Italy is one of the most visited countries in the world, and for travellers with an EU SIM the basic answer is easy: Italy is covered by Roam Like at Home, so your plan works much as it does at home. Visitors from the United States, the United Kingdom, Australia or Asia usually face daily roaming charges, and an Italian trip leans on data more than most: train tickets, museum time slots, restaurant bookings and maps through medieval streets.
Italy also has a few places where the phone quietly leaves EU rules, and a train line where it loses the signal for long stretches.
Key facts for Italy
- EU roaming: covered by Roam Like at Home
- Local networks: TIM, Vodafone, WindTre, Iliad (depending on the plan)
- Emergency numbers: 112; the older numbers 113 (police), 115 (fire) and 118 (medical) also work
- Embassies: in Rome, with consulates in Milan and other large cities
Where Italy's roaming has gaps
San Marino sits inside Italy but is not part of the EU, so EU roaming rules do not cover its own network. Check your tariff before a day trip from Rimini. In the north, around Lake Como, Lake Maggiore and the valleys near Lugano, phones can pick up a Swiss network, which EU plans may charge for. Choosing an Italian network manually avoids it.
Ferries to Sardinia, Sicily, Corsica, Greece and Croatia are a separate case: out at sea, phones may switch to the ship's own network, which is billed separately from EU roaming. Turning off data roaming on board is the safest choice.
Trains, tunnels and timetables
Italy's high-speed trains, run by Trenitalia and Italo, sell tickets and show changes in their apps, so a working connection at the station matters. Between Bologna and Florence the high-speed line runs mostly through tunnels, and the signal comes and goes for much of the journey. Download tickets and boarding details before you board.
Cities, coast and mountains
Rome, Milan, Florence, Venice and Naples have strong coverage. In many historic centres, driving is restricted inside limited-traffic zones (ZTL) watched by cameras, so check your route before driving into a town centre. Coverage thins on mountain roads in the Dolomites, on some coastal paths such as those of the Cinque Terre, and in rural parts of Sardinia and Sicily; offline maps help there.
Getting connected
Travelling with an EU SIM? Nothing changes on the mainland, Sicily or Sardinia. A travel eSIM is useful if your tariff gives you only a small data allowance abroad, or if your route touches San Marino or Switzerland.
Travelling with a SIM from outside the EU? Install a travel eSIM before you fly. It activates its validity on the first connection in Italy, keeps your own number reachable for texts, and lets WhatsApp, maps and train apps run on its data.
Italian prepaid SIMs are sold in operator shops and require ID and an Italian tax code, which shops usually generate for visitors.
Consular protection: who to call in Italy
- 112 is the European emergency number and works across Italy.
- 113 reaches the police, 115 the fire service and 118 medical emergencies.
- Embassies are in Rome and many countries have consulates in Milan and other large cities. The Telcomia app shows yours, with address and phone.
- Emergency phrases in Italian are ready to show on screen in the app.
Questions travellers ask about Italy
Does my EU phone plan work in Italy?
Yes. Italy is covered by Roam Like at Home, within your tariff's terms. San Marino and Swiss networks near the border are exceptions.
Why do I lose signal on the train to Florence?
The high-speed line between Bologna and Florence runs mostly through tunnels. Download tickets and maps before boarding.
Which networks does a Telcomia eSIM use in Italy?
TIM, Vodafone, WindTre or Iliad, depending on the plan, with 4G and 5G where available.
Will my phone work on the ferry to Sardinia?
Near the coast it uses land networks. Further out it may switch to the ship's network, which is billed separately.
The short version
From the EU, your plan covers Italy, but watch San Marino, the Swiss lakes and ferries. From outside the EU, install a travel eSIM before you fly and download your train tickets before boarding.
