1. A method performed by a device operating with an embedded universal integrated circuit card (eUICC) in a wireless communication system, the method comprising:
identifying, by a local profile assistant (LPA) of the device, information associated with a target profile required to be enabled;
sending, by the LPA to the eUICC, a first message to enable the target profile, the first message including a refresh flag indicating whether a refresh of the target profile is required and a port number of a target port corresponding to the target profile;
in case that the refresh flag indicates that the refresh of the target profile is required, receiving, by a baseband component of the device from the eUICC, a second message to trigger the refresh of the target port; and
after receiving the second message, sending, by the baseband component to the eUICC, a terminal response message, or resetting, by the baseband component, the target port.
