At a glance

Best overall

Mint Mobile is one of the best MVNO carriers today and uses T-Mobile's 4G LTE and 5G network, making it a great prepaid SIM card to get if you plan on staying in the U.S. for at least three months. As we found in our Mint Mobile review, Mint's 5G connection is strong, and its phone compatibility is one of the best in the country.

With Mint, you need to purchase at least three months of service upfront. After that, the best deals are offered when you sign up for six months or 12. For three months on the unlimited plan, you'll pay $90 and get unlimited talk, text, and data, 10GB of mobile hotspot, and free calls to Mexico and Canada. Calling to other international locations is available at a per-minute rate but if you use an app to call your friends such as WhatsApp or Line, you'll only need data.

Joining Mint Mobile is easy, and you can even sign up for a trial online to get a free Mint Mobile SIM card. It's especially easy if your phone is eligible for an eSIM since you can then activate the SIM straight from your phone and later continue your service if you like it. You can also get a Mint SIM card from Target, Best Buy, Walmart, or Amazon.

Best for short stays

Ultra Mobile is an MVNO on T-Mobile's network, meaning that you'll get great T-Mobile coverage at a lower price. Our Ultra Mobile review showed strong coverage and speeds. Though Ultra Mobile offers its own set of prepaid plans, the Ultra Mobile 3GB plan is a perfect fit for anyone visiting the U.S. for a month or less.

This is a more traditional SIM and after 30 days, the plan will expire, making it great for users who just wanted simple talk and text to a wide range of destinations and don't need a lot of data on their travels. For $19 with the SIM kit included, you'll get unlimited talk and text to over 90 countries worldwide, plus free Wi-Fi calling and up to 4GB of 5G/LTE data, meaning you should have no issue reaching friends and family back home.

Best value

Lycamobile is unique because it's a global MVNO, and in the U.S., it's an MVNO on T-Mobile's network. To check whether your phone is compatible, the easiest thing to do is type in your IMEI number on Lycamobile's website, but most GSM unlocked devices should work.

Lycamobile offers several plans to pick from and really caters to those who need unlimited nationwide talk and text and international calling and texting to 85+ countries. Each plan includes these features at no additional charge, making this the perfect plan if you're someone who wants to be able to call abroad whenever you want.

When it comes to data, you have multiple options starting at just 250MB and going up to 60GB. The cheapest 250MB plan costs $15, while the top unlimited data plan costs $59. The 2GB plan is only available to new customers so if you're already signed up, this plan will come with 1GB of data. Each plan includes slightly different bonus features, so you'll have to pick what makes the most sense for you.

Fortunately, Lycamobile SIM cards are pretty easy to get a hold of. They're sold online on Lycamobile's website and Amazon, but you'll also find Lycamobile SIM cards in several retailers, including 7-Eleven, pharmacies, local convenience stores, etc. When in doubt, you can also use the online store locator to find the nearest retailer near you.

Best non-MVNO

Known for its great coverage, AT&T is also an excellent carrier to consider getting a SIM card from when visiting the U.S. and one of the best prepaid phone plans. It tends to have better coverage in rural areas than other carriers, so it's also a great option if you plan to be on the road a lot. For $30 (plus taxes and fees), AT&T Prepaid will get you 5GB of high-speed data, which is then throttled to 128Kbps. As always, you should check your device's compatibility with AT&T online before signing up.

On this plan, you're able to use your mobile hotspot, and you can text to more than 230 countries. You'll also be able to talk, text, and use data in Mexico and Canada (though data speeds may be slow). And if you think you'll need more than 5GB of data, you can always upgrade to a 15GB prepaid plan for $40, which is a great deal and definitely worth considering.

Best prepaid data plan

T-Mobile not only offers some of the best cell phone plans you could get today, but it also has an excellent prepaid option that will suit most travelers and tourists needs when visiting the U.S. Because T-Mobile's network has improved vastly over the past few years and its 5G network has some of the most expansive coverage and fastest speeds in the nation, you'll likely get excellent service with T-Mobile when traveling to major cities during your stay.

There are four T-Mobile prepaid plans from which to choose, though the ideal plan for most visitors will be T-Mobile's 10GB prepaid plan for $40 per month. This plan includes unlimited domestic talk and text, up to 10GB of high-speed data, free mobile hotspot data, and a music unlimited feature so that any music you stream won't eat up your data. If you want to add international calling, you can do so for $15 extra, or if you're traveling to Mexico or Canada for a few days, you can add talk, text, and 5GB of data to use over there for an extra $5.

Best data-only plan

If you don't think you'll need minutes during your stay in the U.S. and really just want data, you could consider a data-only plan from Cricket Wireless, which is an MVNO on AT&T's network. For $35, you'll get 20GB to use during the month, or for $55, you'll get 100GB.

Again, this plan doesn't come with any minutes, so you'll have to be sure you're fine using apps like WhatsApp, Facebook Messenger, or Skype to connect with family or friends. It does come with text and picture messages across the U.S., as well as usage in Mexico and Canada if you plan on visiting those countries as well. It's the perfect plan for anyone who will be spending lots of time on the road and wants to be able to stream, download, and do some high-speed browsing.

You can get a Cricket SIM card by going into a Cricket Wireless authorized retailer, which you can locate with Cricket's online store locator. Other popular retailers such as Amazon, Target, Best Buy, and Walmart will also sell Universal SIM card activation kits for Cricket Wireless. The good news is that if you do end up wanting minutes, you can always switch to another one of Cricket's plans with the same SIM card.

FAQ

Which prepaid SIM card is best for you?

You really can't go wrong with a prepaid SIM card on T-Mobile or AT&T's network while visiting the U.S., and the right fit for you depends on the length of your stay and whether you need features like being able to call back home. If you're traveling for only three weeks or less, the Ultra Mobile Tourist plan is the best choice and offers just enough talk, text, and data to stay connected.

On the other hand, if you'll be in the U.S. for a few months, Mint Mobile will give you the best multiple-month value. And if you're somewhere in between, a prepaid plan from either T-Mobile or AT&T is easy, reliable, and guaranteed to give you great coverage.
