Abstract: Some embodiments relate to methods and systems for initiating and transferring cellular subscription service using associated cellular communication devices. Cellular service may be initiated for a first cellular communication device via a second cellular communication device. The first cellular communication device may be provisioned to operate in an independent mode. In other scenarios, cellular service may be transferred from the first cellular communication device operating in independent mode to a third cellular communication device, which may be provisioned to operate in independent mode.

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: 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: Apparatus and methods to transfer user preferences for cellular wireless service associated credentials transferred from a source device to a target device. Transfer of credentials can include physically moving a physical subscriber identity module (SIM) card between devices, transfer of cellular wireless service from a first SIM card at the source device to a second SIM card at the target device, and/or transfer of cellular wireless services for one or more electronic SIMs (eSIMs) from the source device to the target device. Preferences associated some or all of the transferred SIMs/eSIMs can be applied at the target device when certain matching criteria of the SIMs/eSIMs are satisfied. Exemplary matching criteria include matching identifiers, such as integrated circuit card identifier (ICCID) values, mobile station international subscriber directory number (MSISDN) values, and/or mappings thereof. Transfer of preferences can occur via a local peer-to-peer connection, a secure cloud-based service, and/or a backup and restore process.

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: A secure element (SE) determines a profile type and a privilege level. The privilege level, in some embodiments, is associated with a key used successfully by the SE to verify a cryptographic signature. In some embodiments, the privilege level is indicated by a privilege value read from an extension field of a root certificate. The SE determines, in some instances, whether to accept or reject a profile installation after comparing the profile type with the determined privilege level. Thus, a test server is allowed to provision a test profile to an SE even if the test server does not have commercial certification required of an electronic subscriber identity module (eSIM) server that provisions operational profiles. Because the test profile does not include credentials useful for network access, the lower-security test server does not create a risk of improper access to the network of a mobile network operator (MNO).

Abstract: Disclosed herein are different techniques for enabling a mobile device to dynamically support different authentication algorithms. A first technique involves configuring an eUICC included in the mobile device to implement various authentication algorithms that are utilized by MNOs (e.g., MNOs with which the mobile device can interact). Specifically, this technique involves the eUICC storing executable code for each of the various authentication algorithms. According to this technique, the eUICC is configured to manage at least one eSIM, where the eSIM includes (i) an identifier that corresponds to one of the various authentication algorithms implemented by the eUICC, and (ii) authentication parameters that are compatible with the authentication algorithm. A second technique involves configuring the eUICC to interface with an eSIM to extract (i) executable code for an authentication algorithm used by an MNO that corresponds to the eSIM, and (ii) authentication parameters that are compatible with the authentication algorithm.

Abstract: Secure reception of a certificate revocation list (CRL) is determined. In some embodiments, a device initiates a CRL update by sending a message with a timestamp to an embedded universal integrated circuit card (eUICC). The eUICC generates a session identifier, nonce, or random number and builds a payload including an internal time value based on a server time, and an internal time value based on a past message received from the device. The eUICC cryptographically signs over the payload and sends it to the device. The device obtains a CRL from a host server, checks the CRL, and, if the CRL passes the device check, sends it to the eUICC along with a second device timestamp and the nonce. The eUICC then performs checks based on the timestamps, the nonce, the CRL and the internal time values to determine whether the CRL has been securely received.
