Abstract
A method for authenticating and updating an eUICC firmware version includes receiving first information sent by a terminal device, where the first information includes a target identifier. The method further includes 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. The method further includes 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. The method further includes updating a firmware version of an eUICC of the terminal device based on the eUICC firmware version update package.
