Abstract: A method of provisioning an embedded subscriber identification module (eSIM) profile on an information handling system may include, with an embedded controller (EC), detecting a powering up process at the information handling system; with the execution of the EC, establishing an out-of-band (OOB) connection with a subscription manager-discovery server (SM-DS) to communicate an electronic identification confirming that the information handling system has an authentic subscription to services provided by a wireless wide area network (WWAN) carrier, the OOB connection being established at a level below an operating system (OS) of the information handling system; receiving a WWAN carrier eSIM profile over the OOB connection including an international mobile equipment identity (IMEI); installing the eSIM carrier profile with an embedded universal integrated circuit card (eUICC); and initiating a subscription confirmation with a WWAN carrier.

Abstract: A method of securing functionalities of an integrated subscriber identification module (iSIM) on an information handling system may include with an embedded controller (EC), detecting a powering-up process at the information handling system and determine a chain of trust access keys during bootup; with the execution of the EC, detecting and activating a wireless wide area network (WWAN) module; with the execution of the EC, detecting and accessing an integrated subscriber identity module (iSIM); with the execution of the EC, authenticating access to iSIM content including authorization information and carrier profile information with the chain of trust access keys generated from encryption keys based on digital signatures; and sending the authorization information and carrier profile information form the iSIM to the WWAN module for authentication, wirelessly, with a switched multimegabit data service (SM-DS) server associated with the carrier profile.
