Does the eSIM also work in Hawaii and Alaska?

Hawaii is covered by the T-Mobile and AT&T networks with good 4G/LTE signal on the main islands such as Oahu, Maui and Kauai. In Alaska coverage is more variable: cities like Anchorage and Juneau are well served, but in wild and remote areas the signal may be weak or absent. For both destinations, we recommend downloading offline maps before venturing outside inhabited areas.

Does the signal also reach American national parks like Yellowstone or the Grand Canyon?

It depends on the specific area. At visitor centres and along the main entrances of parks like the Grand Canyon and Yosemite, 4G signal is generally available. In more remote areas of Yellowstone, Death Valley or the canyons of Utah, coverage can be very limited. It is always advisable to download the park's maps offline before entering and to find out where signal is available.

Do I need an adapter to charge my phone in the United States?

Yes. The United States uses Type A and B sockets with a 120V voltage, different from the 230V in Italy. Most modern smartphone chargers support voltages from 100 to 240V (check the label on your power adapter), but you will need a physical adapter for the shape of the plugs, which is flat with two or three blades — incompatible with round Italian plugs.

Can I use the eSIM on domestic flights between American states?

During the flight your phone will be in flight mode, as always. However, many American airlines such as Delta, United and Southwest offer on-board Wi-Fi. Once you land at your destination — whether it is Miami, Las Vegas or Seattle — the eSIM connects automatically to the local network without you having to do anything, which is particularly convenient when travelling between different time zones.

How big is the time difference between Rome and the United States?

The time difference varies depending on the coast: New York and the East Coast are 6 hours behind Rome in summer and 7 hours in winter. Chicago and the Midwest are 7 to 8 hours behind. Los Angeles and the West Coast are 9 hours behind Rome in summer and 10 in winter. This means that when it is 12:00 in Rome, it is 6:00 in the morning in New York and still the middle of the night in Los Angeles — keep this in mind for calls home.

How much does an eSIM for the United States cost?

eSIM plans for the United States start from €1.79. You pay once for the amount of data you choose — no subscription, no monthly fees and no hidden roaming charges. Plans with more data or longer validity cost more.

Is an eSIM or roaming better in the United States?

A local eSIM in the United States is almost always much cheaper than the roaming of your Italian operator. In the European Union roaming is often already included ("Roam Like at Home"), but outside the EU the costs can be very high — with an eSIM you know the price in advance and pay only for the data plan you need.

Which operator or network does the eSIM use in the United States?

The eSIM in the United States connects automatically to local networks such as T-Mobile, AT&T, Verizon — on 4G/LTE and, where available, 5G. Coverage reaches about 93% in inhabited areas. Your phone picks the best available network by itself.

Can I keep my Italian number with the eSIM in the United States?

Yes. Your Italian SIM and number stay active — the travel eSIM works alongside it as a data-only line. You stay reachable on WhatsApp, iMessage or Wi-Fi while you use the local network to browse. Traditional calls and SMS still go through your Italian number.

Should I activate the eSIM before or after I leave?

Install the eSIM at home, on Wi-Fi, before you leave. The data plan then activates automatically when you connect in the United States. That way you are online as soon as you arrive, without looking for airport Wi-Fi or buying a local SIM.

Can I top up or renew the plan for the United States?

Yes. When the data runs out or the validity expires, just buy a new plan — the eSIM profile already installed is kept and does not need to be installed again. You stay connected without interruption.

Can I share the connection (hotspot) in the United States?

Yes. You can share the connection in the United States through a personal hotspot with a computer, tablet or other devices. Shared data is deducted from your plan, so allow a few extra gigabytes if you expect to use the hotspot often.

The United States is a country experienced on a cinematic scale: the Manhattan skyline that takes your breath away, the endless highways of Nevada, the national parks where the signal on your sat nav makes the difference between finding the Grand Canyon and getting lost in the desert. With time zones running from New York to Los Angeles, across six hours of difference, you move quickly and decide at the last second — the restaurant in Charleston, the domestic flight to Miami, the Airbnb in Portland. Without an immediate connection, all of this becomes complicated. With a Datiovunque eSIM activated before leaving Rome, you are already online at your first step on American soil — no queues, no counters, no cards to buy.

Why an eSIM is essential in the United States

The United States is a vast territory where a data connection is not optional: you need it to navigate the interstate highways, book in real time, use Uber in cities where taxis are scarce, and find your way around national parks where paper directions are almost non-existent. Roaming with an Italian SIM in the USA is among the most expensive anywhere — many Italian operators charge rates that exceed €20–30 per day, with frustrating speed limits. With an eSIM dedicated to the United States, you connect directly to local operators such as T-Mobile, AT&T and Verizon, which together cover 93% of the national territory with 4G/LTE and 5G networks. Coverage is excellent in big cities like New York, Los Angeles, Chicago and Miami, and remains solid along the main highways and in the most visited parks. It is also worth remembering that American time is behind Rome by between 6 and 11 hours depending on the coast: having working internet from the moment you land means you can let people at home know you have arrived without desperately searching for free Wi-Fi at the airport.
