eSIM for the United States
For two weeks in the United States, 5,90 € with 3 GB covers most people. A month of normal use, 6,90 € with 5 GB. It runs on Verizon and AT&T, with coverage across the whole country. The comparison that matters: Movistar's daily rate for the United States is 6,05 € a day for 500 MB, checked on 22 August 2026.

You walk out of baggage claim at JFK. You have thirty seconds to decide whether to jump in a yellow cab, order a car through the app or find the AirTrain, and all three need internet. Behind you are two hundred people doing the same maths with the same face.
What not carrying one costs
The United States isn't the European Union, so “roam like at home” doesn't apply and your Spanish tariff doesn't travel with you. Each operator charges its outside-the-EU rate, and it's better to look the figure up before you fly rather than on the bill when you're back.
| Two weeks of travel | What you pay | The data you get |
|---|---|---|
| Movistar's daily rate, used on 14 days | 84,70 € | 500 MB a day |
| Zas eSIM, 15 days | 5,90 € | 3 GB for the whole trip |
| Zas eSIM, 30 days | 6,90 € | 5 GB for the whole trip |
No need to dress it up. It's the same fourteen days and the same coverage, because the network underneath is the American operators' in both cases.
How many gigabytes you need
A trip to the United States leans heavily on maps, ride apps and looking places up. All of that uses little: a whole day of navigating comes to about 100 MB. What sends the total soaring is video and uploading photos, and that tends to happen at night on the hotel Wi-Fi.
| Plan | Price | Who it's for |
|---|---|---|
| 7 days · 1 GB | 2,90 € | A week with Wi-Fi at your accommodation |
| 15 days · 3 GB | 5,90 € | The typical two-week trip |
| 30 days · 5 GB | 6,90 € | A month, or a long road trip |
| 30 days · 10 GB | 11,90 € | Two people sharing, or heavy use |
| 30 days · 20 GB | 20,90 € | Working from there |
If you'll be driving long distances, allow a little more: the sat nav stays on for hours and recalculates constantly. Still small next to video, but it isn't zero.
Which networks it uses
Verizon and AT&T, with 4G and 5G. They're two of the three national operators, so coverage runs coast to coast: cities, interstate highways and most of the national parks, where the signal dips for everyone alike.
In the canyons and the remote stretches of the west there's no coverage from anyone. If your route goes through there, download the maps before you leave the last town.
Install it before you fly
- Buy it and get the QR by email, instantly.
- Install it at home, on Wi-Fi. Installing needs a connection; activating doesn't.
- When you land, switch on the data line and turn off roaming on your Spanish SIM.
- The days count from the first connection to an American network, not from purchase.
Does it give me an American phone number?
No. The plans are data only: no US number, no SMS. Your Spanish number keeps working for calls and WhatsApp, because the eSIM goes in as a second line and your usual SIM stays where it is.
Does it cover the whole country, or do you buy by state?
The whole country. A single eSIM covers all fifty states; nothing changes when you cross from Nevada into California or fly from New York to Los Angeles.
Does it work in Hawaii, Alaska or Puerto Rico?
Verizon and AT&T coverage reaches those territories, though exact availability can vary. If your trip is mainly to one of them, it's worth checking before you buy.
Can I share the connection with a laptop?
Yes. The United States plans allow hotspot sharing, so your phone can be the access point for a laptop or another phone. Whatever they use comes out of the same gigabytes.
What about calls to American numbers?
With data you can call over WhatsApp or any voice app, which is how almost everyone calls. Dialling an American number from your Spanish line would fall under your operator's international rate.
