Planning a trip to the USA in 2026 and looking for the best eSIM for USA? You are in the right place.

Local SIM cards are relatively expensive, and not all unlimited data eSIM plans are actually unlimited. Prices, data limits and reliability vary a lot between providers.

I have traveled to more than 170 countries and over 35 US states, testing SIM cards and eSIMs all over the world. In this guide I compare the best eSIMs for the USA based on real data, pricing, and my own experience using them on the road.

If you just want a quick answer: there is no single best eSIM for everyone. It depends on the length of your trip and your data usage. But my top pick right now and the eSIM I used on my recent trip to the USA: Sim Local.

Planning your trip to the USA in 2026 and wondering what is the best prepaid SIM card? Staying connected in the United States can be expensive compared to what you are used to when traveling in Europe or Asia.

I have traveled to the USA more times than I can count and so far visited more than 35 states. From road trips through the Midwest, California and Arizona, snowboarding in Colorado and Utah to exploring cities like New York, Miami and Chicago, I have tested pretty much every way of staying connected in the US.

Here is the truth: buying a prepaid SIM card in the USA is not as straightforward as you might think.

Planning a trip to Miami and wondering if you can buy a prepaid SIM card at Miami International Airport on arrival? The short answer is yes, you can buy a SIM card at Miami Airport, but it is not as convenient as you might expect and it is definitely not the best-value option for most travelers.

There are no SIM card shops in the international arrivals hall at Miami Airport. If you want to buy a tourist SIM card after landing, you first need to go one floor up to the departures level. There you can find two places that sell prepaid SIM cards for tourists: Communitel and the Currency Exchange.

The cheapest prepaid SIM card at Miami Airport costs $37 USD for just 4 GB data. The other option is a Lycamobile SIM card with 12 GB data for $70 USD. These airport SIM card prices are expensive compared to USA eSIMs and local prepaid SIM card deals in Miami city.

In this complete guide I will show you exactly where to buy a SIM card at Miami Airport, the latest Miami Airport SIM card prices for 2026, which tourist SIM card is the best option at the airport, why I do not really recommend buying a SIM card at MIA Airport, and what better alternatives you have for staying connected in Miami.
