Abstract
The described embodiments set forth techniques for management of electronic subscriber identity module (eSIM) profiles for a wireless device, including in-field replacement of provisioning (bootstrap) eSIM profiles. Public key infrastructure (PKI) information for an original equipment manufacturer (OEM) profile management server is installed in an embedded universal integrated circuit card (eUICC) of a wireless device at a time of manufacture and used subsequently by the wireless device to conduct an eSIM profile management session and verify authorization of the OEM profile management server to manage, e.g., update and/or replace, one or more eSIM profiles on the eUICC of the wireless device.
