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.
