Best eSIM for the USA: Data From €2.99 vs US Prepaid SIMs

Quick answer: which eSIM should you get for the USA?

Most visitors don't need a US SIM card. A travel eSIM gives you mobile data the moment you land, and you can install it at home before you fly. A US prepaid plan makes sense if you need US calls and texts or a lot of data for a month or longer.

• eSIMFOX USA eSIM: from €2.99 (1 GB, 7 days). 10 GB costs €15.99 and 20 GB costs €19.99, each for 30 days, on the AT&T, T-Mobile and Verizon networks (product page, as of November 6, 2026).
• US prepaid plan made for visitors: T-Mobile's U.S. Pass costs $25 for 7 days (about €22.27) plus taxes and fees, with unlimited talk and text in the US, Mexico and Canada. You buy and activate it in the US, and your phone must be unlocked and eSIM-compatible (T-Mobile).
• Also visiting Canada or Mexico? The eSIMFOX North America eSIM covers all three countries. For the US alone, the USA eSIM is cheaper at every size.
• Check your phone first: AT&T, T-Mobile and Verizon have switched off 3G (FCC), so you need a 4G or 5G phone.

US prepaid SIM and eSIM plans for tourists (as of November 6, 2026)

The three big US networks are AT&T, T-Mobile and Verizon. All three sell prepaid plans without a contract. We only list prices shown on their own websites today. Taxes and fees come on top. Euro values use the ECB reference rate of November 5, 2026 (€1 = $1.1224).

T-Mobile U.S. Pass: the official plan for visitors

T-Mobile launched the U.S. Pass for international travelers in May 2026 (T-Mobile newsroom). According to T-Mobile's U.S. Pass page, it works like this:

• You buy it in the T-Mobile Prepaid eSIM app or on T-Mobile.com. You must buy and activate it while you are in the US. No store visit is needed.
• No ID or paperwork is required. T-Mobile accepts domestic and international credit or debit cards from select countries.
• Your phone must be unlocked and eSIM-compatible, and you need Wi-Fi to install the eSIM.
• The pass is void if you don't activate it within 90 days of purchase. Canada and Mexico get 5GB of high-speed data through a free add-on.

Looking for the T-Mobile Tourist Plan?

We could not find a Tourist Plan on T-Mobile's website on November 6, 2026. T-Mobile's current offer for international visitors is the U.S. Pass above.

AT&T and Verizon prepaid

Both sell monthly prepaid plans. AT&T says its prepaid plans need no contract or credit check, and some of its offers are online only (AT&T Prepaid). Verizon says you can also use eSIM to activate a prepaid plan, and it points you to Verizon stores and local retailers. Its Auto Pay discount only starts after the first month, so a one-month visitor pays the full price (Verizon Prepaid).

eSIMFOX USA eSIM: prices and details (as of November 6, 2026)

According to the eSIMFOX USA product page, the eSIM uses the AT&T, T-Mobile and Verizon networks with 4G/5G where available. It is data only, so you don't get a US phone number. No ID verification (eKYC) is needed. The validity starts with the first network connection in the USA, not when you buy, and you can top up without a new eSIM. Support is available 24/7 via WhatsApp. The plan pages list hotspot/tethering as supported (10 GB plan).

Tip: 20 GB costs only €4 more than 10 GB. The unlimited plans give you 2 GB per day at full speed. After that, the speed drops to up to 1 Mbps until the next daily reset (Unlimited 7 days plan).

USA eSIM or North America eSIM?

For a US-only trip, the USA eSIM is the cheaper choice. The North America eSIM is worth it if you also cross into Canada or Mexico, because one eSIM covers all three countries. Its page names Movistar, AT&T and Altan as networks. More on the neighbors: best eSIM for Canada and best eSIM for Mexico.

Travel eSIM or US prepaid SIM: which is cheaper?

It depends on how long you stay and whether you need US calls. Here is a fair comparison with the prices above (as of November 6, 2026; US prices plus taxes and fees):

• Pick a travel eSIM if you want data only, the lowest price for a normal trip and everything set up before you fly. Your home number stays active for calls and texts.
• Pick a US prepaid plan if you need US calls and texts, or a lot of data for a month or longer. Remember that T-Mobile's U.S. Pass can only be bought and activated once you are in the US.

Before you fly: will your phone work in the USA?

• No more 3G. AT&T phased out 3G from February 2022, T-Mobile shut down its 3G UMTS network on July 1, 2022, and Verizon finished by December 31, 2022. The FCC warns that international visitors with 3G phones will be affected (FCC).
• eSIM support. Check that your phone supports eSIM in our compatibility list. For T-Mobile's U.S. Pass, it must also be unlocked.
• Buying an iPhone in the US? Apple says iPhone 14 models or later purchased in the United States can only be activated with an eSIM (Apple). There is no SIM tray, so plan to use an eSIM back home too.
• Coverage for road trips. The FCC's National Broadband Map shows 3G, 4G and 5G coverage of each mobile provider for any address, outdoors or in a vehicle (FCC help). Handy before you drive into national parks or remote areas.

How much data do you need in the USA?

The data calculator on our product pages starts at about 0.5 GB per day for maps, messages and browsing, adds a 20% reserve and rounds up. Video changes the math fast: Netflix says HD streaming uses up to 3 GB per hour, while its mobile "Automatic" setting gives you about 4 hours per GB (Netflix).

Streaming every day or sharing your connection with a laptop? Take the 40 GB or 50 GB plan, or an unlimited plan with 2 GB per day at full speed.

How to set up your USA eSIM

1. Check that your phone supports eSIM: compatibility list.
2. Buy your plan at home and install the eSIM over Wi-Fi by scanning the QR code. The validity only starts with your first connection in the USA, so installing early costs you nothing.
3. When you land, turn on the eSIM line, choose it for mobile data and turn on data roaming for it.
4. Keep your home SIM on for calls and texts, but turn off data roaming for it to avoid roaming charges.

Forgot to install it? Use the free airport Wi-Fi to buy and install it on arrival: see our guides to JFK Airport Wi-Fi and Atlanta (ATL) Airport Wi-Fi. Step-by-step help is in the eSIM installation guide, and if something doesn't connect, see why is my eSIM not working?
