What is the best eSIM for the United States?

Maya’s Global eSIM is the best eSIM for the United States if you want unlimited data at one flat price for your trip length. It covers 165+ countries, starts at USD 9.99 for 3 days, and you install it once.

A US trip shouldn’t start with decoding a catalog of plans and gigabyte packs before the plane lands.

Maya’s Global eSIM is the best US eSIM for flat-price unlimited data

Pick 3, 7, 14 or 30 days, pay one price, and you’re covered. One plan works in the United States and 165+ other countries, with no extra purchase. The eSIM stays on your phone after you land and after you fly home.

That suits the avid traveler, the business traveler and the family that wants one less thing to manage. Airalo, Holafly, Saily and Nomad each publish per-country and per-region plans, and Saily and Nomad sell by the gigabyte. We sell one plan, priced by trip length.

Colin J. gave Maya Mobile five stars on Trustpilot on February 12, 2026: “Used in so many countries and it is just perfect and very reasonably priced. If u have any problems the support service is first class too”

How much does Maya’s US travel eSIM cost for 3 to 30 days?

Maya’s unlimited plan costs USD 9.99 for 3 days, USD 19.99 for 7, USD 27.99 for 14 and USD 49.99 for 30. The price is the same in every country, so a US trip costs what a trip anywhere else costs.

The 30-day price comes from Maya Mobile’s Global eSIM Coverage page. The 14-day plan suits holidays and two-week trips.

Visiting from abroad, you already have a home-carrier option to weigh. According to O2’s website, its Zone 2 destinations, which include the USA, cost a fixed £7 a day, so 7 days of daily use comes to £49. According to Bell’s website, Roam Better is $13 a day in the U.S., which makes 7 days $91 CAD. Maya’s 7-day plan is USD 19.99.

A longer trip needs a longer plan. Buy it on the same eSIM, with no reinstall. Pay once, land, and spend the trip on the trip.

What does unlimited data mean on a US travel eSIM?

You stay connected every day of your plan. Each day starts with a high-speed allowance, the Daily Quota, at up to 4G LTE or 5G where local networks offer it. When it’s used up, data continues at standard speed for the rest of the day.

Our terms say it in one sentence: “Your data is never cut off entirely.” The allowance resets every 24 hours, counted from the moment your plan starts. Because you cross time zones, the reset usually doesn’t land at midnight.

Speeds after the Daily Quota depend on local network conditions, and we don’t guarantee specific speeds. Unused quota doesn’t carry over. Our fair-usage guidelines add that download and upload speed can drop to 10 Mbps on a day over 3 GB, and to 1 Mbps if very high use continues. Any throttle comes off within 24 hours.

Most trips don’t get near that. Roamly’s 2026 guide puts Google Maps navigation at 5MB to 10MB an hour (Roamly, 2026). A WhatsApp or FaceTime video call runs 300MB to 500MB an hour (Roamly, 2026). Messaging costs about 5KB per message (SimSignal, 2026).

How do you install a travel eSIM before landing in the US?

Install the eSIM on your phone before you fly, and it stays on the phone. Each trip needs a plan, and the eSIM and its setup stay, so the next trip is a new plan and nothing else. Maya’s Help Center quick start guide gives the steps in this order.

1. Buy an eSIM data package for the country where you’re traveling or currently located.
2. After purchase, you’ll usually get a QR code by email within 5 minutes.
3. On iPhone, tap and hold the QR code and select Add eSIM, or scan it with the Camera app. If scanning fails, use manual activation.
4. On iPhone, follow the prompts to install the new Data Plan. The default options are okay.
5. Name the eSIM plan, for example “Maya eSIM” or the country you’re visiting.
6. Choose Primary for Voice/SMS and iMessage, and use the Maya Mobile eSIM for Mobile Data only.
7. Set Data Roaming to ON for the eSIM in Settings. You can turn it OFF on your Primary line.
8. Select Data Mode, then Low Data Mode, to conserve data.
9. On Android, open the Camera app, point it at the QR code and tap the notification that says Data Plan.
10. On Android, follow the prompts to install the new Data Plan. The default options are okay.
11. On Android, set Data Roaming to ON in your phone’s Settings.
12. Turn off Data Roaming on your Primary line (your home SIM) to prevent roaming charges.
13. If you installed before arriving, set the eSIM as your primary Cellular / Mobile Data plan when you arrive.
14. IMPORTANT: Turn on Low Data Mode (iPhone) or Data Saver mode (Android) to prevent background data.
15. Once active, the connection usually establishes immediately, showing 5G or 4G LTE. In rare cases it takes up to 15 minutes. After 15 minutes, use the eSIM Connection Troubleshooting Guide.

To check it, go to Settings > Cellular (Mobile Data in the UK), tap Cellular Data and select the eSIM plan. Done! You’re online before the baggage carousel starts.

Rachel T. gave Maya Mobile five stars on Trustpilot on March 31, 2026: “Very easy to set up. Worked immediately on arrival at Punta Cana. I had the opportunity if I wanted to top up but I didn’t need it.”

What should you check before you buy an eSIM for the US?

Check three things: calls and texts, hotspot and how the eSIM picks a network. Maya’s Global eSIM is data only, so you keep your own number for calls and texts, and Mobile Hotspot or Internet Sharing lets your other devices use the data where supported.

If your carrier supports Wi-Fi Calling and you’ve turned it on, your phone reaches your home network over the eSIM’s data connection. Calls and texts then run on your regular number. On network choice, we connect you to the best available local network, and you follow the rules of any roaming network you use through us.

Service in any one country isn’t guaranteed and can vary for reasons outside our control.

Then check what the plan is tied to. A one-star Trustpilot review of Nomad from October 9, 2026 reads: “Purchased a 5 G plan for Bermuda. Was chatting with an agent for about an hour as it wouldn’t work. (My phone is compatable and I had a plan from them that expored which worked. ) After all that time they asked for 24 hours to troubleshoot and get back to me. So I asked for a refund that they say may take up to two weeks.”

With ours, the plan is the Global plan, and it works where you land.

What does a US eSIM do for a business trip or a month-long stay?

For a business traveler it’s land, connect, go: the eSIM is already on the phone when the plane lands. A digital nomad or a long stay picks the 30-day plan at USD 49.99, marked Best Value, and keeps the same eSIM for the next trip.

Install before you fly, then switch the eSIM on and select it for Cellular Data when you land. The plan clock starts when you enable the Maya eSIM in your phone settings, so the days count from the moment you flip it on. That lets you install early and start the clock when the trip does.

When a plan expires, the eSIM stays on the device in an inactive state. Re-enable it in your device settings to use data again. For a stay that runs past 30 days, buy the next plan on the same eSIM.

Our unlimited plans are made for individual travelers using data on the move. They aren’t intended for automated use, high-frequency use or large file transfers, and Wi-Fi is better for those jobs. Calls, maps and the inbox are what the plan is built for.

What travel eSIM sellers publish on plans and pricing for a US trip

The table lists what each seller publishes on how its plans are sold and priced, copied from the company’s own statement. Maya shows one plan by trip length. The others show catalogs.

The Airalo, Holafly, Saily and Nomad cells use each company’s own wording or a short summary of it, and the Maya Mobile cells use Maya’s own plan terms.

Why Maya Mobile turns a US trip into one install and one flat price

We’re a travel eSIM company. One eSIM, permanently installed on your phone, gives you unlimited data in 165+ countries and 20+ cruise lines. Cruise coverage is the Global + Cruise plan, bought as its own plan. Plans come in 3, 7, 14 and 30 days, priced by trip length instead of by country or by the gigabyte.

Amy A. gave Maya Mobile five stars on Trustpilot on February 27, 2026: “I’ve used Maya in multiple countries and their service is always great. When I’ve had issues it has been resolved quickly and with easy to follow instructions.”

Pick your days, install once and land ready.

What is a travel eSIM and how does it work in the US?

A travel eSIM is a digital SIM built into your phone, so you connect to a network without a physical card. According to AT&T, service information is downloaded and activated digitally, and then the phone connects the way it would with a physical SIM. Our Global eSIM works in the United States and 165+ other countries, and a plan on it sets the days.

Does my phone need to be unlocked and eSIM-compatible?

Yes. If your device isn’t eSIM compatible, we can’t provide service to you.

Is an eSIM better than a physical SIM for a short US trip?

Yes, for most short trips. Apple’s 2024 support page says that with eSIM you don’t need to obtain, carry and swap physical SIM cards, or wait for them to arrive by mail (Apple Support, 2024). The FCC’s 2025 FAQ adds that no tools are required, because there’s no physical card to reach (FCC, 2025). It also can’t be removed if your iPhone or iPad is lost or stolen (Apple Support, 2024).

Does my Maya plan renew on its own?

No. Every plan ends when its days end, unless you turn on Auto Top-Up. Auto Top-Up is opt-in and off by default. With it on, the same plan is bought again when the current one expires, and with it off, there’s no further charge.

Can I use the same Maya eSIM on my next trip?

Yes. Keep the eSIM on your phone, buy a plan for the next trip and enable the eSIM in your settings. It’s data only, so your own number keeps handling calls and texts.
