How much eSIM data for 30 days in Italy?
For 30 days in Italy with normal daily use, TripUtils estimates 12–18 GB. A 20 GB plan is the usual buffer. Not a live price. City maps and messaging fit the normal GB band. An extra eSIM is mainly useful if your home plan has no EU roaming, a tight cap, or you want a local number-free data line.

What to do next
If your home SIM is an EU/EEA plan, Italy is often already included. Check roaming first. If you still want a travel eSIM, pick a Saily plan at or above 20 GB for Italy.

Common questions
Is 20 GB enough for 30 days in Italy?
City maps and messaging fit the normal GB band. An extra eSIM is mainly useful if your home plan has no EU roaming, a tight cap, or you want a local number-free data line. The 12–18 GB estimate plus buffer lands on 20 GB. Hotel Wi‑Fi is not counted. Streaming video on mobile is the usual reason to go larger.
Should I roam in Italy instead?
If your home SIM is an EU/EEA plan, Italy is often already included. Austrian A1, Magenta and 3 day-passes matter mainly outside that allowance or for UK SIMs — type the fee you were quoted.
Do you show live Saily prices?
No. Live prices belong on the provider site. The numbers on this page are a data-size estimate only.
