in step 203, the target MSISDN and the target card location identifier are sent to a server, and the server determines target card writing information corresponding to the SIM card according to the target MSISDN and the target card location identifier;

in step 204, after receiving the target card writing information returned by the server, sending the target card writing information to the SIM card, and writing the card by using the SIM card as the information corresponding to the card position indicated by the target card position identifier.

In the above embodiment, the terminal may obtain the target MSISDN selected by the user and the target card location identifier sent by the SIM card, so as to send the target MSISDN and the target card location identifier to the server, after the server determines the target card writing information corresponding to the SIM card, the target card writing information is sent to the terminal, and the terminal forwards the target card writing information to the SIM card, so that the SIM card writes the target card. The purpose of writing the card through the terminal is achieved, the card writing can be completed under the condition of being connected with the Internet, and the usability is higher.

In connection with the above step 201, the terminal may provide at least one usable MSISDN to the user through the target App, and the user selects one MSISDN among the usable MSISDNs as the target MSISDN.

For step 202, the terminal may send an acquisition request to the SIM card by the target App, requesting to acquire the target card location identifier. And the terminal carries out authorization verification on the target App, and after the authorization verification is passed, the terminal sends the position identification of the target card to the target App through the target interface.

The target App may call a pre-specified API (Application Programming Interface), such as a phonebook API in the android system, to read the target card location identification.

Aiming at the step 203, the terminal can send the target MSISDN and the target card position identifier to the server through the target App, and the server determines the target card writing information corresponding to the SIM card according to the target MSISDN and the target card position identifier.
