Method and apparatus for installing and managing multiple eSIM profiles

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

• receiving, from a local profile assistant (LPA) of the device which identifies information associated with a target profile required to be enabled, 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, sending, to a baseband component of the device, a second message to trigger the refresh of the target port;
• and
• after sending the second message, upon reception of a terminal response message from the baseband component or after resetting the target port, enabling the target profile on the target port.

A device operating with an embedded universal integrated circuit card (eUICC) in a wireless communication system, the device comprising:

• a local profile assistant (LPA) configured to:
• identify information associated with a target profile required to be enabled, and
• send, 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;
• and
• a baseband component configured to:
• in case that the refresh flag indicates that the refresh of the target profile is required, receive, from the eUICC, a second message to trigger the refresh of the target port, and
• after receiving the second message, send, to the eUICC, a terminal response message, or reset the target port.
