Best Prepaid SIM Cards for USA Travel in 2025
Planning a trip to the USA and want to stay connected hassle-free? Navigating the prepaid SIM card market in the USA might seem a bit complex, unlike the more advanced options in Europe and other parts of the world. However, don't worry; it's not as complicated as it appears, though it can be on the pricey side! Purchasing a SIM card for the USA is the optimal way to access data on your phone without racking up exorbitant roaming charges.
This comprehensive guide covers everything you need to know about obtaining a USA SIM card: why to purchase one, the best 4G/5G network options, our personal recommendations, experiences buying a SIM card in the USA, the finest eSIM cards available for the USA, and insights into international SIM cards for use in the USA.
Here’s a rundown of frequently asked questions and the variations in USA prepaid SIM card plans that you can plug into your smartphone and avoid international roaming charges.
What is a US SIM card?
A prepaid US SIM card is an easy, affordable and convenient option to use your phone in the USA. Instead of paying for international roaming charges or opting for costly local prepaid smartphone plans, you can simply purchase a prepaid SIM card before your trip.
If they're US-based SIM cards from US carriers such as T-Mobile, AT&T like the ones we sell at SimCorner, they'll get assigned a USA phone number. If they're not US-based SIM cards, they might be roaming sim cards. They will still work in the USA but be assigned a UK number or Estonian number, etc.
At SimCorner, we recommend choosing a US-based SIM card from carriers like T-Mobile or AT&T for the best value, which includes unlimited calls, SMS, and data allowance, along with better coverage and data speeds.
Why Opt for a USA Prepaid SIM Card or USA eSIM for your Travel?
With the convenience of Wi-Fi everywhere, you might wonder why a prepaid SIM card or eSIM card is necessary. The answer is simple: to ensure you're connected on the go, beyond the confines of your hotel room. Whether you're hailing a ride, exploring local eateries, navigating with Google Maps, staying in touch with loved ones, managing your finances through banking apps, or even just scrolling through social media, a reliable data connection is indispensable. Moreover, relying solely on public Wi-Fi can be risky due to variable speeds and potential security vulnerabilities.
Purchasing a prepaid SIM card for the USA is incredibly straightforward, taking just a few minutes to activate. It's essentially a plug-and-play experience – insert the eSIM card into your unlocked device, and you're instantly connected. However, ensure your phone is compatible and unlocked to use either a prepaid physical SIM card or an eSIM card.
Where to Purchase a USA SIM Card
Arriving at international airports might not yield SIM card shops as easily as in other countries. Official retail stores, while trustworthy, sometimes neglect phone compatibility checks. Popular convenience stores like 7Eleven, CVS, and Walmart do offer options, albeit with limited staff knowledge. Alternatively, major train stations in cities like New York sometimes house SIM card kiosks.
If convenience is paramount, online shopping for e-SIM cards or physical prepaid SIM cards is your best bet. However, be cautious of third-party networks – opt for options from T-Mobile, AT&T, or Verizon to ensure optimal coverage and speed.
Why should you buy a USA SIM card in Canada before you fly?

Our Top Recommendation: T-Mobile's USA SIM Card
Our extensive experience helping customers for over a decade leads us to recommend T-Mobile Unlimited Data card for the USA. With a robust 5G/4G network spanning the country, T-Mobile offers unlimited data for 30 days, making it a more economical option than AT&T or Verizon. This is a great all-rounder option for Canadian travellers who want Unlimited data at a great value.
Will my phone work in the US?
Most Canadian citizens flying to the States should remember that network providers in the US use different frequencies to those back home. If you want to use your phone over there, you'll need to double-check what frequencies it supports before deciding to purchase a SIM card for the USA. You can go to a mobile phone shop, or you can use the contact us link above to get in touch with us, and we would be able to check if your phone is compatible with the prepaid sim cards from T-Mobile or ATT.
You will also need to make sure your phone is unlocked. If your phone is on a post-paid plan or contract with your local carrier it doesn't mean your phone is locked. If you are unsure, please check with your current service provider.
Best USA Mobile Internet Operators in the USA
How do you pick the one prepaid USA sim card for your travel needs? While there are international sim cards available where they work in Europe and USA, we advise sticking to actual USA sim card options for the best coverage and speed within the USA. It's crucial also to ensure if you are going with eSIM option that your phone supports eSIM functionality before making a purchase.
Despite the USA's vast population, only three main mobile internet operators reign supreme: T-Mobile, AT&T, and Verizon.
T-Mobile - One of the most competitive cell phone carriers in the US, T-Mobile is an excellent choice for picking cheaper SIM options with good coverage across the vast amount of mainland America and Hawaii. They also offer the best prepaid sim bundles that are great value for money.
Verizon - America's best carrier for coverage is Verizon, which provides excellent coverage and fast data plans. Verizon's 4G LTE network currently has the best nationwide coverage in USA compared to any local carrier, which is great if you are driving around town.
AT&T -The last big mobile carrier, AT&T is a popular choice as it offers the most coverage across the USA and its territories. But recently, Android phones not purchased directly from AT&T, are having calling issues on the AT&T network (data is working fine). If you need calling service we recommend that you purchase the T-Mobile or Verizon, otherwise you will run into issues whilst over there.
Similar to here in Canada, the US also offers a range of smaller phone carriers such as LycaMobile or Lebara. While these are still local SIM cards, they run on one of the main phone networks noted above but offer their own services. These include Metro and Ultra Mobile, which both run on the T-Mobile network.
Although these smaller phone providers use T-Mobile's network, they have some limitations in order to reduce prices. They may not span the whole network, and coverage may be limited in many places. This would mean you would not get the best coverage, as compared to other AT&T or T-mobile SIM card options. In addition, Metro also has strict limitations on video streaming in its data.
This is why we recommend choosing a sim card from one of the two main carriers in America when buying USA SIM cards, as they offer coverage in most of the main cities and/or tourist areas.
