Data update method, apparatus, and embedded universal integrated circuit card

A data update method, wherein the method is applied to an embedded universal integrated circuit card eUICC in which a management apparatus and at least one secure element SE are disposed, wherein the at least one SE is configured to store an application corresponding to at least one profile, and the management apparatus is configured to manage the at least one SE;

• and the method comprises:
• receiving, by the management apparatus, a profile enabling request, wherein the profile enabling request is used to switch a source profile to a target profile, the profile enabling request comprises identifier information of the target profile, and the source profile is a profile that is in an enabled state before the switching;
• and
• updating, by the management apparatus, a first correspondence to a second correspondence according to the profile enabling request, wherein
• the first correspondence is a correspondence between a first application set and the source profile, and the first application set comprises at least one application in the at least one SE;
• and the second correspondence is a correspondence between a second application set and the target profile, and the second application set comprises at least one application in the first application set.
