I’m based in the US, and barely a month goes by without a friend flying in and asking how to get their phone working here. My answer has changed a lot lately. For years I’d send people to an airport kiosk, but in 2026 I usually tell them to set up an eSIM before they board, since it activates the second they land and skips the whole counter.
That said, a physical SIM card still makes sense for some travelers, especially anyone on an older or carrier-locked phone. So this guide covers both, with a quick framework to help you decide in about thirty seconds. After that, I’ll give you my tested picks for the best prepaid SIM card for the USA, along with the eSIMs I recommend most.

Check This Before You Buy
If you have a recent iPhone, a physical SIM card may not even be an option. Every US model from the iPhone 14 onward (including the 15, 16, and 17) ships with no SIM tray at all, so it’s eSIM-only. The iPhone Air is eSIM-only everywhere too. Phones bought outside the US usually still have a nano-SIM slot, but if yours doesn’t, skip straight to the eSIM picks below, since that’s your only route. Either way, make sure your phone is carrier-unlocked first.

eSIM or physical SIM? How to decide
Before you buy anything, here’s the quick gut check I give friends. For most people in 2026 an eSIM is the easier choice, but a physical SIM still has its place.
| Go with an eSIM if… | Go with a physical SIM if… |
|---|---|
| You have a recent iPhone or newer Android with no SIM tray | You have an older or budget phone without eSIM support |
| You want it working the moment you land | You’re fine setting it up at an airport kiosk |
| You’d rather buy and activate from home | You want to pay cash in person |
| You hate fiddling with tiny cards | You want a card you can pop into a backup phone |
| You’re hopping between several countries | You’re staying put in the US the whole trip |
If you landed mostly in the left column, jump to my eSIM picks below. If the right column sounds more like you, the physical SIM cards further down are where to look.
Why buy a prepaid SIM or eSIM for the USA?
The appeal of a prepaid SIM or eSIM is simple. You pay only for what you need, with no contract, no credit check, and no surprise roaming bill when you get home. You can often keep your own number, top up whenever you want, and have working data the moment you land for maps, rideshares, and staying in touch. For a short trip, it’s almost always cheaper and less hassle than letting your home carrier charge you international rates.
Where to buy a prepaid SIM or eSIM for the USA
The easiest option in 2026 is to sort your data before you even pack. Most travelers now buy an eSIM online from a provider like Airalo or Saily, install it in a couple of minutes, and switch it on the moment they land. If you want a physical SIM, you can still order one ahead from a site like SimOptions or Amazon and have it waiting at home or your hotel.
Prefer to buy in person? Major airports like JFK, LAX, and Miami have carrier kiosks and vending machines in the arrivals area, though prices there tend to run higher than online. You’ll also find prepaid SIMs at carrier stores (AT&T, T-Mobile, Verizon), big retailers like Best Buy, Walmart, and Target, and budget-friendly MVNOs like Mint Mobile and Cricket.
The 5 best prepaid SIM cards for the USA
America is a big place with lots to see and do. Buying a prepaid SIM card for the USA means that you can share every sight, sound, activity, and attraction with your friends. Looking for the best of the best? Here are my picks for the best prepaid SIM cards for the USA.
1. T-Mobile USA Canada Mexico
As one of the largest US carriers, T-Mobile runs one of the most extensive 5G networks in the country, which makes it a safe bet for coverage on the road. What’s more, it has one of the largest and most reliable networks in the country. No surprise then, that many Mexican and Canadian tourists interested in buying a prepaid SIM card in the USA turn to the T-Mobile USA Canada Mexico Card.
As the name suggests, the T-Mobile USA Canada Mexico Card provides users with unlimited talk and text capabilities when traveling through the USA, Canada, and Mexico. It also offers unlimited High speed 4G LTE data in the USA and up to 5GB of Data in Canada and Mexico. Though this SIM card does not allow for international calls outside of North America, it’s a great pick for tourists visiting from South of the Border or The Great White North.
2. Orange Holiday World
For travelers looking for something with more versatility than the T-Mobile USA Canada Mexico Card, there’s no better choice than the Orange Holiday World Card. Like the aforementioned T-Mobile card, it’s a 3-in-1 card, meaning it can accommodate phones that use standard, micro, or nano SIM cards. Unlike the T-Mobile card, though, it doesn’t just allow you to connect with users in the USA, Canada, and Mexico. It also connects you to virtually every country on Earth!
This kind of functionality comes with a significant price increase, but if you’re a serial traveler, it definitely pays off. The Orange Holiday World Card divides the planet into four different “zones,” each having its data limits. Notably, Zone 1 encompasses 66 countries including the USA, Mexico, Canada, and most of Europe and Asia. It tops out at 10GB, providing plenty of freedom for globetrotters.
3. Change eSIM from Airalo
For those less interested in buying a prepaid SIM card for the USA and more inclined towards eSIM, there’s the Change eSIM from Airalo. As with all of its eSIM offerings, the Change card is highly flexible, available in multiple variations to satisfy the diverse needs of many different kinds of travelers.
✈️ How I Fly for a Fraction of the Price (Even Business Class)
Airfare keeps climbing, but I almost never pay full price. Going.com emails me roundtrips to Europe for under $350. With Elite, you’ll even see business class to Europe for ~$1,700 (deals you won’t find on Google Flights).
Planning a big trip? Elite members save up to $2,000 on a single international business-class ticket. I’ve seen nonstop biz to Scotland for $1,250.

👉 Try Going Elite free →For example, if you’re only going to be visiting the United States for a short time, Airalo offers a 7-day Change card with up to 1GB of data. On the opposite end of the spectrum, there are multiple 30-day Change cards with data limits starting at 3GB and going as high as 10GB. Best of all, if you run out before your stay is over, Airalo makes it easy and affordable to “top up” by adding more days/gigs as needed.
4. Lycamobile Prepaid SIM
Widely considered one of the best MVNOs around, Lycamobile distinguishes itself not just for its exceptional value, but also by being one of just a few MVNOs that operate worldwide. Harnessing the power of T-Mobile’s network, the Lycamobile Prepaid SIM Card is a great low-cost option for bargain hunters.
Despite its budget price, the Lycamobile Prepaid SIM Card offers surprisingly robust connectivity. Talk, text, and data within the US are unlimited. International talk and text from the US to around 60 countries is also unlimited. It may not have the nearly global reach of Orange or Airalo, but it’s still powerful enough to keep you connected without breaking the bank.
5. Three PAYG Data Pack 10GB
UK-based company Three is famous for offering some of the best SIM cards for tourists in Europe. However, did you know that options like the Three PAYG Data Pack 10GB Card can also be useful for travelers interested in buying a prepaid SIM card for the USA? It’s true! Three’s coverage area is vast, encompassing not only most of Europe but also the United States and Puerto Rico, as well as parts of Asia and South America.
Of course, talk and text are more limited in the US than in most European countries. Nevertheless, incoming calls and texts from outside the US are free. That makes it ideal if you’re more concerned about receiving calls than making them. Likewise, if you’re a resident of Europe (or someone planning to travel there before or after visiting the US), the Three PAYG Data Pack 10GB Card will allow you to use the same SIM card in both regions. It’s a “two for the price of one” special.
- Heads-up: Three UK merged with Vodafone in 2024 to form VodafoneThree, so you may see the branding shifting. The PAYG data pack still works the same way for now
