Abstract
The present invention relates to a system constituted by a mobile network operator (MNO), a subscription manager (SM), and an embedded UICC (eUICC), wherein the MNO system or the SM stores an eUICC certificate that can verify the identity of the eUICC, transfers the eUICC certificate to the MNO system or the SM in a provisioning or MNO changing process, verifies the identity of a corresponding eUICC using the received eUICC certificate, and encrypts and transfers a profile to the eUICC only if the verification is successful so that the eUICC may be verified during the provisioning or MNO changing processes.
