My recommendation
Traveltomtom recommends a T-Mobile sim card for the USA if buying a prepaid sim card on arrival in the USA. T-Mobile has a very extensive 5G network all over the USA and for $50 USD you get unlimited data for 30 days, it is cheaper than AT&T and Verizon.
However, my recommendation is to order a sim card for traveling in the USA on the internet, not on arrival in the USA. The best USA sim card deals for tourists in 2025 can be found online. Why? It is simply easier and cheaper!
Unfortunately buying a prepaid sim card at any international airport in the USA is pretty much a disaster. Some airports don't even have sim card shops like at JFK Airport in New York or you can only find extremely overpriced sim card in a vending machine. Or what about a $82 USD sim card with 15 GB data at LAX?
Check out my guides for buying a sim card at Los Angeles, Newark, Miami and New York JFK.
So what does Traveltomtom recommends? The best, cheapest and easiest way to get a sim card with data for traveling to the USA in 2025 is an eSIM. You can already get a USA eSIM with 10 GB data for less than $25 USD.
Traveltomtom recommends ordering an eSIM for the USA via either SimOptions or Airalo.
There are also international physical prepaid sim cards with global network coverage for those that don't have an eSIM compatible phone. In the link you will find a review and comparison of the best international sim cards for traveling in 2025. You order one online before your trip to the US and get them delivered to your home address. Plug and Play!
Make sure your phone is unlocked, before buying a sim card for the USA. International, eSIMs and local prepaid sim cards for the USA only work in unlocked phones. If you are not sure if your phone is locked/unlocked ask your provider in your home country before your trip to the USA.
eSIM suggestions for traveling to the USA
The most convenient and easiest way to stay connected when traveling to the USA in 2025 is an eSIM. You can easily order them online within just a couple clicks.

Why buying a sim card in the USA
WiFi is everywhere these days, but when traveling in the USA, I am sure you want to be connected on the road as well and not only in your hotel room. Think about ordering a taxi through an app, finding nearby recommended restaurants, using Google Maps for directions and simply staying in touch or for checking social media apps and emails, being connected to your bank apps, etc.
Being connected the internet makes traveling so much easier and also safer! Don't get stuck somewhere because you don't have a data connection on your phone.
Buying a sim card for the USA is easy, it takes just a couple minutes and you are connected straight away, it is like plug and play. If you buy a sim card in a store in the USA you put it in your phone and it instantly works. However, you have to make sure your phone is unlocked if you want to use a prepaid sim card or an eSIM abroad.
Also don't rely on public WiFi. There is never a guarantee and internet speed varies often. Also keep in mind that surfing the web on public WiFi is through an UNSECURED connection. The use of a VPN is recommended in these cases.
Where to buy a USA sim card
International airport on arrival
Unlike any other country around the world it is NOT easy to find sim card shops or resellers at international arrivals in most of the airports in the USA. I still can't get my head around this! Like for real America? At Houston Airport the guy from the information desk was like, uh what... a prepaid sim card?
That said, I am determined to continue writing sim card guides for USA airports and already started with the Big Apple. Flying to New York? Check out my guides for buying a sim card at New York JFK Airport or buying a sim card at Newark Airport in New Jersey. The newest addition is my guide for buying a sim card at Miami Airport and my Los Angeles Airport sim card guide.
I have written uncountable sim card guides for international airports: Paris, London, Rome, Amsterdam, Barcelona, Madrid, Dublin, Johannesburg, Dubai, Riyadh, Tel Aviv, Istanbul, Cairo, Panama City, Bangkok, Bali, etc. At every international airport worldwide you will find sim card shops next to car rental companies and money exchangers, unfortunately not in the USA!
In the last years I landed in Los Angeles, Houston, Dallas/Forth Worth, New York JFK, Newark, Miami and there are literally no sim card shops or phone stores. Even more reasons for you to order a sim card for traveling to the USA on the internet.
Traveltomtom recommends ordering eSIMs via Airalo or SimOptions directly on the internet. SimOptions sells eSIMs as well as physical prepaid sim cards for the USA.
Official retail stores
The best place to buy a prepaid sim card for the USA is at an official retail store. The staff will give you the best advice on your needs and everything will be set up quickly and within just a couple minutes. You will walk out of the store with a working data connection on your phone. But I will later show you the prepaid sim card prices and you will see that eSIMs are much cheaper.
Best way to find the nearest phone shop is to go to Google Maps and type in for example: t-mobile. Google Maps suggest: 'T-Mobile (see locations)'. Click on it and find the nearest store. The bigger shopping malls in big cities mostly all have mobile phone provider stores.
Convenience stores
Yes, it is possible to buy USA tourist sim cards at convenience stores like 7-Eleven, CVS and of course at Walmart. They are mostly located behind the counter and gathering information about the data packages is a little challenging. Don’t expect the staff to know exactly what these tourist sim cards are about. It is not Traveltomtoms first recommendation to buy a sim card in the USA at a convenience or grocery store.
If you want to get connected and are in a hurry this is an option. You have to active these sim cards yourself by uploading your passport to the mentioned website on the sim card package.
Train stations
In the bigger cities like New York, Chicago, San Fransisco you can sometimes find sim card kiosks at the bigger train stations, like the above photo from Penn Station in New York. These sim card shops are resellers of MVNO sim cards. MVNO stands for Mobile Virtual Network Operator, a well known example is Lycamobile.
A Lycamobile sim card operates on the T-Mobile network in the USA and they sell the above data plans and packages including unlimited calls/text. These tourist sim cards are not cheap either and 7 GB data will already cost you $29 USD + tax.
Keep in mind that there are already eSIMs for the USA with 20 GB data for just $15 USD.
Online
As mentioned before an eSIM is the cheapest but also the easiest way to get data on your phone when traveling to the USA and Traveltomtom recommends ordering an eSIM for the USA via SimOptions, Jetpac, Holafly, Nomad, Airalo or one of the other reliable eSIM providers.
The downside of the sim cards for the USA you order online is that they are data-only. Sim cards you buy in a store in the USA including data, text and talk.
For more info check out Traveltomtom's comparison of the best eSIMs for the USA.
If your phone is not eSIM compatible you can also order physical prepaid sim cards on the internet via SimOptions. Check out my article about the best international sim cards for travelers in 2025, it has some really good alternatives and you can order directly online.
Mobile internet operators in the USA
In a country with more than 300 million people it is almost unimaginable that there are only 3 main mobile internet operators:
- T-Mobile
- AT&T
- Verizon
On top of that there are many MVNO's in the USA, so called Mobile Virtual Network Operators. What they basically do is use the network of one of the above main internet providers to offer their mobile services. Well known MVNO's in the USA are Sprint, Mint Mobile, Lycamobile and Boost. You can buy their sim cards in shops like Walmart, etc.
Verizon did not use to sell prepaid sim cards for tourists for many years, but the tables have turned and also Verizon now offers prepaid plans for tourists that can be bought in their Verizon stores.
Registration process
The registration process for prepaid sim cards in the USA is very standard. When buying a sim card you will need to bring your passport. In the store a copy of your passport or a photo will be taken and will be attached to your registration. Your new US sim card and number will be registered on your name and passport number.
To avoid this you can order a physical prepaid USA sim card online and get one delivered to your home address before your trip or order an eSIM for the USA. For these sim cards there is no form of ID verification needed, only your email address.
Prices prepaid sim cards USA in 2025
Prices below are in United States Dollar and info and prices are updated as per May 2025. eSIMs are available for an extra fee, but only in the official stores of T-Mobile, AT&T or Verizon.
You can not buy an eSIM on the international airports in the USA on arrival.
T-Mobile USA
Officially T-Mobile USA charges a $10 USD activation fee for a prepaid sim card for tourists in stores around the USA, but in most cases this activation fee is waived if you buy one of the above prepaid sim card plans. Ask for it in store!
T-Mobile offers 3 different prepaid sim card packages, see the above photo. All of the prepaid sim card deals come with UNLIMITED CALLING & TEXTING in the USA, the use of max data speed at 5G network and are valid for 1 month.
- 10 GB data = $40 USD
- Unlimited data + 3G hotspot = $50 USD
- Unlimited data + 10 GB 4G hotspot = $60 USD
The data is only for use in the USA, you pay $5 USD extra for max 5 GB data to use in Canada and/or Mexico. But when you travel to Mexico or Canada Traveltomtom recommends buying a sim card for Mexico and/or buying a sim card for Canada.
Also if you want an eSIM instead of a physical prepaid sim card that is no problem, just ask for it in the T-Mobile store.
T-Mobile offers eSIMs for tourists in their T-Mobile stores for an extra fee of $4.99 USD. So if you want to have a T-Mobile eSIM with unlimited data for the USA that will cost you a minimum of $55 USD and if you are unlucky they will also charge you the activation fee of $10 USD.
These are the latest T-Mobile prepaid sim card deals as per May 2025, for more info check the T-Mobile USA website.
AT&T USA
The activation fee for an AT&T USA prepaid sim is officially $15 USD, but also waived when in most cases when buying one of the above prepaid sim card plans. AT&T offers 2 prepaid USA sim card plans for tourists, don't get fooled by the sim card deals above. The first column is only if you pay for 12 months in advance, so not an option for tourists.
AT&T also has eSIMs for tourists available but they charge an extra fee of $4.99 USD.
Both prepaid sim card deals include unlimited calls/sms in the USA, max data speed on 5G and are valid for 1 month:
- Unlimited data at max 3 Mbps* (not 5G ready) = $50 USD
- Unlimited calls/sms and data = $65 USD
*First 30 GB per month on 3 Mbps then reduced data speed to 1.5 Mbps.
WOW! This is very basic data speed. Have you ever checked you home internet data speed? That is probably somewhere 50 - 100 Mbps or nowadays even up to 500 Mbps.
So AT&T offering a prepaid sim card with max 3 Mbps data speed is a JOKE!
Also be aware that the big advertising prices above are with AUTOPAY, basically auto renewal. Tourists do NOT want that so they pay more.
The $50 USD deal is only $50 USD if you renew automatically every month, so for tourists not applicable and without autopay is $65 USD.
Also it says unlimited calling, text and data in Mexico and Canada, but not on 5G speed. So there is another catch!
These are the latest AT&T prepaid sim card deals as per May 2025, check the AT&T USA website for more info. But as you can sense Traveltomtom is NOT a fan of AT&T prepaid sim cards. There are so many restrictions on these prepaid sim card deals.
When traveling to Canada and Mexico you might want to check Traveltomtom's article about buying an international sim card for North America.
Verizon
Verizon charges a staggering $35 USD activation fee for its prepaid sim cards, so therefore already Traveltomtom does not recommend buying a prepaid sim card in a Verizon store in the USA. However, on the Unlimited plans they wave away the activation fee.
All the prepaid plans from Verizon are valid for 1 month and are 5G ready. They also include unlimited calling and teting:
- 15 GB data = $45 USD
- Unlimited data + 5 GB data for hotspot = $60 USD
- Unlimited data + 25 GB data for hotspot = $70 USD
For more info check the Verizon website. Verizon offers physical prepaid sim cards as well as eSIMs for tourists.
When we look at the comparison of the USA prepaid sim cards the conclusion is simple: AT&T and Verizon are more expensive than T-Mobile. So based on the price I am definitely recommending a T-Mobile USA sim card over an AT&T or Verizon sim card.
Best 4G/5G network in the USA in 2025
Whether you are traveling to the USA as a tourist or for business the chances of not having a phone signal are very small. The network in the USA is countrywide pretty good and yes there is of course 5G in the United States. Prepaid sim cards that you buy in the USA support 5G, international sim cards and eSIMs for the USA do not always support 5G.
An exception are the Airalo eSIMs for the USA, these eSIMs are 5G ready as well as the Nomad USA eSIMs nowadays.
Let's compare the 4G/5G network of T-Mobile, Verizon and AT&T and find the best mobile data network in the USA in 2025.
AT&T 4G/5G network coverage map
T-Mobile 4G/5G network coverage map
Verizon 4G/5G network coverage map
Although the above mobile data network coverage maps are updated for 2025 they are not 100% accurate. However, they are a great reference to compare the 4G/5G networks of the mobile internet providers in the USA in 2025.
All the main mobile internet providers in the USA have an excellent 4G/5G mobile data network across the country and cover pretty much every tourist destination in the USA.
From the above USA mobile network coverage maps we can clearly see 2 things:
- AT&T and Verizon have better coverage in remote areas
- T-Mobile has the best 5G network
Click here for the official network coverage of T-Mobile and AT&T, according to their websites if you want more info.
After comparing the mobile data network coverage maps of Verizon, AT&T and T-Mobile Traveltomtom comes to the conclusion that all in all Verizon has the best mobile data network in the USA in 2025.
What is the best prepaid sim card for the USA in 2025
When comparing all the prepaid sim cards for the USA we can come to the very simple conclusion that T-Mobile is the best prepaid sim card in the USA in 2025. They offer the best prepaid sim card deals for tourists and also have the best 5G network in the country.
If we leave the activation fee out of the comparison and you want a 5G ready prepaid sim card with unlimited data for 1 month you pay the following in stores in the USA:
- Verizon: $70 USD
- AT&T: $65 USD
- T-Mobile: $50 USD
Reminder that for $26 USD you get an Airalo eSIMs for the USA with 10 GB data.
Therefore, Traveltomtom's conclusion that ordering a sim card on the internet is cheaper than buying a prepaid sim card in the USA on arrival.
eSIMs are the cheapest way to get internet on your phone and you can arrange everything online within just a couple minutes. Keep in mind that eSIMs are data only sim cards and calls are NOT supported.
Traveltomtom recommends ordering an eSIM for the USA via either SimOptions or Airalo. But check out Traveltomtom's guide with a comparison of the best eSIMs for the USA in 2025 for more info about USA eSIMs and also USA eSIMs from Jetpac, Holafly, Nomad and others eSIM providers.
If you want a sim card that also includes calling time and sms then you have to buy a prepaid sim card on arrival in the USA.
In that case Traveltomtom recommends a 5G ready sim card with unlimited data from T-Mobile. You might have to pay $10 activation fee but for $50 USD + taxes, you are sorted for the rest of your trip! If you want an eSIM instead of a physical prepaid sim card then add another $5 USD. You can only buy this sim card in a T-Mobile store in the USA. This sim card is valid for 1 month.
When I took a road trip from Las Vegas to New York and I bought a T-Mobile sim card in Las Vegas and traveled around the US for about 3 weeks. I never had a problem connecting and the T-Mobile 5G network experience was amazingly FAST! Even in some of the National Parks that I visited there was either a 5G or 4G/LTE signal: Zion in Utah, Grand Canyon in Arizona, Shenandoah in Virginia, everywhere I had an excellent signal throughout my journey with a T-Mobile sim card.
However, on my recent trip to the USA I ordered an eSIM for the USA on the internet. It was a short trip and I only needed 5 GB data anyway. eSIMs are simply so easy and convenient to order and use.
At Times Square New York you will find a T-Mobile store, a AT&T store and a Verizon store within 300 meter from each other. You can walk in, buy a prepaid sim card and you are connected within 5 minutes, but yeah it will cost some time and energy to get connected if you decide to buy a prepaid sim card in the USA rather than order a sim card for the USA on the internet.
If that sounds like too much hassle then order an eSIM for the USA. Another reminder that eSIMs for the USA are actually CHEAPER! Through Airalo you can find eSIMs with 3 GB data for just $11 USD. SimOptions offers a USA eSIM plan with 10 GB for $24.90 USD and then there is also Holafly, Nomad, Jetpac and other eSIM providers.
Or if you want a physical sim card then check out my article about the best prepaid global sim cards in 2025 including free roaming in the USA.
Order a physical prepaid sim card for the USA online
You can only buy the above mentioned USA prepaid sim cards from T-Mobile, Verizon and AT&T on arrival in the USA. But if you rather arrive prepared you can order a sim card on the internet. If your phone is not eSIM compatible then look into the following.
Arrive prepared in USA with an international prepaid sim card. You order them online and a physical prepaid sim card will be delivered to your home address. You put this sim card in your phone and it automatically connects to an available network upon arrival in the US, basically when the plane lands you are instantly online.
SimOptions is the only sim card provider that sells physical prepaid sim cards for the United States:
- 10 GB data valid in 56 countries for 30 days = $24.90 USD
- 10 GB data valid in 124 countries for 30 days = $49.90 USD

Comparing the above international prepaid sim cards for the USA then personally I would recommend the sim card with 10 GB data for $24.90 USD. But you have seen that eSIMs were cheaper.
