How an eSIM actually works
🛒
Pick your plan
Choose a destination & data amount, grab a coupon, and buy in two taps — before you even pack.
📲
Scan the QR
A QR code lands in your inbox. Scan it in Settings and the eSIM installs in under a minute.
🛬
Land & connect
Flip it on when you arrive — you're online before baggage claim, home number still intact.
We run the speed tests so you don't have to
Every provider we recommend has been used on a real trip and benchmarked on local networks. These are our actual recorded download speeds — no estimates, no marketing numbers.
