  • Patent number: 11671833
    Abstract: Embodiments described herein relate to transfer of credentials between two mobile wireless devices that are within proximity of each other, via a secure local connection, or via a network-based cloud service, where the two mobile wireless devices are not in proximity to each other. Transfer of credentials can include communication between a source device, a target device, and/or one more network-based servers, which can include mobile network operator (MNO) managed servers, such as an entitlement server, a web-sheet server, an authentication server, a provisioning server, a subscription management data preparation (SM-DP+) server, a home subscriber server (HSS), and/or an authentication server, as well as third-party managed servers, such as a cloud service server and/or an identification services server. Authentication can be based at least in part on one or more tokens and/or a trust flag obtained by the source device and provided to the target device.

  • Publication number: 20230171585
    Abstract: Systems and methods for facilitating transfer of an eSIM subscription from a source device to a target device. In one embodiment, a source device includes a transceiver and a processor system. The processor system includes an eUICC configured to store an eSIM associated with an eSIM subscription. The processor system is configured to transmit, via the transceiver and to an eSIM subscription manager server, a request for an eSIM subscription transfer activation code; receive, via the transceiver and at least partly in response to the request, a server nonce; generate a signed payload using the server nonce and source device information; transmit, via the transceiver and to the eSIM subscription manager server, the signed payload; receive, via the transceiver and in response to transmitting the signed payload, the eSIM subscription transfer activation code; and provide the eSIM subscription transfer activation code to the target device or a user thereof.

  • Publication number: 20230081421
    Abstract: The described embodiments set forth techniques for transferring an electronic subscriber identity module (eSIM) with the same integrated circuit card identifier (ICCID) value from a source mobile wireless device to a target mobile wireless device directly with a mobile network operator (MNO) provisioning server. The target mobile wireless device downloads the eSIM from the MNO provisioning server after deletion of the eSIM on the source mobile wireless device and reassignment of the eSIM with the same ICCID value to the target mobile wireless device.

  • Publication number: 20230083018
    Abstract: The described embodiments set forth techniques for recovering one or more electronic subscriber identity modules (eSIMs) previously deleted from an embedded universal integrated circuit card (eUICC) of a mobile wireless device. Prior to deletion of an eSIM, the mobile wireless device uploads first eSIM subscription information to a cloud network services server and stores second eSIM subscription information in a secure memory of the eUICC. The mobile wireless device can subsequently download the first eSIM subscription information to verify matching to the second eSIM subscription information stored in the eUICC before displaying an option for recovering the eSIM. The mobile wireless device sends to a mobile network operator (MNO) provisioning server an eSIM recovery request notification that includes at least a portion of the first eSIM subscription information, and the MNO provisioning server provides an eSIM recovery response message indicating approval and a network address to download the eSIM.

  • Publication number: 20230073252
    Abstract: This Application sets forth techniques for provisioning and activating an electronic subscriber identity module (eSIM) as a primary SIM for a mobile wireless device that includes a limited functionality physical SIM (pSIM) associated with a particular mobile network operator (MNO) and installed in the mobile wireless device at a time of manufacture. An eSIM associated with the particular MNO is reserved during a sales order process and later activated during device activation after receipt by a user using a secure over-the-air (OTA) cellular connection enabled by the limited functionality pSIM, when a non-cellular connection or other Internet accessible connection is available. Dual SIM device configuration processes can be suppressed during activation of the eSIM. After successful attachment of the mobile wireless device to a cellular wireless network of the particular MNO using credentials of the eSIM, the limited functionality pSIM is disabled.

  • Publication number: 20230018945
    Abstract: 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.

  • Publication number: 20230020761
    Abstract: This Application sets forth techniques for provisioning and activating electronic subscriber identity modules (eSIMs) for mobile wireless devices. An eSIM is reserved during a sales order process and later activated during device activation after receipt by a user. An option for eSIM installation in place of (or in addition to) physical SIM installation is provided when purchasing the mobile wireless device. The reserved eSIM can replace a previous SIM/eSIM or be a new eSIM. During device activation, installation and activation of the eSIM occurs. Activation of the eSIM can occur before or after deactivation of a transferred SIM/eSIM. The mobile wireless device accounts for propagation delay of eSIM activation through MNO servers by disabling and re-enabling the eSIM until initial attachment to an MNO cellular wireless network succeeds or a maximum number of retry attempts is reached.

  • Publication number: 20220394492
    Abstract: Apparatuses, systems, and methods for network interface management for Citizens Broadband Radio Service (CBRS) deployments, e.g., in LTE and/or 5G NR systems and beyond, including methods for coarse selection of CBRS networks and fine selection of CBRS networks as well as support for multiple CBRS networks. Coarse selection of CBRS networks may include various triggers for automatic CBRS profile enabling and/or disabling, user management and overriding of system selections, tiered hierarchy for CBRS network enabling and/or disabling, as well as mechanisms to avoid ping-ponging between network selection. Fine selection of CBRS networks may include data slot switching between mobile network operators (MNOs, e.g., LTE/NR macro cells) and CBRS eSIM as well as prioritization of CBRS networks over Wi-Fi networks. Multiple CBRS networks support may include CBRS network identifier (NID) matching for unique identification as well as user-ranked CBRS priority.

  • Publication number: 20220386104
    Abstract: 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.

  • Publication number: 20220279353
    Abstract: Methods and devices for a user equipment (UE) device to utilize an electronic subscriber identity module (eSIM) to provide backup cellular connectivity for essential services and security enhancements. A UE device receives user input to alter an operational state of the UE. The user input may include removing a physical subscriber identity module (SIM) card installed in the UE or attempting to power off the UE. In response to receiving the user input, an authorization process is initiated. In response to determining that the authorization process has failed, a security enhancement is implemented for the UE.
