Yes, all major eSIM providers work well on ATAF buses and the tramvia system. Underground coverage at Santa Maria Novella station is strongest with Wind Tre-partnered providers like Amigo eSIM.
How much data do I need for a week in Florence?
Plan for 3-5GB weekly for typical tourist usage including maps, photos, and social media. Add 2-3GB extra if using translation apps frequently in museums or for extensive restaurant research.
