Before purchasing, make sure your device supports eSIM. Most phones released from 2018 onward are compatible. Check the list below or verify in your device settings.
iPhone: Go to Settings → General → About. Look for "eSIM" listed under Carrier. If you see it, your device is compatible.
Android: Go to Settings → Network & Internet → Mobile Network → SIMs. If you see an option to "Add eSIM" or "Download SIM", your device is compatible.
Note: Your device must be unlocked (not tied to a carrier) to use a third-party eSIM. Contact your carrier if you are unsure.
