Embodiments provided herein identify a certificate issuer (CI) to be relied on as a trusted third party by an electronic subscriber identity module (eSIM) server in remote SIM provisioning (RSP) transactions with an embedded universal integrated circuit card (eUICC). In an RSP ecosystem, multiple CIs may exist. Parties rely on public key infrastructure (PKI) techniques for establishment of trust. Trust may be established based on a trusted third party such as a CI. Parties need to agree on the CI in order for some PKI techniques to be useful. Embodiments provided herein describe approaches for an eUICC and an eSIM server to arrive at an agreed-on CI. Candidate or negotiated CIs may be indicated on a public key identifier (PKID) list. A PKID list is distributed, in some embodiments, by means of a discovery server, via an activation code (AC) and/or during the establishment of a profile provisioning session.

Managing embedded universal integrated circuit card (eUICC) provisioning with multiple certificate issuers (CIs)

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.

Electronic subscriber identity module (eSIM) eligibility checking

Representative embodiments described herein set forth techniques for provisioning bootstrap electronic Subscriber Identity Modules (eSIMs) to mobile devices. According to some embodiments, a mobile device can be configured to issue, to an eSIM selection server, a bootstrap eSIM request that includes (i) metadata associated with the mobile device, and (ii) metadata associated with an electronic Universal Integrated Circuit Card (eUICC) included in the mobile device. In turn, the eSIM selection server selects and binds a particular bootstrap eSIM to the mobile device, and provides information to the mobile device that enables the mobile device to obtain the particular bootstrap eSIM from one or more eSIM servers. When the mobile device obtains the particular bootstrap eSIM, the mobile device can interface with a mobile network operator (MNO) and obtain a complete eSIM that enables the mobile device to access services provided by the MNO.

Techniques for provisioning bootstrap electronic subscriber identity modules (eSIMs) to mobile devices

A pool of devices is initially associated under a single product type identifier, for example, a single stock keeping unit (SKU) identifier. Each device is associated with a secure element (SE), for example, an embedded universal integrated circuit card (eUICC). A wireless telecommunications carrier purchases a subset of the devices from the owner of the pool of devices. A policy management server receives a shipment record and associates the subset of devices with a product identifier and with a carrier-specific activation policy. The policy management server sends an electronic subscriber identity module (eSIM) reservation request to a policy evaluation server, which contacts an eSIM delivery server associated with the purchasing carrier. The eSIM delivery server reserves eSIMs for the purchased devices. When an end user buys one of the devices from the subset, the purchased device is provisioned by the eSIM delivery server with the eSIM reserved for that device.

Electronic subscriber identity module (eSIM) assignment for carrier channel devices

Methods, devices, and servers for as-needed update of a trusted list are provided herein. An electronic subscriber identity module (eSIM) server receives a request for an eSIM of a particular type from a wireless device. The eSIM server evaluates the particular type and requests an eSIM of the particular type from a second eSIM server, which is not initially trusted by a secure element (SE) of the wireless device. The eSIM server sends a policy update to the wireless device. The wireless device passes the policy update to the SE, for example, a universal integrated circuit card (UICC). The UICC updates the trusted list with an identity of the second eSIM server. When the wireless device downloads a bound profile package (BPP) containing an eSIM from the second eSIM server, the UICC validates the BPP based on the updated trusted list. The eSIM is then installed on the UICC.
