Supporting SIM toolkit applications in embedded UICCs

A method for routing commands to electronic Subscriber Identity Modules (eSIMs) managed by an embedded Universal Integrated Circuit Card (eUICC) included in a mobile device, comprising:

• at the eUICC within the mobile device:
• receiving a request to provide an indication of the eSIMs that are managed by the eUICC;
• providing the indication, wherein the indication includes unique identifiers for each of the eSIMs that are managed by the eUICC;
• receiving, from a requesting entity, a request to generate instructions for carrying out a particular action associated with a Mobile Network Operator (MNO), wherein the request includes a unique identifier of a specific eSIM managed by the eUICC to which the request is directed;
• directing the request to the specific eSIM;
• receiving, from the specific eSIM, a set of instructions for carrying out the particular action;
• and
• providing the instructions to the requesting entity.

A mobile device, comprising:

• an embedded Universal Integrated Circuit Card (eUICC);
• a baseband component;
• a processor;
• and
• at least one memory configured to store instructions that, when executed by the processor, cause the mobile device to carry out steps that include:
• exchanging capability information between the eUICC and the baseband component, wherein the capability information indicates that each of the eUICC and the baseband component are capable of simultaneously managing two or more electronic subscriber identity modules (eSIMs);
• and
• updating a configuration of both the eUICC and the baseband component to cause each command issued between the eUICC and the baseband component to include a unique identifier of a particular eSIM to which the command is directed.

A non-transitory computer readable storage medium configured to store instructions that, when executed by a processor included in a mobile device, cause the mobile device to route commands to specific electronic Subscriber Identity Modules (eSIMs) managed by an embedded Universal Integrated Circuit Card (eUICC) included in the mobile device, by carrying out steps that include:

• issuing, to the eUICC, a request for an indication of eSIMs that are managed by the eUICC;
• receiving the indication from the eUICC, wherein the indication includes, for each eSIM managed by the eUICC, a unique identifier associated with the eSIM;
• receiving a request to carry out an action associated with a Mobile Network Operator (MNO), wherein the request is directed to a specific eSIM of the eSIMs managed by the eUICC;
• generating a command associated with the action, wherein the command includes the unique identifier associated with the specific eSIM and is routed to the eUICC;
• and
• in response to receiving, from the specific eSIM, instructions for carrying out the action:
• executing the instructions to cause the action to be carried out.
