Abstract
Techniques to manage notifications for state changes of eSIMs of a mobile device are described. Processing circuitry of the mobile device provides a command to the eUICC to delete an eSIM. The eUICC changes the state of the eSIM to a locked state and generates a notification of the forthcoming state change before completion of the transition to the deleted state. The processing circuitry sends the notification to a provisioning server and provides to the eUICC a response indicating successful delivery of the notification, and the eUICC subsequently transitions the eSIM to the deleted state. While the eSIM is in the locked state, applications and files of the eSIM can be unusable. In some embodiments, credentials of the eSIM can be reused to re-authenticate with a wireless network in order to deliver the notification to the provisioning server.
