Can I use my US phone in Italy or should I get an eSIM?

Both work; an eSIM is usually cheaper and takes five minutes. Most US carriers offer an international day pass around $10–12 a day, which is fine for a long weekend and expensive over two weeks. An eSIM from a European provider gives you 10–20GB for the trip for a fraction of that, installs before you fly, and keeps your US number active for calls and texts. Check your phone supports eSIM and is carrier-unlocked before buying. Wi-Fi is widespread in hotels and cafés but you'll want data for maps, train apps and translation — the three things you'll use constantly.

This one changes. Last checked August 13, 2026 — confirm it close to your trip.
