eSIM Compatible Devices
Before buying a travel eSIM, confirm your phone supports it. Most smartphones from 2018 onward are eSIM-compatible, including iPhone XS and later, Google Pixel 3 and later, and recent Samsung Galaxy S, Note, Z Fold and Z Flip models.
A quick check: on iPhone go to Settings → General → About and look for an "Available SIM" or EID entry; on Android, search settings for "SIM" and look for "Add eSIM".
