Best overall

Arguably among the best MVNO carriers available today, Mint Mobile uses T-Mobile's (its parent company) 4G LTE and 5G network infrastructure. This makes it an incredible prepaid SIM card if you plan on staying in the U.S. for at least three months. Our Mint Mobile review highlighted the service provider's strong 5G connectivity and phone compatibility, which is among the country's best.

With Mint Mobile, you need to purchase at least three months of service upfront. After that, the best deals are available when you sign up for either six or 12 months. For three months on the unlimited plan, you'll have to pay $90 and enjoy all sorts of goodies, such as unlimited talk, text, and data, 10GB of mobile hotspot data, and even free calls to Mexico and Canada. Mint Mobile has also removed data cap from its unlimited plan, making it better than ever. For the base 5GB plan, you would be paying $15 for each of the three months and $45 as one-time advance payment. Calling other international locations is available at a per-minute rate, but if you use an app (e.g., WhatsApp, Line) to call your friends, you'll only need data.

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

Best for short stays

Ultra Mobile is a Mobile Virtual Network Operator (MVNO) utilizing T-Mobile's network, which means that you'll get great T-Mobile coverage at a lower price. Our Ultra Mobile review showed strong coverage and speeds. The Ultra Mobile 3GB plan is ideal if you only intend to visit the United States for a month or less. But if things change and you end up staying longer, you can enjoy tempting discounts too.

With the 3GB plan, you get a regular SIM and after 30 days, the plan's validity will end, which makes it great for users who just want simple talk and text to a wide range of destinations without relying too much on data during their trip. For a monthly cost of $19 (taxes and fees not included), you get a SIM kit offering unlimited talk and text to more than 90 countries worldwide, plus free Wi-Fi calling and up to 3GB of 5G/4G LTE data, so you should have no issues staying connected with friends and family. The plan also offers a monthly $1.50 international calling credit and a one-time $5 international roaming credit.

What makes Lycamobile unique is the fact that it's a global MVNO, and in the U.S., it's an MVNO using T-Mobile's network. To see if your phone is compatible, all you have to do is enter the IMEI number on Lycamobile's website, but most unlocked GSM devices should work without any issues.

Lycamobile offers multiple plans to choose from, although it mainly serves those who need unlimited text and talk. The plans also include international calling and texting to more than 100 countries, and you can enjoy these features at no additional cost. With these perks, it's difficult not to lean towards Lycamobile.

When it comes to data, you have several options, starting at just 500MB and going up to 60GB. The cheapest 500MB plan costs $15 per month, while the unlimited plan with 60GB of data can be availed at an effective price of $45 per month if you pay for three months. The bonus feature changes slightly with each plan, so remember to take the time to choose the right one for you.

You can effortlessly obtain one of Lycamobile's SIM cards. You can buy one on Amazon or via the carrier's official website, but if you prefer, you can get them at pharmacies, 7-Eleven stores, and local convenience stores too. If you have questions, you can also use the online store locator to find the nearest retailer.

Best non-MVNO

AT&T is one of the best choices for getting a SIM card when visiting the U.S. The carrier has fantastic coverage and offers one of the best prepaid phone plans. It also tends to have a bit better coverage in rural areas than other carriers, so it's a great option if you plan to be on the road a lot. For $30 a month (taxes and fees extra), AT&T Prepaid offers 5GB of high-speed data, which is then throttled to 128Kbps after you've used the data allotment. As always, you should check your phone's compatibility with AT&T online before you sign up for it.

This plan offers texting to over 230 countries and shared mobile hotspot. If 5GB is not enough for you, you can always switch to the 30GB prepaid plan and pay only $45 per month. The plan also includes data usage in/between the United States, Mexico, and Canada. Also, the 5GB plan's rollover data feature means your unused data gets added to the next month's data allotment.

Best prepaid data plan

Not only does it offer some of the best cell phone plans you can get, but also T-Mobile has solid prepaid services suitable for most tourists and travelers who visit the country. The T-Mobile network has improved vastly over the past few years, with the carrier's 5G network having some of the best general coverage and fastest speeds in the nation. As a result, you'll get excellent service when traveling to major cities during your stay.

There are four T-Mobile prepaid plans to pick from, but the ideal plan for most visitors will be T-Mobile's 10GB prepaid plan, which costs $40 per month before taxes and fees. It has unlimited domestic talk and text, up to 10GB of high-speed data, shared mobile hotspot, and a nifty 'Music Unlimited' feature, meaning that you won't have to worry about data usage when you stream music. If you want to add international calling, you can for an extra $15 per month, or if you're traveling to Mexico or Canada for a few days, you can add talk, text, and 5GB of data to use in those countries for an added $5 per month.

Best data-only plan

If you don't think you'll need talk time minutes during your United States stay and only require data, you could consider a data-only plan from Cricket Wireless, an MVNO that uses (and is owned by) AT&T. For $35, you'll get 20GB of data for a whole month. If you need more data, you can go for the $55 plan with 100GB of data for a month. You can even get 150GB of data for $90 per month if you need even more.

Again, this plan doesn't have any talk time minutes, so you'll have to ensure you're fine using messaging apps like WhatsApp, Facebook Messenger, or Skype to connect with family or friends back home. It also includes text and picture messages across the U.S. and usage in Mexico and Canada if you plan on visiting those countries. The plan is great if you'll be streaming, downloading, and doing some high-speed browsing while on those long road trips.

Walking into a Cricket Wireless store and getting a SIM card instantly is quite possible, and the online store locator tool can help you find the nearest store. Popular retailers such as Amazon, Target, Best Buy, and Walmart also sell Universal SIM card activation kits for Cricket Wireless. The good news is that if you want minutes, you can always switch to another carrier's plan using the same SIM card.

How to choose

Know your requirements before getting a prepaid SIM card

Why you can trust Android Central Our expert reviewers spend hours testing and comparing products and services so you can choose the best for you. Find out more about how we test.

Thanks to constantly improving network infrastructure and a diverse range of plans, you can't go wrong with any wireless service provider these days, be it a regular carrier or an MVNO. Getting the right prepaid SIM card primarily depends on your use. If you'll only be staying for a few days, we suggest Ultra Mobile's 3GB plan. The plan offers Wi-Fi calling, unlimited talk and text, and monthly international calling credit.

Conversely, if you'll be staying for a few months, any of Mint Mobile's plans will be ideal. Owned by T-Mobile, it offers excellent network coverage and benefits such as mobile hotspot functionality and free calls to Mexico and Canada. You can even avail yourself of a free trial, and if you like the service, sign up for multiple months for great savings.

AT&T offers excellent coverage and is ideal if you travel a lot. Although you'll pay more, you'll get good speed and coverage.

Should you get an international add-on with your current service provider?

Almost every mobile operator in the world has partnerships with service providers in other countries. This option looks tempting because it simplifies things: you only deal with your current service provider, not the one you're unfamiliar with. You can activate a suitable international add-on on your existing SIM card before coming to the country and even have service when waiting for a connecting flight. However, be aware that these add-ons are often expensive, and coverage might not be as good as it would be with a carrier in the United States.

How about eSIM platforms?

If your smartphone supports eSIM functionality, you can go for one of the many eSIM apps/platforms to quickly buy and activate a wireless service plan. This will save you the hassle of ordering a physical SIM card and waiting for it to arrive so you can put it in your phone and start using it.

One such platform is Airalo, which lets you get an eSIM with as little as 1GB of data and a one-week validity. T-Mobile also has an app (available for iOS) that allows you to order and activate your eSIM with little to no effort.
