Abstract
Apparatus and methods for storing and controlling access control clients. In one embodiment, transmitting and receiving devices ensure that only one copy of an eSIM is active at any time. Specifically, each transferred eSIM is encrypted for the destination device; the eSIM from the source device is deleted, deactivated, or otherwise rendered unusable. Various aspects of network infrastructure are also described, including electronic Universal Integrated Circuit Card (eUICC) appliances, and mobile devices. Various scenarios for transfer of eSIMs are also disclosed.
