This, in turn, requires some way through which an enterprise (or school) should be able to provide the EIDs of their PCs to the operator as part of their contract with the mobile operator. In addition to a Windows 11 Connected PC (eSIM-capable PC) managed through Microsoft Intune, you need the following information:Ī mobile operator who can provide eSIM profiles to a set of known devices based upon their EIDs. In addition, the enterprise can also configure some eSIM policies through the CSP and each PC obtains its eSIM profile from the CSP. Within Windows, the eUICCs Configuration Service Provider (CSP) handles eSIM configuration. After the PC is configured with the eSIM information, it downloads the eSIM profile from the mobile operator's download server (SM-DP+). When the MDM server is enrolled to the end user's work or school account, it pushes the configuration to the PC throughout its lifecycle. When an enterprise provisions an eSIM through an MDM such as Microsoft Intune, it also configures the eSIM deployment along with other enterprise settings and policies. To support larger-scale managed environments (such as an enterprise or an educational organization), Windows provides eSIM provisioning through mobile device management (MDM) such as Microsoft Intune. However, it requires user interaction on each device that is provisioned, an effort and cost that may become significant at large scale. The Mobile Plans application is well suited to the needs of consumers and businesses with a few PCs. The Mobile Plans application in Windows further reduces friction by providing a user-friendly interface for a user to interact with a chosen mobile operator and coordinate the download and installation of the corresponding eSIM profile. At-Scale Configuration of eSIM PCsĮSIM digitizes the delivery of SIMs to devices such as PCs, eliminating the need to obtain and deploy physical SIM cards. The combination of the enabled eSIM Profile and its eUICC container behaves exactly like a traditional SIM card. One of the installed eSIM Profiles is enabled (and the rest are disabled). Multiple eSIM Profiles may be installed into an eUICC. The credentials and associated other configuration that uniquely identify a cellular subscription are contained in a digital (software) package called an eSIM Profile. In the same way that each physical SIM card has a unique identity, each eUICC has a unique identity called eUICC Identifier (EID). The secure container is called an eUICC (embedded Universal Integrated Circuit Card). Windows has supported eSIM for PCs since 2017.ĮSIM decouples the secure execution environment of the plastic SIM card from the SIM credentials it contains. The adoption of eSIM technology has been growing due to its incorporation in popular smart phones. About eSIM technologyĮSIM technology has created a worldwide ecosystem of cellular devices and mobile operators based upon a common specification from the GSM Association (GSMA). Windows 11 provides more capabilities for the deployment and management of eSIM content using Mobile Device Management (MDM) such as Microsoft Intune. Therefore, Windows 10 and Windows 11 support eSIM (embedded Subscriber Identity Module) technology as a digital alternative to discrete SIM cards. Management of SIM cards for a fleet of devices can be costly and time-consuming. The identity of a cellular-enabled device, such as a Windows Connected PC, has traditionally been encapsulated in a device called SIM (Subscriber Identity Module), and packaged as a discrete SIM card.
