Claim 0:
1. A method of provisioning an embedded subscriber identification module (eSIM) profile on an information handling system, comprising:
with an embedded controller (EC), detecting a powering up process at the information handling system;
with execution of 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 for 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;
with the execution of the EC, establishing an out-of-band (OOB) connection with a subscription manager-discovery server (SM-DS) prior to startup of an operating system (OS) of the information handling system access the carrier information database and identify the pre-subscribed WWAN carrier and to communicate the manufacturer-assigned electronic identification to initiate download of a WWAN carrier eSIM profile pre-reserved at the SM-DS via a communication from the information handling system manufacturer for the information handling system to initiate an authentic subscription to services provided by the pre-subscribed WWAN carrier, the OOB connection being established at a level below the OS of the information handling system;
receiving the WWAN carrier eSIM profile over the OOB connection including an international mobile equipment identity (IMEI) from the pre-subscribed WWAN carrier;
installing the eSIM carrier profile with an embedded universal integrated circuit card (eUICC); and
initiating, with a processor, a subscription confirmation with the pre-subscribed WWAN carrier to establish a WWAN wireless link.
