Buying a SIM card at Rome Fiumicino (FCO)

First, work out whether you need to buy anything

Fiumicino is Italy's main international gateway, and a large share of the people walking through arrivals are carrying a phone plan issued somewhere else in the EU or EEA. If that is you, roam-like-at-home already covers Italy at your domestic rates and allowance. The correct purchase is nothing at all.

That is not a hedge — it is the single most useful sentence on this page, and it removes the rest of it for a lot of readers. If your plan comes from outside the EU or EEA, keep going.

The queue is the story at FCO

We hold two figures for the SIM counters in Fiumicino arrivals: 20 minutes at peak and 8 minutes off-peak. Those are the worst numbers of any Italian airport in our data, and they are a direct consequence of FCO's arrival banks — long-haul aircraft landing within the same hour, all of them full.

What is on sale is Vodafone Italy, plus Lycamobile and Iliad through kiosks. We do not hold which arrivals hall each of those sits in, nor their opening hours, so we cannot tell you what is open for a late landing. Do not treat 8 minutes as the number to plan around; it is the figure for a quiet hall, and a quiet hall at Fiumicino is luck.

The passport rule is why the queue moves slowly

Italy requires ID for prepaid SIM registration. Your passport is handed across, copied and typed into a system before the SIM works — every carrier, every seller, no exceptions.

That is what turns a purchase into a transaction of several minutes, and it is why the queue ahead of you moves at the pace it does. Twenty people in the line is not twenty people buying a bottle of water.

It also multiplies. A family of four is four registrations at one window, which is a materially different proposition from four phones set up on the sofa at home the night before.

What it costs, and what the same money buys online

Our figure for a local SIM bought at an Italian airport is about $18. Here is what the eSIM market charges for Italy. Airalo and Saily rows were read from the providers' own sites on 13 August 2026.

Read to the bottom of that table. The 50 GB month at $35 works out at $0.70 a gigabyte, which makes Italy one of the better-value markets on this site — the big plan is the cheap one, and it is the row most people never scroll to. Even the 10 GB month costs roughly what the counter wants for a tourist SIM, and it is working before you reach passport control.

"Mamma Mia" is Airalo's retail name for its Italian product, not a network. Airalo does not publish which Italian operator its plans roam onto, and neither do Saily, Nomad or Holafly — the operators this page once listed against Holafly's plans came from our own data rather than from Holafly. eSIM Go sells nothing to consumers and names no network anywhere. eSIMCard does publish host carriers on its country pages, confirmed on its Japanese one, but we have not read its Italian page and hold no network for it here. So do not choose on network grounds at all.

The Leonardo Express, and the verdict

The train from Fiumicino to Roma Termini is the part of the journey where you actually want data: platform, onward metro, the address of wherever you are staying. Queue 20 minutes first and you get connected roughly when you stop needing it.

So the verdict for FCO is unusually clear. EU and EEA arrivals: buy nothing. Everyone else with an eSIM-capable phone: install before you fly, because this is the Italian airport where the queue genuinely costs you time. The counter is worth it only if your handset cannot take an eSIM, or you need an Italian number for calls — and in that case, off-peak, eight minutes is survivable.
