Abstract
Embodiments of the present invention disclose a method, an apparatus, and a system for supporting multiple IMSIs. The method includes: receiving a response message that is returned by a server in response to an IMSI update request message and transmitted by a user terminal; and executing an IMSI update operation for a smart card according to information carried in the response message, where the smart card is a smart card supporting multiple IMSIs, and the IMSI update operation for the smart card includes: an operation of adding an IMSI in the smart card or an operation of deleting an IMSI from the smart card. The foregoing technical solution may dynamically update an IMSI in the smart card, thereby avoiding a phenomenon that one user must occupy multiple IMSIs all along, improving a utilization ratio of IMSIs, and saving IMSI resources.
