Systems and methods of automatically pre-provisioning embedded subscriber identification module (ESIM) profiles on an information handling system

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.
