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.

Abstract: Some embodiments relate to methods for provisioning a secondary wireless device with an eSIM for wireless communication and activating multi-SIM functionality between the secondary wireless device and a primary wireless device having a subscribed SIM. The primary wireless device may act as a proxy in obtaining the eSIM for the secondary wireless device. The primary wireless device may then provide, to the cellular network, identifiers of the SIMs of the primary and secondary wireless devices. The primary wireless device may then request initiation of multi-SIM functionality for the two SIMs, and receive an indication that the multi-SIM functionality has been initiated. As an example, the multi-SIM functionality may be implemented by mapping the SIM of the primary wireless device and the SIM of the secondary wireless device (e.g., the provisioned eSIM) to the same Mobile Directory Number (MDN).

Abstract: Techniques to manage updates for eSIMs of a secondary wireless device are disclosed. Responsive to a user input, expiration of a timer, receipt of a message from an associated primary wireless device, processing circuitry of the secondary wireless device commands an eUICC to update an eSIM. A secure data connection is established between the eUICC and a network provisioning server, either directly from the secondary wireless device to a cellular wireless network or relayed indirectly via the primary wireless device. The eUICC and the network provisioning server exchange messages in accordance with a BIP process to update the eSIM. The eUICC provides a status to the processing circuitry indicating success or failure for the eSIM update. Upon success, a portion of the secondary wireless device may be placed in a reduced power state. Upon failure, the eSIM update process may repeat up to a maximum number of retries.

Abstract: Apparatuses, systems, and methods for multi-SIM user equipment (UE) devices to perform data operations with a packet data network of a carrier associated with a first SIM of the UE. An indication of a requested data operation with the packet data network of the carrier associated with the first SIM of the UE may be received. The UE may be operating in a dual SIM mode in which the packet data network of the carrier associated with the first SIM of the UE is unavailable. It may be determined if one or more conditions for performing the requested data operation are present and if a data path to perform the requested data operation is available. The requested data operation may be performed if the one or more conditions for performing the requested data operation are present and if a data path to perform the requested data operation is available.

Abstract: This disclosure relates to techniques for performing Wi-Fi authentication in a wireless communication system. Public key cryptography may be used to enhance the confidentiality of the user's permanent identity in transit. In some embodiments, a RSA-OAEP(SHA-256) encryption scheme may be used to protect the permanent identity when the EAP client needs to send the user's permanent identity to the server in the absence of pseudonym or fast re-authentication identity. In some embodiments, a server certificate is used to authenticate a iWLAN tunnel to protect an IMSI during setup of a Wi-Fi call. Using the methods described herein on both or either of the EAP client and server side may offer improved privacy protection.

Abstract: This application sets forth techniques for provisioning electronic subscriber identity modules (eSIMs) to mobile wireless devices that do not include functional bootstrap provisioning profiles to obtain access to a cellular wireless network. Connectivity to a cellular wireless network can be allowed for provisioning one or more eSIMs to a mobile wireless device using hardware device identifiers for authentication and a limited purpose provisioning connection when the cellular wireless network supports provisioning connections without the use of a provisioning profile for access.

Abstract: This disclosure relates to techniques for performing Wi-Fi authentication using an entitlement server in a wireless communication system. A wireless station may perform authentication with a carrier network entitlement server, using a protocol other than Wi-Fi. The wireless station may receive a Wi-Fi service token as part of the authentication with the carrier network entitlement server. The wireless station may perform Wi-Fi authentication with a Wi-Fi access point associated with the carrier network using the Wi-Fi service token. After performing Wi-Fi authentication using the Wi-Fi service token, the wireless station may communicate with the carrier network by way of the Wi-Fi access point.
