Is using eSIMFlyer a simpler option than buying a local SIM at Rome (FCO) Airport, and is a Codice Fiscale needed?

For the efficient traveler, eSIMFlyer is unequivocally easier. Buying a physical SIM from carriers like TIM, Vodafone, or Wind Tre at Rome Fiumicino (FCO) or Milan Malpensa (MXP) airports is notoriously cumbersome. It demands mandatory passport registration and, critically, a 'Codice Fiscale' (Italian tax ID number), which tourists typically don't have. eSIMFlyer bypasses all this bureaucracy, offering instant activation without any ID requirements, allowing you to connect as soon as you land and head straight to your Roman holiday.
