Why Use an eSIM for Your USA Trip?

The United States is a vast country — from New York City skyscrapers to the national parks of Utah, staying connected is essential. An eSIM lets you activate a US data plan before you even board your flight, so you land ready to navigate, translate, and share.

No more hunting for a T-Mobile store or paying extortionate hotel Wi-Fi fees. Just scan, activate, and go.

Most modern smartphones support eSIM, including:

iPhone XS and later (iPhone 14 and later are eSIM-only in the US)
Samsung Galaxy S20 and later
Google Pixel 3 and later
Most flagship Android phones from 2020 onwards

Check under Settings → General → About on iPhone, or Settings → Connections → SIM Manager on Android to confirm eSIM support.
