METHOD AND APPARATUS FOR INSTALLING AND MANAGING MULTIPLE eSIM PROFILES

A method performed by an embedded universal integrated circuit card (eUICC) in a wireless communication system, the method comprising:

• receiving, from a local profile assistant (LPA) of a terminal, a first message to enable a target profile, the first message including a refresh flag and a port number corresponding to the target profile;
• identifying whether the refresh flag is set in the first message;
• and
• in case that the refresh flag is set in the first message, sending, to a modem of the terminal, a second message to initiate a status refresh of the modem including the port number.

A terminal in a wireless communication system, the terminal comprising:

• a local profile assistant (LPA) configured to:
• identify information associated with a target profile required to be enabled, and
• send, to an embedded universal integrated circuit card (eUICC), a first message to enable the target profile, the first message including a refresh flag and a port number corresponding to the target profile;
• and
• a modem configured to:
• in case that the refresh flag is set in the first message, receive, from the eUICC, a second message to initiate a status refresh of the modem including the port number, and
• in case that the refresh flag is not set in the first message, receive, from the LPA, the port number.
