1. A method performed by a first terminal for a device change from the first terminal to a second terminal in a wireless communication system, the method comprising:
identifying selection for a first profile associated with the device change by receiving input from a user;
obtaining an embedded universal integrated circuit card (eUICC) identifier (EID) of the second terminal for the device change through scanning the EID in a quick response (QR) code format outputted in the second terminal or receiving input from the user;
transmitting, to a network entity, a message including an integrated circuit card identifier (ICCID) for the first profile and the EID of the second terminal; and
providing, to the second terminal, an activation code, based on which a second profile corresponding to the first profile is downloaded from the network entity to the second terminal,
wherein the EID is associated with the second profile corresponding to the first profile.
