Abstract

Apparatus and methods for managing and sharing data across multiple access control clients in devices. In one embodiment, the access control clients comprise electronic Subscriber Identity Modules (eSIMs) disposed on a embedded Universal Integrated Circuit Card (eUICC). Each eSIM contains its own data. An Advanced Subscriber Identity Toolkit application maintained within the eUICC facilitates managing and sharing multiple eSIMs' data for various purposes such as sharing phonebook contacts or facilitating automatic switch-over between the multiple eSIMs (such as based on user context).
