Claim 14:
15. An information handling system operating an embedded subscriber identification module (eSIM) provisioning system comprising:
processor, memory, and network interface device;
an eSIM provisioning system including an embedded universal integrated circuit card (eUICC) prepared to receive an eSIM profile with the eSIM being left blank of the eSIM profile with eSIM credentials by a manufacturer of the information handling system;
an embedded controller (EC) accessing pre-installed code instructions and a carrier information database with a manufacturer-assigned unique device identification of the information handling system and pre-subscribed carrier information identifying a pre-subscribed wireless wide area network (WWAN) wireless carrier for WWAN service upon ordering the information handling system from an information handling system manufacturer;
a wireless interface device to establish an out-of-band (OOB) connection with a subscription manager-discovery server (SM-DS) of the pre-subscribed WWAN wireless carrier and download a wireless wide area network (WWAN) carrier eSIM profile with provisioned eSIM credentials pre-reserved at the SM-DS received via a communication from the information handling system manufacturer upon providing the manufacturer-assigned unique device identification (ID) for the information handling system assigned by the manufacturer and based on the information handling system manufacturer's build of the information handling system;
the processor, after the downloading of the WWAN carrier eSIM profile for the pre-subscribed WWAN wireless carrier, completing a boot-up process of a binary input/output system (BIOS) and an operating system (OS) and initiating communication with the pre-subscribed WWAN wireless carrier associated with the WWAN carrier eSIM profile via an LTE antenna system of the wireless interface device using the provisioned eSIM credentials.
