Why buy before you fly
Buying a USA eSIM before departure is the simplest way to arrive connected. You install it at home, keep your usual number for calls and messages, and switch the eSIM on when you land. No kiosk, no queue, no plastic SIM to swap out of your phone.
It also keeps the cost predictable. A prepaid travel eSIM is bought up front, so you are not relying on your home operator's roaming rates for maps, ride-hailing and messages.
What the United States eSIM covers
The USA plan is the one to buy for a single-country trip. It is a data plan for the United States, sold in the USA store on esimamericas.com. Buy it here: United States eSIM.
If your itinerary crosses a border, look at the North America plan for the USA, Canada and Mexico instead, so one eSIM covers the whole trip.
A quick way to choose:
| Your trip | What to buy |
|---|---|
| United States only | United States eSIM |
| USA plus Canada and/or Mexico | North America plan |
| Arriving first in Canada | Canada eSIM |
Check your phone first
Most recent phones take an eSIM, but not all, and some models sold in certain markets do not. It takes about a minute to check: open your phone's settings and look for the option to add an eSIM or a mobile data plan. Our guide walks through it: Will your phone take an eSIM?.
If your phone is not eSIM-ready, a physical SIM is still the option for that device.
Install at home, switch on after landing
Install the eSIM while you have reliable Wi-Fi, ideally the day before you fly. The installation guide takes you through scanning the QR code, and the activation guide explains when to switch it on.
One habit that saves trouble: leave your home SIM active for calls and messages, and set the eSIM as the line for mobile data. That way your bank's verification texts still arrive while your maps use the travel plan.
Arriving in the USA
At a major airport, the practical sequence is the same everywhere: clear immigration, collect bags, then check your phone has picked up a network before you leave the terminal. If it has not, the not-connecting guide covers the usual fixes.
If you are flying into New York, our arrival guide for JFK covers what to expect and how to get online on the way into the city. For a wider city guide, see New York eSIM.
What you will use data for
In the USA, the data you will actually lean on is maps and transit, ride-hailing, restaurant and ticket bookings, and messaging home. Hotel and cafe Wi-Fi is common, but you do not want to depend on it for the first hour after landing or when you are out for the day.
If you want to know which networks your phone will connect to, see our note on AT&T in the USA.
Beyond the cities
Coverage in and around major cities and along the main intercity routes is generally good. In national parks and remote areas, expect gaps, as you would with any network. If your trip includes the Rockies and the parks, our Banff eSIM guide is a useful companion for planning around them.
For a city break built around resorts and shows, see Las Vegas eSIM.
If you are continuing south
Many travellers pair a USA trip with Latin America. If your route continues into Mexico, Central America or South America, check the plan that matches that leg before you buy, so you are not buying twice. Our help centre has the setup and troubleshooting guides in one place.
Practical checklist
- Check your phone takes an eSIM.
- Buy the United States eSIM, or the North America plan if you are crossing borders.
- Install it on Wi-Fi before you fly.
- Set the eSIM as your data line and keep your home SIM for calls and texts.
- Switch it on after you land and check you have a signal before leaving the airport.
Buying and after-sales
Plans are bought in the store, and the order confirmation and QR code arrive by email. If you lose the email, the help centre explains what to do; there is no public order lookup page. Refunds and lost QR codes are covered in the refunds guide, and the refund policy sets out the terms.
