# Can I install an eSIM that has already been installed on another device?

No. An eSIM that has already been activated on a device cannot be reactivated or transferred to another device.

If you want to use Kurosim on a different device, you’ll need to purchase a new eSIM for that device. This is because each eSIM can only be activated on one device.
