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.

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.

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.

Abstract: Techniques to protect a subscriber identity, by encrypting a subscription permanent identifier (SUPI) to form one-time use subscription concealed identifiers (SUCIs) using a set of one-time ephemeral asymmetric keys, generated by a user equipment (UE), and network provided keys are disclosed. Encryption of the SUPI to form the SUCIs can mitigate snooping by rogue network entities, such as fake base stations. The UE is restricted from providing the unencrypted SUPI over an unauthenticated connection to a network entity. In some instances, the UE uses a trusted symmetric fallback encryption key KFB or trusted asymmetric fallback public key PKFB to verify messages from an unauthenticated network entity and/or to encrypt the SUPI to form a fallback SUCIFB for communication of messages with the unauthenticated network entity.

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.

Abstract: Representative embodiments described herein set forth techniques for optimizing large-scale deliveries of electronic Subscriber Identity Modules (eSIMs) to mobile devices. Specifically, instead of generating and assigning eSIMs when mobile devices are being activated—which can require significant processing overhead—eSIMs are pre-generated with a basic set of information, and are later-assigned to the mobile devices when they are activated. This can provide considerable benefits over conventional approaches that involve generating and assigning eSIMs during mobile device activation, especially when new mobile devices (e.g., smartphones, tablets, etc.) are being launched and a large number of eSIM assignment requests are to be fulfilled in an efficient manner.

Abstract: The embodiments set forth techniques for an embedded Universal Integrated Circuit Card (eUICC) to conditionally require, when performing management operations in association with electronic Subscriber Identity Modules (eSIMs), human-based authentication. The eUICC receives a request to perform a management operation in association with an eSIM. In response, the eUICC determines whether a policy being enforced by the eUICC indicates that a human-based authentication is required prior to performing the management operation. Next, the eUICC causes the mobile device to prompt a user of the mobile device to carry out the human-based authentication. The management operation is then performed or ignored in accordance with results of the human-based authentication.

Abstract: A method for establishing a secure communication channel between an off-card entity and an embedded Universal Integrated Circuit Card (eUICC) is provided. The method involves establishing symmetric keys that are ephemeral in scope. Specifically, an off-card entity, and each eUICC in a set of eUICCs managed by the off-card entity, possess long-term Public Key Infrastructure (PKI) information. When a secure communication channel is to be established between the off-card entity and an eUICC, the eUICC and the off-card entity can authenticate one another in accordance with the respectively-possessed PKI information (e.g., verifying public keys). After authentication, the off-card entity and the eUICC establish a shared session-based symmetric key for implementing the secure communication channel. Specifically, the shared session-based symmetric key is generated according to whether perfect or half forward security is desired. Once the shared session-based symmetric key is established, the off-card entity and the eUICC can securely communicate information.

Abstract: Embodiments provided herein determine if an electronic subscriber identity module (eSIM) associated with a requested service can be installed in a secure element (SE) housed in a wireless device. Before requesting deployment of an eSIM suitable for the requested service from an eSIM delivery server, a carrier server asks that an original equipment manufacturer (OEM) server validate that an eSIM corresponding to a customer request should be deployed. The OEM server obtains information about the wireless device and information about the SE. When the carrier server requests validation, the OEM server evaluates the wireless device information and/or the SE information. If the OEM server indicates that deployment of the eSIM should proceed, the OEM server also indicates the eSIM type that is compatible with the wireless device and with the SE housed in the device.
