Before you fly: your eSIM setup checklist.

A few quiet minutes at home can make your arrival a little easier.

Check the exact phone

eSIM support can differ by model, market, and carrier. Find your exact model and confirm that it is unlocked. A model family name alone is not a guarantee of compatibility.

Know when the clock starts

Before installing, read the plan’s activation policy. Some validity periods begin on installation; others begin when the eSIM first connects to a supported network. Save the provider’s installation guide where you can access it.

Set your data line carefully

Install with a reliable internet connection. At your destination, choose the travel profile for mobile data and follow its roaming settings. Disable automatic data switching if it might send data through your home carrier.
