1. A method for protecting a Type parameter of an electronic Subscriber Identity Module (eSIM) that is associated with a Mobile
Network Operator (MNO), the method comprising:
at an embedded Universal Integrated Circuit Card (eUICC):
receiving a request to store the eSIM within a memory that is accessible to the eUICC; and
in response to the request:
storing the eSIM into the memory,
parsing a file system of the eSIM to identify the Type parameter, and
updating a file access property of the Type parameter to prevent the Type parameter from being modified by the MNO.
