Bottom line: The hard part of getting an Italy SIM card is not finding a shop. It is completing the contract. Article 98-undetricies of the Italian electronic communications code requires the operator to identify you before the service is activated and to take a copy of your identity document. For citizens of non-EU countries, the text specifically names a passport or equivalent travel document. On top of that, the budget brands most often sold to visitors carry a contractual speed cap of 30 Mbps that the regulator publishes openly.
If you want data working the moment you land, an eSIM can be installed before you leave home. You can pick a plan sized to your trip from Coral eSIM's Italy plans.
Italian law requires identification before a SIM is handed over
What the article actually says
Article 98-undetricies of legislative decree 259/2003, titled "Identification of users," is the rule that governs every prepaid SIM sold in Italy. In the version in force since 12 April 2025, it requires the following.
- Customers must be identified before activation of the service, at the moment the SIM card is handed over or, in the case of a digital SIM (eSIM), when the profile is supplied
- For a new activation, a number port, or a SIM replacement, the operator must capture the holder's personal details as shown on an identity document, plus the document type and number, and take a copy of it
- Operators must make their lists of prepaid and postpaid mobile customers available to the data processing centre of the Ministry of the Interior
This is why an Italy SIM card is not sold the way a transit pass or a snack is sold. Purchase, identification, and activation are one procedure, and the shop is not being cautious when it asks for your document. It is meeting a legal obligation.
Non-EU travellers are named explicitly
The same article contains a clause added specifically for non-EU nationals. Where the customer is a citizen of a state outside the European Union, the operator acquires a copy of the residence permit, or of the passport or equivalent travel document, or of a valid identity document.
If you are travelling on a US, UK, Japanese, Chinese, Australian, or any other non-EU passport, that clause is about you. It is not a "bring ID just in case" situation. Without the physical document in your hand, the transaction cannot be completed, so leaving your passport in the hotel safe means a second trip.
The requirement dates back to 2005
This is not a recent tightening. Article 6 of decree-law 144/2005, an emergency counter-terrorism measure that took effect on 28 July 2005, amended what was then article 55(7) of the code. It replaced "at the moment of activation of the service" with "before activation of the service, at the moment of delivery or provision of the necessary electronic card (S.I.M.)," and added the requirement to obtain a reproduction of the document presented. Two decades on, the process is routine for Italian retailers, but it still takes time at the counter.
If you would rather not spend that time on arrival day, you can load a profile onto your phone before departure. Coral eSIM's Italy plans are set up at home, and our travel eSIM setup guide walks through the steps.
Why vending machines and online sign-up still exist
The same article that imposes the obligation also relaxes how it is met. It states that identification of the contract holder may also be carried out remotely or indirectly, provided the data needed to recognise the user is correctly captured and data protection rules are respected.
That clause is the legal basis for self-service kiosks and online activation in Italy. Decree-law 144/2005 goes further for data-only SIMs, allowing indirect identification through SMS-based recognition and registered payment cards.
The important reading is the opposite of what travellers usually assume: an unattended or online purchase does not skip identification. It moves the document check from a counter to a screen. The only carve-out in the article is for internet-of-things SIMs that are permanently installed inside connected objects and cannot make calls, send SMS, or connect to the internet if removed.
The codice fiscale problem
A second obstacle rarely covered in English guides is the codice fiscale, Italy's 16-character tax identification code. It is used to identify foreign nationals in dealings with Italian public authorities, and some contract forms and systems are built around it.
Getting one is the problem. According to the Italian Revenue Agency, foreign citizens applying for a first codice fiscale must book an in-person appointment at an office. Italian consulates abroad, immigration one-stop desks, and police headquarters can also issue it. None of those is something a tourist can arrange on the afternoon they land. If your plan depends on a local SIM, decide in advance what you will do if the number is requested.
The brand you buy decides your maximum speed
The regulator publishes the contractual caps
Italy publishes something most countries do not. Under resolution 23/23/CONS, AGCOM, the communications authority, lists every virtual operator and major sub-brand together with its host network, the generations it uses, and any contractual speed cap. The brands most often recommended to visitors look like this. The table is updated every six months; the figures below are as published on 13 August 2026.
| Brand | Host network | Generations | Contractual cap |
|---|---|---|---|
| ho.mobile | Vodafone Italia | 2G-4G | 30 Mbps |
| Kena | TIM (brand sold by TIM) | 2G-4G | 30 Mbps |
| VERY MOBILE | Wind Tre (brand sold by Wind Tre) | 2G-3G-4G | 30 Mbps |
| Lycamobile | Vodafone Italia | 2G-4G | 60 Mbps |
| Digi Mobile | TIM | 2G-4G | 100 down / 50 up Mbps |
| Fastweb | Vodafone Italia | 2G-4G-4.5G-5G | None |
| PostePay | TIM | 2G-4G-5G | None |
"It runs on a major network" is not an argument
The decisive detail is a footnote AGCOM adds itself: Kena is not a virtual operator but a brand marketed by TIM, and VERY MOBILE is not a virtual operator but a brand marketed by Wind Tre. In other words, a cap of 30 Mbps applies even when the seller is the network owner.
So "it uses the TIM network, it must be fast" does not survive contact with the table. The column that matters is the cap, not the brand and not the host. The same table also shows that most capped brands list no 5G at all.
The 331 Mbps figure is measured on a different set of operators
AGCOM runs annual drive tests in 45 cities. The 2025 campaign, carried out between September and December and published on 23 February 2026, averaged about 331 Mbps down in stationary tests and about 269 Mbps down in urban mobile tests. Italy is not a slow country by these numbers.
But the measurement covers only the five operators with their own infrastructure reaching over 50% population coverage: Fastweb, Iliad, TIM, Vodafone, and Wind Tre. Nobody on a 30 Mbps capped brand experiences that 331 Mbps.

When a local SIM makes sense, and when it does not
An Italian SIM works across the EU
The strongest practical case for a local SIM is a multi-country itinerary. Per the European Commission, within the EU plus Iceland, Liechtenstein, Norway, Moldova, and Ukraine, you pay domestic rates with no roaming surcharge. A SIM bought in Rome works in France or Spain on the same terms.
The limits are published too. Under the fair use policy, the data surcharge ceiling is EUR 1.30 per GB plus VAT in 2025, falling to EUR 1 plus VAT from 2027, and a surcharge can apply if, over a four-month observation window, your use abroad exceeds your use at home. A few weeks of travel is not the scenario those rules target, but a long stay is worth checking.
Short trips rarely justify the paperwork
Stack up the identification step, shop opening hours, the language barrier, and the possibility of being asked for a codice fiscale, and the case for a local SIM on a short trip weakens quickly. You need connectivity most on the first day, for transport and check-in, which is exactly when you would be queuing to obtain it.
A reasonable order of decision looks like this.
- Several weeks or more, based in Italy — the paperwork amortises, and a local SIM is sensible
- Multiple EU countries but a short stay — a travel eSIM valid across the region involves less process
- A week or less — choose something you can finish setting up before departure
- You need calls or SMS on a number — settle the number question first (eSIMs and phone numbers, receiving SMS verification codes)
For the alternatives, see roaming versus eSIM and airport SIM versus eSIM.
Rome's own airport operator sells a travel eSIM
A telling detail: Aeroporti di Roma, the company that runs Fiumicino and Ciampino, sells a travel eSIM on its official site. It can be bought online, through the app, or from touchpoints inside the airport including ADR's digital totems. The service itself is provided, sold, and operated by BNESIM Limited.
Its own description says that for travellers arriving in Rome from outside Europe, an Italy eSIM can be a practical way to get online during the stay "without immediately looking for a phone shop." The organisation that leases the retail space in the terminal is pointing arrivals at something other than a physical local SIM.
If you go that route, check the device side first: eSIM device compatibility and whether your phone is carrier-unlocked. If nothing connects after landing, work through eSIM not working on arrival and APN settings.
FAQ
Do I need a passport to buy a SIM card in Italy?
Yes. Article 98-undetricies of the Italian electronic communications code states that where the customer is a citizen of a non-EU state, the operator acquires a copy of the residence permit, passport, equivalent travel document, or valid identity document. The same article requires a copy of the identity document for every new activation, number port, and SIM replacement, regardless of nationality.
Can I buy an Italian SIM card as soon as I land?
Do not assume so. Retail availability and opening hours vary by airport, terminal, and time of day, and because the purchase is bound to an identification procedure, it is not a pay-at-the-till transaction. Aeroporti di Roma, which operates Fiumicino, points arrivals from outside Europe toward a travel eSIM as a way to get connected without immediately looking for a phone shop.
Do I need a codice fiscale to get an Italy SIM card?
The law requires identification by document, not the tax code as such, but some contract forms are built around it. The Italian Revenue Agency states that foreign citizens applying for their first codice fiscale must book an in-person appointment at an office; consulates, immigration one-stop desks, and police headquarters can also issue one. None of these is realistic to arrange on your arrival day.
Why is my cheap Italian SIM card slow?
Because it may carry a contractual speed cap. AGCOM's published table lists ho.mobile, Kena, and VERY MOBILE at a maximum of 30 Mbps. The regulator's own footnotes state that Kena is a brand marketed by TIM and VERY MOBILE a brand marketed by Wind Tre, so running on a major network says nothing about the cap. The table is refreshed every six months, so check the current entry before buying.
Does an Italian SIM card work in other EU countries?
Yes. Per the European Commission, domestic rates apply with no surcharge across the EU plus Iceland, Liechtenstein, Norway, Moldova, and Ukraine. Under the fair use policy the data surcharge ceiling is EUR 1.30 per GB plus VAT in 2025 and EUR 1 plus VAT from 2027, and a surcharge may apply if usage abroad exceeds usage at home over a four-month observation period.
Choose an Italy SIM card by whether you can complete the contract, not by price
Almost everything written about Italy SIM cards is about which plan is cheapest and where the shops are. Read the primary sources and a different picture emerges: what actually constrains travellers is a legal identification procedure that has been in force since 2005, and a set of contractual speed caps the regulator republishes every six months. Neither is explained at the counter.
So the first question is not price. It is whether the length of your stay justifies the procedure. If you are in Italy for several weeks, a local SIM is a rational choice. If you are there for a week and need maps and booking confirmations working the minute you land, something you can finish configuring at home fits better. Coral eSIM's Italy plans install before departure and connect on arrival, and the full plan list covers other destinations on the same trip.
