Checking phone compatibility
Most iPhones from the XS/XR generation onward, recent Pixel models, and flagship Samsung and Android phones from about 2019 onward support eSIM, though some regional variants are locked to physical SIMs only. Check under cellular or network settings for an 'Add eSIM' option, and confirm the phone is carrier-unlocked before buying any plan.
How eSIM activation works
Providers send a QR code by email after purchase. Scanning it installs the data profile, which can stay inactive until arrival in Italy. On landing, travelers switch on the Italian data line while keeping their home SIM active for calls and texts, avoiding the need to swap physical SIM cards at all.
Comparing providers and plans
Several companies, including Airalo, Holafly, Saily and Nomad, sell Italy-specific or Europe-wide data packages running on major Italian networks. Plans vary by data allowance, validity period, and whether hotspot tethering is included or capped, so it is worth comparing a few before choosing one for a specific trip length.

Estimating how much data to buy
A typical week in Rome using maps, messaging apps and occasional browsing generally falls in a modest data range, with heavier use such as video calls or streaming requiring noticeably more. Buying slightly above an initial estimate avoids running out mid-trip, since add-on purchases are usually straightforward if needed.
