Apple’s first eSIM-compatible iPhones were the iPhone XS, XS Max, and XR, released in 2018. If you have a model released after 2018, your iPhone is most likely eSIM compatible. In unique cases, this does not apply (e.g., iPhones in China).

If you want to check if your iPhone is compatible with eSIM manually:

• Open the Settings app, then TAP General, then TAP About.
• Scroll down to the “Carrier Lock” section.
• If your device is unlocked, it will show “No SIM restrictions.”
