Claim 7:
8. An information handling system operating an embedded subscriber identification module (eSIM) provisioning system comprising:
an embedded controller (EC), memory, and network interface device;
an eSIM provisioning system including an embedded universal integrated circuit card (eUICC) to receive an eSIM profile for accessing a wireless link with a pre-subscribed wireless wide area network (WWAN) carrier;
the EC accessing pre-installed code instructions and a carrier information database with a manufacturer-assigned electronic 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, upon powering up of the information handling system and with the EC prior to start up of an operating system (OS), establish an out-of-band (OOB) connection with a subscription manager-discovery server (SM-DS) at the pre-subscribed WWAN carrier, transmit the manufacturer-assigned electronic identification, and initiate a download of a WWAN carrier eSIM profile pre-reserved at the SM-DS via a separate communication from the information handling system manufacturer for a subscription with the pre-subscribed WWAN carrier by comparison to a carrier verification request profile specific to the information handling system received from the information handling system manufacturer at pre-subscribed WWAN carrier with the manufacturer-assigned electronic identification; and
the wireless interface device downloading the WWAN carrier eSIM profile including international mobile subscriber identity (IMSI) to the eUICC via the OOB connection and a processor continuing to boot up the OS of the information handling system and use the eUICC to establish a wireless link with the pre-subscribed WWAN carrier.
