Description

ESIM identification method and related device Technical Field The application relates to the technical field of electronics, in particular to an eSIM identification method and a related device. Background The mobile communication device may access the mobile communication network based on a user identity authentication of a subscriber identity module (Subscriber Identity Module, SIM). Traditional SIM cards need to be opened and activated by a mobile operator in advance and then inserted into a physical card slot of an electronic device after opening and activation. Based on the SIM card, the data communication services such as dialing, answering and receiving and sending short messages can be realized. After the user uses the traditional SIM card, the key configuration files in the SIM card cannot be updated any more. With the development of mobile communication technology, an Embedded SIM (eSIM) card is proposed on the basis of a conventional SIM card. Compared with the traditional SIM card, the eSIM card is programmable, and can be remotely configured through Over-the-Air Technology (OTA), so as to realize functions of remote card opening, activation, deactivation and the like.
