Abstract: The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. A method and an apparatus for providing a dual subscriber identity module (SIM) function even in a terminal with a single embedded universal integrated circuit card (eUICC) mounted are provided. A method and an apparatus for installing, activating, and managing a plurality of profiles are provided, so that even a terminal with a single eUICC mounted may provide a dual SIM function in a communication system. The method includes the following embodiments to achieve the foregoing aspect, a method in which an eUICC receives a command involving a profile state change from a local profile assistant (LPA), registers a proactive command, and notifies a modem of logical interface information for obtaining the proactive command, a method in which the eUICC determines whether to perform polling on a specific logical interface by combining predetermined information, such as the logical interface information received from the mode, the state of a logical interface collected and possessed by the modem, and the number of an interface on which a corresponding message is received, a method in which the modem receives and processes the proactive command by performing polling on the logical interface, and a method in which the eUICC receives the result of processing the proactive command and completely changes the state of a profile connected to the logical interface. Further, a method in which the eUICC selectively configures a REFRESH message depending on whether the modem supports multiple enabled profiles (MEP) and divisively transmits the message to the modem when the eUICC receives a request for eUICC memory resetting or a profile state change in the terminal may be provided.
