Compatibility
How do I know if my phone is compatible with an eSIM?
Two things matter: your phone needs eSIM hardware, and it must be carrier-unlocked. Most flagship phones from 2019 onward tick both boxes.
Check for eSIM hardware
- iPhone: Settings → General → About — look for an EID number.
- Android: Settings → About phone → look for an EID, or Settings → Connections → SIM manager → Add eSIM.

Make sure it's unlocked
Carrier-locked phones can't add a third-party eSIM. If you bought the phone outright or finished your contract, it's typically unlocked — your carrier can confirm.
