Abstract
Embodiments are described for identifying and accessing an electronic subscriber identity module (eSIM) and associated content of the eSIM in a multiple eSIM configuration. An embedded Universal Integrated Circuit Card (eUICC) can include multiple eSIMs, where each eSIM can include its own file structures and applications. Some embodiments include a processor of a mobile device transmitting a special command to the eUICC, including an identification that uniquely identifies an eSIM in the eUICC. After selecting the eSIM, the processor can access file structures and applications of the selected eSIM. The processor can then use existing commands to access content in the selected eSIM. The special command can direct the eUICC to activate or deactivate content associated with the selected eSIM. Other embodiments include an eUICC platform operating system interacting with eSIMs associated with logical channels to facilitate identification and access to file structures and applications of the eSIMs.
