An embedded universal integrated circuit card eUICC profile management method, wherein the method comprises: when an operating system of the eUICC needs to be updated, setting (S307), by a local profile assistant LPA, an operating system update flag, wherein the operating system update flag is used to identify that the eUICC is in an update status; obtaining (S308), by the LPA, metadata of a first profile, wherein the metadata of the first profile is used to indicate status information of the first profile of the eUICC; sending (S321), by the LPA, a profile obtaining request to a profile server , wherein the profile obtaining request comprises an eUICC identifier, a profile identifier, and the operating system update flag; receiving, by the LPA, the second profile sent by the profile server , and installing the second profile in the eUICC; configuring, by the LPA, metadata of the second profile based on the metadata of the first profile; and activating, by the LPA, the second profile based on the metadata of the second profile, wherein the configuring, by the LPA, metadata of the second profile based on the metadata of the first profile comprises: replacing, by the LPA, the metadata of the second profile with the metadata of the first profile; or when field content of the metadata of the first profile is different from field content of the metadata of the second profile, replacing, by the LPA, the field content of the second profile with the field content of the first profile. when an operating system of the eUICC needs to be updated, setting (S307), by a local profile assistant LPA, an operating system update flag, wherein the operating system update flag is used to identify that the eUICC is in an update status; obtaining (S308), by the LPA, metadata of a first profile, wherein the metadata of the first profile is used to indicate status information of the first profile of the eUICC; sending (S321), by the LPA, a profile obtaining request to a profile server , wherein the profile obtaining request comprises an eUICC identifier, a profile identifier, and the operating system update flag; receiving, by the LPA, the second profile sent by the profile server , and installing the second profile in the eUICC; configuring, by the LPA, metadata of the second profile based on the metadata of the first profile; and activating, by the LPA, the second profile based on the metadata of the second profile, wherein the configuring, by the LPA, metadata of the second profile based on the metadata of the first profile comprises: replacing, by the LPA, the metadata of the second profile with the metadata of the first profile; or when field content of the metadata of the first profile is different from field content of the metadata of the second profile, replacing, by the LPA, the field content of the second profile with the field content of the first profile. replacing, by the LPA, the metadata of the second profile with the metadata of the first profile; or when field content of the metadata of the first profile is different from field content of the metadata of the second profile, replacing, by the LPA, the field content of the second profile with the field content of the first profile. <EOS>
