Abstract:
A device hosting a universal integrated circuit card (UICC or eUICC) initiates an electronic subscriber identity module (eSIM) installation flow with an SIM server. The purpose of the eSIM installation flow is to perform a profile provisioning action. The device and, for example, the eUICC preserve state information related to the eSIM installation flow. The eSIM installation flow includes generation of a one-time public key at the eUICC. In some instances, the eSIM installation flow may be interrupted by an error event before successful installation of the eSIM in the eUICC. A subsequent renewed installation attempt is locally initiated and completed without assistance of the eSIM server. In some embodiments, the recovery and subsequent successful eSIM installation make use of the state information preserved during the earlier eSIM installation flow.
