Abstract: Embodiments are described herein for transferring a subscriber identity module (SIM) or electronic SIM (eSIM) profile securely from a source device to a target device with verifiable signatures generated by secure hardware elements of the source device contingent on receipt of a secure intent gesture. Trustworthiness of the profile transfer is based on a mobile network operator (MNO) entitlement server releasing a transfer token after verification of a message signed by an embedded universal integrated circuit card (eUICC) of the source device. The eUICC signs the message only after verifying a message from a secure enclave processor (SEP) of the source device that signs the message based on receipt of the secure intent gesture via a secure interface. To validate communication between the SEP and the eUICC, an asymmetric cryptographic key pair generated by the SEP is bound to a unique eUICC identifier (EID) value of the eUICC.

Abstract: This Application sets forth techniques for managing subscriber identity module (SIM) toolkit (STK) scheduling for multiple enabled electronic subscriber identity module (eSIM) profiles on an embedded universal integrated circuit card (eUICC) of a wireless device, including managing multiple STK sessions at a baseband processor external to the eUICC of the wireless device. To forestall STK communication for different eSIMs from interfering with execution of processes associated with the eSIMs, a baseband processor can schedule STK sessions to avoid overlap and reduce opportunities for errors in handling eSIM processes. The baseband processor can prioritize whether to queue commands for a second STK session for a second eSIM until a first STK session for a first eSIM ends or to terminate the first STK session to handle the second STK session.

Abstract: This application describes techniques for dynamic feature-dependent electronic subscriber identity module (eSIM) profile provisioning for wireless devices, including provisioning of device-compatible eSIM profiles and mitigation of provisioned device-incompatible eSIM profiles. A wireless device can provide information regarding additional device capabilities indicating support (or lack thereof) for optional cellular wireless standard features to a provisioning server, which can select an eSIM profile matched to the wireless device. In some cases, a wireless device detects an error condition resulting from enabling a device-incompatible eSIM profile on an embedded universal circuit card (eUICC) of the wireless device, disables the errant eSIM profile, and notifies a provisioning server regarding the error condition. The provisioning server can account for the device compatibility when providing additional eSIM profiles to the wireless device.

Abstract: This Application sets forth techniques for managing communication with wireless devices that have been flagged due to certain activity. In particular, the techniques effectively eliminate unnecessary interactions and enable enhanced user feedback when wireless devices that have been flagged are attempting to interact with mobile network operators (MNOs). The techniques can be implemented by a variety of entities to achieve different and efficient results under various scenarios. Such entities can include, for example, i) equipment identity registries that track unique identifiers of wireless devices that have been flagged due to certain activity, ii) MNO servers, such as SM-DP+ servers, and iii) wireless devices. Additionally, individual components within wireless devices can implement the techniques variously, including using issuer security domain root (ISD-R) components, local profile assistants (LPAs), electronic subscriber identity module (eSIM) components, and/or baseband components included in the wireless devices.

Abstract: A method performed by a user equipment that is in communication with a network, includes receiving, a CAG information list from the network, the CAG information list including one or more CAG IDs and an association between each of the one or more CAG IDs and one or more NPN PLMN IDs. The method includes receiving, from the network, a network name list including one or more network names and the one or more CAG IDs and an association between each of the one or more network names and the one or more CAG IDs in the CAG information list, selecting a CAG cell as a serving cell based at least on the CAG information list or the network name list, and sending to a SIM of the UE, CAG data based on the CAG information list and the network name list.

Abstract: The described embodiments set forth techniques for testing a wireless device configured to use an embedded Universal Integrated Circuit Card (eUICC) and excluding a removable UICC card. A test apparatus processes application protocol data units (APDUs) for conformance with a standardized test specification, where the APDUs are provided by an eSIM command handler client application that interfaces with a baseband processor in communication with the eUICC that includes test profiles with test applets.

Abstract: This Application sets forth techniques for profile, e.g., subscriber identity module (SIM) and electronic SIM (eSIM), and cellular wireless service subscription management for a wireless device. The wireless device can support multiple profiles, such as dual SIMS or a single SIM and one or more eSIMs. A user of the wireless device can flexibly enable and disable various eSIMs or change the use of physical SIMs with different associated cellular wireless service subscriptions, and mapping of subscription modules to logical channels and physical hardware interfaces can occur automatically, with mechanisms to reset interfaces when required.
