Abstract: An eUICC is configured with one or more master delete keys each allowing an associated level of profile-deletion access for deleting one or more profiles from the eUICC, and the eUICC is configured to control profile-deletion access in accordance with the one or more delete keys. For instance, one delete key could allow deletion of any or all profiles on the eUICC including any operational profiles (e.g., MNO profiles) and any non-operational profiles. Whereas, another delete key could allow deletion of any or all operational profiles but not any non-operational profiles. Further, a blockchain protocol could be used to securely convey such a delete key from one party to another, helping to establish chain of custody of the delete key.
