iOS 16 allows you to use Bluetooth to transfer an eSIM to a new iPhone

Because iOS 16 is currently in testing, carrier support for this new feature is likely to be limited for the time being, so we won’t know how many carriers and countries will fully support it until iOS 16 is released this autumn. iOS 16 is presently in developer preview, and it contains widget-enabled lock screens, iMessage edit and undo send capability, an iCloud shared photo library, and much more.
