We will have an unlocked phone, but want to buy a SIM card in Venice. We have to contact a person to take us to our apartment before we take the vaporetto. Can we get a card at the aiport (I remember it as being small). What about the square where the buses from the airport let you off? Any help would be appreciated (I am older than the Grand Canal and I am not very tech savvy so I am really grateful for the help.)
