Italy eSIM

Italy is easy to stay online in as long as you sort data before you land: Italian tourist SIMs come from shops, need your passport and a tax code, and won't work in your phone until the paperwork is done. If your SIM is from an EU country, it already roams like at home here; this page is for visitors from the UK, the US, Canada, Australia and beyond.

What a week of data costs in Italy

Prices for 7 days of data, checked on 2 November 2026. Daily passes charge for each day you use the phone abroad, per phone.

For a family of four on Verizon, that's $336 for one week. O2 and T-Mobile customers may need nothing extra for a short trip, though 256 kbps is slow for maps and photos.

If your SIM is from the EU, you roam like at home in Italy, as long as you spend more time at home than abroad. The UK isn't part of those rules, which is why the UK prices above vary by network.

Landing at Rome Fiumicino (FCO), Milan Malpensa (MXP), Venice (VCE), Naples or Florence

Switch the kimsim line on as the plane taxis to the gate and turn on Data Roaming for that line only. Then walk through passport control, collect your bags and go through customs. With the eSIM already working, you can walk past the phone shops in arrivals.

Entry rules. Italy is in Schengen. Since 12 October 2025, the EU's Entry/Exit System records non-EU visitors' fingerprints and a photo at the border, and it has been fully in place since 10 April 2026. ETIAS, the €20 travel authorisation for visa-free visitors, is not in operation yet, so don't pay any website that offers one today.

Into the city:

• Rome Fiumicino: the Leonardo Express runs non-stop to Roma Termini in 32 minutes, every 15 minutes, for €14.
• Milan Malpensa: the Malpensa Express reaches Milano Cadorna in about 38 minutes and Milano Centrale in about 51.
• Venice Marco Polo: the ATVO express bus takes about 20 minutes to Piazzale Roma, where the water buses start.
• Naples: the Alibus takes about 15 minutes to the central station and 35 to the port for the Capri and Amalfi ferries. From 1 November 2026 it runs only 06:00–09:00 and 15:00–18:00, so check before you land.
• Florence: the T2 tram stops two minutes' walk from arrivals and runs to Unità, by the main station.

Venice day trips. On busy spring and summer days, Venice charges day-trippers an access fee, paid online for a QR code that staff check at entry points. Overnight guests are exempt but still register for a code. Keep the QR code saved on your phone, not just in an email.

Networks and coverage

Italy has four mobile networks: TIM, WindTre, Fastweb + Vodafone and Iliad. WindTre is the 2016 merger of Wind and 3 Italia. Iliad launched in Italy in May 2018. Swisscom bought Vodafone Italia on 31 December 2024 and merged it into Fastweb on 1 January 2026; the Vodafone name stays in use under licence.

Your phone shows the Italian operator's name, not kimsim. This plan uses TIM, WindTre (listed as Wind) and Iliad.

Coverage is generally strong in cities, along the motorways and on the high-speed rail lines. Expect it to thin in Alpine and Dolomite valleys, on the Amalfi Coast road's cliffs and tunnels, in the Cinque Terre's rail tunnels, and in the hill country of Sardinia and inland Sicily. Near the Swiss, French, Austrian and Slovenian borders, your phone can latch onto the neighbour's network; if it does, choose an Italian network by hand.

The networks your plan uses are listed above.

Region by region

• Rome: dense and well covered. Signal can fade deep inside churches, catacombs and the Vatican Museums. The Vatican sits inside Rome and our Vatican City plan lists the same Italian networks, so a visit to St Peter's usually keeps you on one of them.
• Florence and Tuscany: fine in Florence, Siena, Pisa and Lucca. On country roads through Chianti and the Val d'Orcia, signal can drop between villages, so download an offline map.
• Venice: good across the city. Narrow alleys and thick walls can weaken signal indoors.
• Amalfi Coast and Capri: fine in Amalfi, Positano and on Capri. The coast road winds through tunnels and under cliffs, so expect short gaps on buses and in cars.
• Cinque Terre: fine in the five villages. The train between them spends much of its time in tunnels, so save tickets and maps before you board.
• Dolomites and the Alps: good in Cortina, Ortisei and the valley towns. High passes, hiking trails and cable-car tops can go quiet.
• Sicily and Sardinia: good in Palermo, Catania, Taormina, Cagliari and the resort coasts; patchier inland.
• San Marino: a separate country with its own operator, Telecom Italia San Marino. If you're staying there, add a San Marino eSIM.

This is general guidance, not a coverage map.

Trains, ferries and buses

High-speed trains are the easy way between the big cities. Trenitalia's Frecciarossa runs Rome to Milan in as little as 2 hours 50 minutes and Rome to Florence in just over 1.5 hours. Italo runs Rome to Naples in about an hour. Signal can drop in tunnels on the high-speed lines, so download tickets first.

Regional trains cover everything else. Paper regional tickets must be stamped before you board. The Cinque Terre Express between La Spezia and Levanto ran every 20–30 minutes from 14 March to 1 November 2026; in winter, ordinary regional trains run less often.

Ferries to Capri, along the Amalfi Coast and across to Sicily stay close to land, so data usually keeps working. Longer crossings to Sardinia move onto the ship's satellite network, which isn't covered by EU price caps. Keep roaming off on your home line on board.

Apps worth having

• Uber in Italy books licensed taxis through itTaxi, plus Uber Black and other premium cars. There's no UberX-style cheap ride. Uber Taxi is listed in cities including Rome, Milan, Naples, Florence, Palermo and Cagliari.
• itTaxi is the app of Italy's radio-taxi cooperatives. FREENOW books taxis in Rome, Milan, Naples and Turin. Set accounts up at home, because sign-up can send a code by text to your usual number.
• Trenitalia and Italo apps hold your train tickets and show platform changes. Save tickets offline in case of tunnels.
• WhatsApp is how many B&Bs, drivers and restaurants message you. Keep your WhatsApp number working abroad.
• Maps: download offline areas for the Dolomites, Tuscany, the Amalfi Coast and Sardinia.

SIM and phone rules

Italian law makes operators identify everyone who takes a new SIM and keep a copy of their ID. For non-EU citizens, that's a residence permit or a passport. Shops also register the line against an Italian tax code, the codice fiscale. It's built from your name, date and place of birth, and TIM's tourist offer is for customers with a foreign-born code. In practice, the shop works it out from your passport, which takes time at the counter.

A travel eSIM installed at home skips the shop, the passport copy and the tax code. It's data only, so your home number stays in the phone for calls and texts.

Common mistakes

• Leaving Data Roaming on for your home line. That's where daily charges start for UK, US, Canadian and Australian SIMs. Roaming goes on for the kimsim line only. Why roaming goes on for the kimsim line only
• Starting the plan on a stop-over. If you change planes in another country, keep the kimsim line off until you land in Italy. If your plan started early
• Crossing into Switzerland on an Italy plan. Lugano and St Moritz are a short trip from the lakes but outside the plan. How regional plans work, or see the Europe eSIM.
• Trying to install after you land. You need internet to install, and airport Wi-Fi isn't always quick. Install on Wi-Fi before you fly
• No way to call for help. 112 is the emergency number in Italy, but a data-only eSIM can't dial it. Use your home line or any local phone.

How we put this page together

We checked carriers' roaming price pages, TIM's offer documents, Italian law on SIM identification, airport and rail operators' pages, EU sites and the other sources noted above on 1–2 November 2026. TIM's, AT&T's and T-Mobile's pages block automated checks, so we read those prices from the pages' search listings and TIM's own offer sheet. We haven't measured speeds or coverage in Italy ourselves, so coverage notes are general guidance, not a map. kimsim sells the eSIMs on this page.
