You land, and the airport Wi-Fi wants your email address. Your home carrier’s roaming meter is already running. Or you bought a pack by the gigabyte, and it ran dry on day four of a seven-day trip.
For one week in the US, the best eSIM is the one you pay for once, by trip length, and never shop for again. Maya’s 7-day unlimited plan installs once and stays on your phone, and a week in the US needs nothing more than that.
What is the best eSIM for a week in the US? Match it to the traveler
The best eSIM for a week in the US is the one that matches how you travel. A flat-priced unlimited plan suits a visitor who does not want to watch a data meter, and a per-GB pack suits someone who only needs maps and messages. Maya’s 7-day plan is built for the first traveler: unlimited data, one flat price by trip length, installed once. The sections below take each dimension a buyer weighs and name who it serves.
If you land for meetings, the plan is land, connect, go. If you travel with family, it is one less thing to manage. The 7-day plan costs USD 19.99 and includes a daily high-speed data allowance at up to 4G LTE or 5G where local networks offer it. One Maya eSIM works in the United States and 165+ other destinations.
When the 7 days end, the eSIM stays on your phone in an inactive state. For the next trip you buy a new plan, and you skip the reinstall.
How much data does a week in the US really use?
A flat plan removes the guesswork before the trip starts. You pick 7 days and stop budgeting gigabytes.
Maya’s unlimited plans are made for travelers using data on the move. Streaming music or video a few hours a day, social media, browsing, email and messaging are all regular use, and a normal user should have no problems. The high-speed allowance resets every 24 hours, counted from activation. Maya will never charge roaming fees or other charges with its data plans.
Which US network will your eSIM use, and does it matter in a week?
Maya connects you automatically to the best local network, so you do not pick a carrier. We do not name the networks we use in each country. For a one-week visit, that leaves one comparison fewer on your list.
A traveler who needs to select a network manually can contact our support, who can advise which networks are best to connect to. The plan activates once your phone connects to the network. Service in a specific country is not guaranteed and can vary for reasons outside our control. Actual speeds vary by location and local network conditions.
Can you use your eSIM as a hotspot, and what do you need to know about caps?
A visitor who tethers a laptop or shares data with a travel partner should read the hotspot terms before paying. We state what the plan allows up front, so you know the rule on day one and not on day four.
Full hotspot and tethering are included at no extra cost, on both iOS and Android. Using your hotspot for a laptop or tablet to join Zoom calls is regular use. Hotspot is available on all plans, though availability cannot be guaranteed in every situation.
What do travelers say goes wrong with other travel eSIMs?
Travelers describe the same failures again and again: a pack that ran out mid-trip, an install that would not take, a plan priced per country that added up. These are the reviewers’ own allegations, and they are the reasons a flat-priced, install-once plan exists.
In a 2-star Trustpilot review dated October 9, 2026, one customer wrote: “Once connected, the signal strength and data speed was slow at best.” Before you buy any eSIM, find what it says happens after the daily allowance is used.
On setup, in an August 2026 Trustpilot review, Cat wrote: “Simple and efficient install, provided the mobile service as expected in multiple countries without a hiccup in sight.”
How do you install and activate an eSIM before you land in the US?
Install the eSIM before leaving home, then switch it on when you land. Maya installs once and stays on the phone, so a later trip needs a new plan from the app and no new install. Confirm your phone supports eSIM and is unlocked before you buy.
Google’s Pixel Help page says a phone must be SIM-unlocked to work with any mobile carrier, and that all phones in the Google Store come unlocked (Google, Pixel Phone Help). Our compatibility checker is at maya.net/esim-compatible-devices.
On iOS, choose the QR code method in the Maya Mobile app, which is marked Recommended. Scan the code, tap Add eSIM or Add Cellular Plan, and follow the prompts. A QR code installs once, so use it only with a brand-new eSIM. On Android, copy the Manual Activation Code from My eSIMs in your account and enter it exactly as it appears.
When you land, switch the Maya eSIM on and select it for Cellular Data. Data Roaming must be on for the eSIM. Activation takes a minute or two on most phones, and a few minutes on some.
Does a visitor need a US phone number, or is data enough?
Maya plans are data-only, and for a visitor that covers maps, messaging apps and video calls, since those run on data. Our eSIM plans do not include a local phone number. A traveler who must receive a regular SMS or voice call on a US number needs something else, so name which one you are before you buy.
You can browse the web, get directions and use other apps on the plan. You can also keep using your existing number for calls and texts after activating. Some carriers charge international SMS fees even over Wi-Fi calling, so ask your carrier before you leave.
How much does a travel eSIM for one week in the US cost?
Maya’s 7-day plan is USD 19.99, one flat price for the week with unlimited data and a daily high-speed allowance. Set it beside the roaming pass your home carrier publishes for the same seven days.
Each figure below is the carrier’s own, for seven days of daily use in the US. The first is from a page captured October 9, 2026.
- O2 Travel in the UK: £7 a day, £49 for seven days (o2.co.uk, 2026).
- Bell Roam Better in Canada: $13 a day in the US, $91 CAD for seven days (bell.ca, 2026).
- TELUS Easy Roam in Canada: $16 a day in US destinations, $112 CAD for seven days (telus.com, 2026).
- Telstra International Day Pass in Australia: $10 a day on its higher zone, $70 AUD for seven days (telstra.com.au, 2026).
Those passes bill by the day you use your phone. Our plan is one purchase for the seven days. The other lengths are USD 9.99 for 3 days, USD 27.99 for 14 days and USD 49.99 for 30 days.

How Maya covers a US week for USD 19.99 with one eSIM you install once
A one-week visit does not need a per-GB budget, and Maya is built around that. You install one eSIM and it stays on your phone. For each trip you buy a plan by length: 3, 7, 14 or 30 days, all with unlimited data across 165+ countries and a daily high-speed allowance. Each plan is bought once and stops when its days run out. Auto Top-Up is optional and off by default.
Atlas, the globe with the massive passport, has seen worse than a data meter. In a July 2026 Trustpilot review, Edith W. wrote: “Used Maya’s esim for 1 month during my trip to the USA.”
Frequently asked questions
Is unlimited data on a travel eSIM really unlimited?
Our plans give you unlimited data with a daily high-speed allowance at up to 4G LTE or 5G where local networks offer it. The allowance resets every 24 hours, and unused allowance does not carry over. Once it is used, data continues at standard speed, which depends on local network conditions, and no speed is guaranteed. Your data is never cut off entirely.
Can I buy the eSIM before I fly to the US?
Yes. Install it before you fly, then set it as your primary Cellular or Mobile Data plan on arrival. The plan clock starts when you enable the Maya eSIM in your phone settings.
Will my phone work with an eSIM?
Your phone needs to be eSIM-compatible and network-unlocked, and our compatibility checker is at maya.net/esim-compatible-devices. On an iPhone, open Settings, tap General, then About. If “No SIM restrictions” appears next to Carrier Lock, the phone is unlocked (Apple Support, 2026).
What happens when my 7 days end?
The plan ends when its days end, and the eSIM stays on your phone in an inactive state. Auto Top-Up is optional and off by default. If you turn it on, it buys the same plan again when the current one expires, and you can turn it off any time from My eSIM.
Can I use the same eSIM on my next trip abroad?
Yes. You install it once, it stays on your phone, and for each trip you buy a new plan with no reinstalling. One eSIM covers 165+ countries.
What should I check before buying any travel eSIM for the US?
Check that your phone is unlocked and eSIM-compatible. Read how the plan describes its daily allowance and what happens after it. Find out whether it includes a phone number, since ours does not. Check the refund terms too: we offer a money-back guarantee if the eSIM cannot be installed or used, on the conditions in the return policy.
Maya sells one global travel eSIM with unlimited data across 165+ countries, so a week in the US is one flat price you pay once by trip length.
