Abstract: This application describes cellular service transfer mechanisms that can be used to convert cellular service credentials on a physical SIM (pSIM) card included in a wireless device to a newly downloaded electronic SIM (eSIM) on an embedded universal integrated circuit card (eUICC) of the wireless device. Transfer of the credentials for cellular service access can occur locally within the wireless device with authorization to transfer obtained from a mobile network operator (MNO) entitlement server associated with the pSIM. The new eSIM corresponding to the previously used pSIM can be downloaded to the eUICC from a provisioning server of the MNO.
