[ 18. A method for supporting multiple international mobile subscriber identities (IMSIs), comprising:
receiving a response message that is returned by a server in response to an IMSI update request message transmitted by a user terminal for an IMSI update operation for a smart card, wherein the IMSI update request message comprises: an IMSI application request message and/or an IMSI deletion request message, the IMSI application request message is used to apply to the server for a new IMSI, the IMSI deletion request message is used to cancel a certain IMSI occupied by the smart card; and
executing the IMSI update operation for the smart card according to information carried in the response message, wherein the smart card is a smart card supporting multiple IMSIs, and the IMSI update operation for the smart card comprises: an operation of adding a new IMSI in the smart card according to the IMSI application request message and/or an operation of deleting an occupied IMSI from the smart card according to the IMSI deletion request message;
wherein executing the IMSI update operation for the smart card according to the information carried in the response message comprises:
performing security authentication on the response message; and
after the security authentication is passed, decrypting the response message and executing the IMSI update operation for the smart card according to the decrypted information.]
