USA eSIM: The Complete 2026 Guide for Travelers

Landing in the United States without mobile data means no Uber pickup, no live directions out of the airport and no way to check in to your hotel on the go. A USA eSIM fixes that before you board: you buy a prepaid data plan online, get a QR code by email, install it at home and connect to a US network the moment you land. This guide covers everything you need to know — which phones work, which networks you will use, how much data to buy and how to fix the few problems that come up.

What a USA eSIM is — and what it is not

An eSIM is a digital SIM profile that your phone downloads instead of a plastic card. Our USA plans are data-only: you get mobile internet for maps, rides, messaging and bookings, but no US phone number. That is usually what travelers want. Your home SIM stays in the phone, so you keep receiving texts such as bank verification codes, while all your data runs over the eSIM. Calls work through WhatsApp, FaceTime and other apps.

USA plans route your data through the United States, so apps and websites see a US IP address.

Check your phone first

Two things matter: the phone must support eSIM and it must be carrier-unlocked. Most phones from roughly the last six years support eSIM, including:

• iPhone: iPhone XR, XS and every newer model, including the SE (2nd generation and later).
• Google Pixel: Pixel 3 and newer.
• Samsung Galaxy: Galaxy S20 and newer, plus recent Z Fold and Z Flip models.
• Many other recent Android phones — support varies by model and the country where the phone was sold.

Quick check: on an iPhone, open Settings › Cellular and look for Add eSIM. On any phone, dialing *#06# shows an EID number if the phone has an eSIM. If your phone came from your carrier on contract, ask them whether it is unlocked before you buy.

Which networks you will use

USA eSIM plans connect to Verizon and AT&T, two of the largest networks in the country. Your phone picks the stronger signal automatically. Expect 5G in many cities and 4G LTE across most populated areas and along interstate highways. Like any US carrier, coverage thins out in deserts, mountains and large national parks — our road trip coverage guide explains where to expect gaps.

How much data to buy

For a typical city trip with maps, rides, messaging and some social media, plan on about 1 GB per day. Light users who mostly use Wi-Fi at the hotel can get by on far less; people who video call home every day or watch video on the go should plan for 2 GB or more per day. Our data guide breaks this down by activity and trip length. Plans marked Top-up can be refilled later, so you do not have to guess perfectly.

Installing your eSIM, step by step

1. Install before you fly, while you are on Wi-Fi. Installing does not start the plan.
2. On iPhone go to Settings › Cellular › Add eSIM › Use QR Code; on Android open Settings › Connections (or Network) › SIM manager › Add eSIM. Scan the QR code from your email or from the My eSIM page.
3. Give the new line a label such as “USA” so it is easy to recognize.
4. Choose the eSIM for mobile data, and keep your home SIM as the default line for calls and texts.
5. Turn on data roaming for the eSIM line. A travel eSIM connects as a visitor on US networks, so roaming must be on — it costs nothing extra because the data comes from your prepaid plan. Keep data roaming off for your home SIM so your home carrier has nothing to charge you for.

Your plan’s validity starts when the eSIM first connects to a network in the United States, not when you install it.

Quick fixes if data does not work

• No data at all: check that data roaming is on for the eSIM and that the eSIM is selected for mobile data.
• Still nothing: switch airplane mode on and off, or restart the phone.
• Weak or no network: turn off automatic network selection and pick Verizon or AT&T manually.
• Connected but slow: check your remaining data on the My eSIM page; if the plan is used up, top it up or buy a new plan.

If none of that helps, contact us with your order email — we reply within 24 hours.

Frequently asked questions

Do I get a US phone number with the USA eSIM?

No. The eSIM is data-only. Keep your home SIM for calls and texts, and use WhatsApp, FaceTime or similar apps to call over data.

When should I install the eSIM?

Install it before you travel while you are on Wi-Fi. The plan only starts when the eSIM first connects to a network in the United States.

Does the USA eSIM cover the whole country?

It uses the Verizon and AT&T networks, which cover cities, towns and major highways across the country. Remote deserts, mountains and parts of national parks can have weak or no signal.
