet, you can buy a phone card. If there are a group of people who like surfing the Internet, renting mobile WIFI is definitely a lot of cost-effective. Mobile WIFI with unlimited traffic is easy to carry and can surf the Internet anytime and anywhere. Very good. Please search Caifu on Taobao for reference ~ ~
