894 of these 1654 plans were checked against the seller's own shop on 17 October 2026. The rest come from the seller's own feed or plan pages and are not yet independently checked.
The Watchdog Pick is chosen automatically: the lowest real price per GB of the 1654 plans in this view. Bulk data pools above 50 GB cannot win it, because their per GB rate only exists if you use data no traveller uses. Providers cannot pay for it, and a commission never changes the ranking. Prices are shown in USD and can change at checkout.
Price per GB counts only data you can use inside the validity, at most 3 GB a day, so a big pool on a short validity cannot buy the top spot. Every provider's best two plans come first, then the rest. A plan marked Unverified price undercuts every other provider here by more than half and waits at the end until we have checked it on the seller's site. How we rank
Unlimited rows show the daily amount at full speed. Some rows also show the speed after that amount. A row with no speed does not mean the plan stays fast, so check the plan on the seller's site.
Some links here earn us a commission. It never changes the order. How we make money The row marked Sponsored is a paid placement shown above the ranking, not part of it. Advertise here.

Cheapest eSIM for USA: the numbers
As of 17 October 2026, 06:01 GMT, the cheapest eSIM for USA is Lempart Flex with 45 GB for 15 Days at $20.49. That is $0.46 per GB, the best rate of the 1654 plans we compare from 57 providers. 1081 plans include 5G. 610 support top ups. That timestamp is the exact moment of our latest price check, and the table above always shows the live order.
Which is the best eSIM for USA?
There is no single best eSIM for USA, because the right plan depends on how long you stay and how much data you use. What we can do is rank the 1654 plans on the numbers, as they stand on 17 October 2026:
- Best value overall Lempart Flex, 45 GB for 15 Days at $20.49. That is $0.46 per GB, the lowest real rate of every USA plan we track.
- Best for a short trip eSIM4Travel, 1 GB for 1 Day at $0.68. The cheapest ticket that still gives you at least 1 GB for a week or less.
- Best for a long stay SparkRoam, 50 GB for 30 Days at $25.56, $0.51 per GB. The best rate among plans that last 30 days or more.
- Highest daily cap on an unlimited plan SimSmash, 1 Day at $6.99, full speed up to 10 GB a day. Set that daily cap against the fixed plan above before you pay for the word unlimited.
None of these picks is chosen by a person. Each one is the first row of a sort on live prices, so it changes whenever a provider moves a price, and Lempart Flex did not pay to be named here.
Which mobile networks does USA have?
More than 90 percent of the US population lives in areas with good 5G coverage, though geographic coverage is far lower because the country is huge and thinly populated outside cities.
- Verizon: Verizon runs the largest 4G LTE footprint in the country, reaching roughly 70 percent of US land area, which keeps it the coverage leader in rural and remote regions.
- T-Mobile: T-Mobile has the widest 5G network of the big three, reaching about 98 percent of the US population, and posts the fastest average data speeds in cities.
- AT&T: AT&T sits between the other two, with a 5G network that reaches more than 316 million people and 4G coverage close behind Verizon's.
Prepaid brands and travel eSIMs all ride the big three networks, so check which host network your eSIM connects to before you buy.
The eSIM plans we compare on this page connect to:
The list above is USA's operator market. The badges are the networks our tracked plans actually roam onto, which can be a subset of it, and the same network is sometimes sold to roaming partners under a different brand name. So a guide praising an operator you do not see badged here is describing a local SIM, not the travel eSIMs compared above.
Is 5G available in USA?
All three national carriers run mature 5G networks. T-Mobile leads on reach with about 98 percent population coverage, and 5G works in virtually every city and along most interstates.
How much data do you need in USA?
Light use is about 500 MB a day. That covers maps, messages, and some browsing. Normal use with photos, social apps, and short videos runs 1 to 1.5 GB a day. Streaming and hotspot use can eat 2 to 3 GB a day. Here is what each size costs in USA right now:
Are unlimited eSIMs for USA really unlimited?
Not always. 639 of the 1654 plans above are sold as unlimited, and most of them carry a daily fair use cap. A further 25 plans are unlimited in a different way: one capped speed for the whole plan, shown next to the word Unlimited in the table. For USA the caps we can see published are 0.2 to 10 GB a day: past that the speed drops, often to 1 Mbps or less, until the clock resets. That is fine for messages and maps, slow for video. At $0.46 per GB from Lempart Flex, a fixed plan often works out cheaper than unlimited unless you genuinely burn several GB a day. That is why we rank by price per GB and not by the word on the label.
Here is what each seller on this page actually allows per day before it slows you down. No seller publishes this next to its rivals, which is exactly why it is worth showing.
Every seller that publishes a daily allowance is listed on our daily data caps page, with the cheapest plan at each one. The gap between the top and bottom of that table is the whole point. Two plans both sold as unlimited can differ several times over in what you actually get at full speed, and the cheaper one is not always the smaller allowance.
eSIM or a local SIM card at the airport in USA?
An eSIM is ready before you land. No queue, no shop, no handing over your passport at a counter for a tourist SIM card. Data for USA starts at $0.20 on this page, which is hard for airport kiosks to beat. A local SIM still makes sense if you need a local phone number or plan to stay for months. For a normal trip, the eSIM wins on price and effort.
Setting up your USA eSIM
Pick the plan, not the brandThe cheapest rate in USA today is $0.46 per GB from Lempart Flex, against a median of $1.56. The QR code arrives by email within minutes of paying.
Install before you flyScan the QR code on wifi at home. Installation needs a connection, and the one thing you will not have when you land in USA is a working connection.
Turn it on when you landEnable the eSIM and turn on data roaming for it, then give it a minute to attach to AT&T, T-Mobile, T-Mobile USA, US Cellular, Verizon. Expect 5G where the network reaches, 4G everywhere else.
Know what happens when it runs out610 of the 1654 plans here can be topped up, so running out is not the end of the trip. If you would rather over buy than top up, the cheapest plan with at least 5 GB is ASIMGO at $3.43.
Good to know before you land in USA
The US has no SIM registration law, so you can buy and activate a prepaid SIM without showing ID.
Airport SIM options are poor. JFK has unstaffed vending machines charging around 29 USD for just 1 GB, and LAX has a single shop selling physical SIMs only, so most travellers are better off with an eSIM bought before landing.
T-Mobile is excellent in cities but its 4G network covers only about 62 percent of the country, so for road trips through rural states Verizon or AT&T coverage is the safer bet.
USA Travel eSIM FAQ
Everything you need to know about using an eSIM in USA
What is the cheapest eSIM for USA?
Right now the cheapest option ranked by price per GB is Lempart Flex with 45 GB for 15 Days at $20.49. That works out to $0.46 per GB. Prices change often, so the table above is re-sorted at every price check.
Which is the best eSIM for USA?
It depends on the trip, so we rank rather than pick a favourite. On today's prices the best value for USA is Lempart Flex at $0.46 per GB, the lowest real rate of the 1654 plans we compare. For heavy daily use there are 639 unlimited plans, most with a daily fair use cap, and they only win if you genuinely burn several GB a day. Every pick on this page is the first row of a sort on live prices. No provider can pay to be named best.
Is eSIM available in USA?
Yes. We track 1654 prepaid travel eSIM plans from 57 providers that work in USA, roaming onto AT&T, T-Mobile, T-Mobile USA, US Cellular, Verizon. You need a phone that supports eSIM and is not locked to a carrier; most iPhones from the XS onward and most flagship Android phones from 2019 on qualify.
Which networks will my eSIM connect to in USA?
The plans we compare connect to AT&T, T-Mobile, T-Mobile USA, US Cellular, Verizon. The exact network depends on the plan you pick. Check the plan details before you buy if one network matters to you.
Do USA eSIMs support 5G?
1081 of the 1654 plans we track for USA include 5G where the local network offers it. The rest run on 4G, which is still fine for maps, calls over apps, and video.
Can I buy a USA eSIM online before I travel?
Yes, and you should. Every plan on this page is sold online and delivered by email as a QR code within minutes. Install it on wifi at home, leave the line switched off, and turn on data roaming for it when you land in USA. The validity clock on most plans only starts when the eSIM first connects.
Can I top up my USA eSIM if I run out?
Yes. 610 of the 1654 plans here support top ups, so you can add data without buying a new eSIM. The rest need a fresh plan once the data ends.
Is an eSIM cheaper than a local SIM card in USA?
For a trip of days or weeks, usually yes. Data for USA starts at $0.20 for 100 MB on this page, with no queue, no shop and no passport handed over at a counter. A local SIM card can still win if you stay for months or need a local phone number.
Will I still receive bank SMS and OTP codes?
Yes, if you keep your home SIM active. Travel eSIMs are data only. Your phone can hold both at once, so leave your normal SIM on for SMS and use the eSIM for data. Turn off roaming data on the home SIM to avoid charges.
Do these eSIMs include a phone number or calls?
The plans we compare are data only, so there is no local number. Calls work fine over WhatsApp, FaceTime, or any app that uses data. If you need a real local number, a local SIM is the better tool.
Does a USA eSIM work on iPhone and Android?
Yes, on any carrier unlocked phone with eSIM support: iPhone XS or newer, Google Pixel 3 or newer, Samsung Galaxy S20 or newer and most recent flagships. The plans are identical on both; only the install steps differ, and both take about a minute on wifi.
How many GB do I need for a week in USA?
Around 3 to 5 GB covers a week of maps, messaging, and normal browsing. Heavy video or hotspot use needs 1 to 2 GB per day. Today the cheapest plan with at least 5 GB is ASIMGO at $3.43.
Which USA eSIM gives the most data per day?
Of the plans sold as unlimited here, SimSmash allows the most at full speed, 10 GB a day from $6.99. The smallest allowance on this page is ASIMGO at 200 MB a day. Every one of them is advertised as unlimited, and past the daily allowance the speed drops, often to 1 Mbps or less, until the next day. Check the allowance, not the word.
