Abstract

This application is applicable to the field of communications technologies, and provides an embedded subscriber identity module (eSIM) card identification method and a terminal device method. The method includes: after completing an initialization process, driving an eSIM card to be powered on; querying whether an activated profile exists in the eSIM card; and when a query result is that no activated profile exists in the eSIM card, powering off the eSIM card. When the eSIM card is not activated or no activated profile exists in the eSIM card, it indicates that a user does not need to use a related function or service of the eSIM card. In this case, the eSIM card is powered off. When the eSIM card is not activated, it means that no profile exists in the eSIM card.
