Yes. Any recent US phone works in Italy. Verizon, AT&T and T-Mobile all roam on Italian networks, so your phone has a signal as soon as you land in Rome or Milan. What changes is the price: Verizon and AT&T charge $12 a day per line, and T-Mobile's included data is a few gigabytes for the whole trip. Ten days in Italy for two people can add $180 to $240 to your phone bill.
If your phone is unlocked, a travel eSIM gives you data for the whole trip at a fixed price, from $11.99 for 7 days or $19.99 for 15 days, while your US number stays on for calls, texts and bank codes.
What each carrier charges in Italy
| Carrier | What you get in Italy | What it costs |
|---|---|---|
| Verizon | TravelPass: your plan's talk, text and data, with 5 GB of high-speed data per 24-hour session, then 3G speeds | $12 a day per line. Unlimited Ultimate includes some international data each month |
| AT&T | International Day Pass: your plan's talk, text and data | $12 a day for the first line, $6 for each extra line, at most 10 days charged per bill period. Unlimited Elite 2.0 includes 20 GB a month |
| T-Mobile | Included roaming on most plans: 5 GB of high-speed data on Experience More, 15 GB on Experience Beyond, then slow data | No extra cost, or a pass for more data. Essentials has no data abroad without a pass |
On Verizon and AT&T the day pass switches itself on: one call, one sent text or one background app sync in Italy starts a day. Our guides explain what triggers it and how to avoid a surprise: Verizon, AT&T and T-Mobile. On Mint, Visible, Cricket, Google Fi and other carriers the rules differ a lot: will my phone work in Europe? links to each.
What a 10-day trip costs
| One phone | Two phones | |
|---|---|---|
| Verizon TravelPass, 10 days | $120 | $240 |
| AT&T International Day Pass, 10 days | $120 | $180 |
| T-Mobile Experience More | Included, 5 GB at full speed in all | Included, 5 GB each |
| Europe eSIM, 15 days, 1.5 GB a day | $19.99 | $39.98 |
T-Mobile's included data is the cheapest if it is enough for you. Five gigabytes covers maps, messages and some photos, but not much streaming or video calls over ten days. In that case the eSIM is about more data at full speed, not about saving money.
Will my phone itself work there?
For data, yes, on any phone from the last eight years or so. Italian networks run 4G and 5G on frequencies US phones support.
For calls, there is one catch. Italian operators have been switching off 3G, so calls travel over 4G (VoLTE), and that has to work with your carrier's Italian partner. On some older phones it does not, and then data works but calls fail. If that happens:
- Use Wi-Fi calling. Calls over Wi-Fi to US numbers are free on Verizon, AT&T and T-Mobile. Turn it on before you leave the US.
- Use WhatsApp, FaceTime or another app. WhatsApp is widely used in Italy, by hotels and tour guides too, so have it ready.
To use a travel eSIM, your phone must be unlocked. Check it in 30 seconds: is my phone unlocked?, and does my phone support eSIM? Our model pages say how a US iPhone 12, iPhone 13, iPhone 14, iPhone 15 or iPhone 16 runs a travel eSIM beside your home line.
Which plan fits an Italy trip
Our Italy page sells the Europe plans: one eSIM for 30 countries, so it keeps working if your trip continues to France, Switzerland or Greece. Going on to France? See will my phone work in France?
- A week in Rome, Florence and Venice: 1.5 GB a day for 7 days, $11.99. Enough for maps, train tickets, messages and photos.
- Two weeks, or a trip with remote work: 1.5 GB a day for 15 days at $19.99, or unlimited for 7 days at $19.99 if you share your connection or take video calls.
- A stopover or one day across a border: a one-day plan at $1.99.
Coverage is strong in cities and along the high-speed rail lines between Rome, Florence, Bologna, Milan and Naples. Tunnels on those lines and remote mountain or coastal roads can drop the signal briefly on any network.
Why mobile data matters on an Italian trip: train tickets and changes live in the Trenitalia and Italo apps, rail strikes are announced at short notice (see our Italy strike calendar), and many museums and sights work with timed online tickets you show on your phone. There is no UberX in Italy: which apps book a car.

Before you fly
- Decide: carrier pass, included roaming, or a travel eSIM for data.
- Turn on Wi-Fi Calling while you are still in the US.
- Install your eSIM at home on Wi-Fi: iPhone or Android. When you land, set it as your data line and turn data roaming off on your US line, so the day pass never starts.
- Pack a plug adapter. Italy uses type L and type C plugs. Phone chargers rated 100 to 240 V need an adapter, not a converter.
- Know the emergency number: 112.
