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 Los Angeles and wondering if you can buy a prepaid SIM card at Los Angeles International Airport LAX on arrival? The short answer is yes, you can buy a tourist SIM card at LAX Airport, but I do not recommend it.

There is only one place to buy a SIM card at LAX Airport and they only sell physical prepaid SIM cards, no eSIMs. The cheapest prepaid SIM card at Los Angeles Airport starts at ~$82 USD for just 10 GB data, which makes it one of the most expensive tourist SIM cards I have seen at an airport in the USA. 

In this complete guide I will show you exactly where to buy a SIM card at Los Angeles Airport, the latest LAX Airport SIM card prices for 2026, why buying a SIM card on arrival is not good value, and what the best alternatives are for staying connected in Los Angeles.
