This application describes cellular service transfer mechanisms that can be used to convert cellular service credentials on a physical SIM (pSIM) card included in a wireless device to a newly downloaded electronic SIM (eSIM) on an embedded universal integrated circuit card (eUICC) of the wireless device. Transfer of the credentials for cellular service access can occur locally within the wireless device with authorization to transfer obtained from a mobile network operator (MNO) entitlement server associated with the pSIM. The new eSIM corresponding to the previously used pSIM can be downloaded to the eUICC from a provisioning server of the MNO.

On-device physical SIM to eSIM conversion

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.

Profile transfer with secure intent

This Application sets forth techniques for cloud-based cellular service management for a set of associated mobile wireless devices, including maintenance of information for one or more subscriber identity modules (SIMs) and/or electronic SIMs (eSIMs) used by the set of mobile wireless devices.

Cloud-based cellular service management for mobile wireless devices

This Application describes mechanisms to transfer cellular service plans and associated credentials efficiently between wireless devices. Information regarding transferability of cellular services for SIMs/eSIMs to a wireless device are obtained from locally stored or remotely accessible cellular service information and/or associated mobile network operator (MNO) information. Access to network-based servers to determine transferability and/or to effect transfer can use non-cellular connections when available. Transferability information can be presented to a user to narrow selection of cellular service plans to transfer.

Methods and apparatus for efficient transfer of multiple cellular service credentials

This Application sets forth techniques for cloud-based cellular service management for a set of associated mobile wireless devices, including maintenance of information for one or more subscriber identity modules (SIMS) and/or electronic SIMs (eSIMs) used by the set of mobile wireless devices.

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.
