  • Publication number: 20250150829
    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.

  • Patent number: 12294864
    Abstract: The described embodiments set forth techniques for management of electronic subscriber identity module (eSIM) profiles for a wireless device, including in-field replacement of provisioning (bootstrap) eSIM profiles. Public key infrastructure (PKI) information for an original equipment manufacturer (OEM) profile management server is installed in an embedded universal integrated circuit card (eUICC) of a wireless device at a time of manufacture and used subsequently by the wireless device to conduct an eSIM profile management session and verify authorization of the OEM profile management server to manage, e.g., update and/or replace, one or more eSIM profiles on the eUICC of the wireless device.

  • Patent number: 12273957
    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.

  • Publication number: 20240080654
    Abstract: This application sets forth techniques for dynamically managing a provisioning electronic subscriber identity module (eSIM) for a wireless device. A provisioning eSIM is installed in the wireless device to provide a limited functionality connectivity option for essential services, such as device activation and user eSIM provisioning. To reduce signaling load on a network and to conserve wireless device battery power, the provisioning eSIM is reconfigured between an inactive state and an active state dynamically based on user actions and system requirements.

  • Patent number: 11012852
    Abstract: Embodiments described herein relate to mechanisms for error recovery during transfer of cellular service credentials between two mobile wireless devices. Transfer of credentials includes communication between a source device, a target device, and/or one more network-based servers. Authentication can be based on one or more tokens obtained by the source device and provided to the target device. Error recovery can include using redirection to different servers, providing alternative information for authentication, and storage and subsequent retrieval of information to restart or complete a credential transfer process.
