Abstract
A method for authenticating and updating an embedded universal integrated circuit card (eUICC) firmware version includes receiving first information from a terminal device, where the first information includes a target identifier, searching a currently stored event record for a target event record, where a group event identifier in the target event record matches the target identifier in the first information, sending the target event record to the terminal device, where the target event record is used to enable the terminal device to download an eUICC firmware version update package, and updating a firmware version of an eUICC of the terminal device based on the eUICC firmware version update package.
