Two things must be true before you buy: your phone must support eSIM, and it must be carrier-unlocked.
The 30-second check
iPhone: Settings → General → About → scroll to the bottom. If you see "Available SIM" or an EID number, you have eSIM.
Android: Settings → Network & Internet → SIMs, or search "SIM" in Settings. If you can add an eSIM or download a SIM, you have eSIM.
Any device: dial *#06#. If an EID appears, your phone supports eSIM.
Supported devices
- iPhone XS, XR and every iPhone since
- Google Pixel 3 and later
- Samsung Galaxy S20 and later, Z Fold and Z Flip series, most recent A-series
- Recent iPad models, Apple Watch Cellular, and many other Android flagships
Not supported
- Phones locked to a carrier — ask your carrier to unlock the device first
- Most models sold in mainland China and Hong Kong, where eSIM is disabled
- Older phones with no EID
Important
If your phone is not compatible, please do not purchase. An eSIM cannot be installed on a device that does not support it, and once a profile has been activated we cannot refund it. If you are unsure, message us at support@cometsim.com before you buy and we will check your exact model for you.
