## Abstract

The disclosure relates to a 5G or 6G communication system for supporting a higher data rate than a 4G communication system such as LTE. An embodiment of the disclosure provides a method and an apparatus for determining a scheme of accessing an ISD-R corresponding a profile management module in an eUICC in a terminal (a modem or an LPA) during terminal-card initialization. In addition, an embodiment of the disclosure provides a method for determining, by an LPA, a scheme of access an ISD-R to be used by the LPA, with reference to a scheme determined during terminal-card initialization or a pre-configured scheme, and transferring a message to an eUICC. In addition, an embodiment of the disclosure provides a method and an apparatus for configuring, by an LPA, different profile management messages according to determined ISD-R access schemes, and perform transferring through a selected ISD-R access scheme.

## Claims

### Claim 1

A method performed by a terminal in a wireless communication system, the method comprising:
transmitting, to an embedded universal integrated circuit card (eUICC) in the terminal, a command for configuring at least one embedded subscriber identity module (eSIM) port, the command including first information, wherein the first information includes at least one multiple enabled profiles (MEP) mode supported by the terminal, wherein the at least one MEP mode is included in MEP modes which are associated with an issuer security domain-root (ISD-R) selection and an eSIM port selection;
receiving, from the eUICC, a response including at least one of second information and third information as a response to the command, wherein the second information identified based on the first information includes information for an MEP mode jointly supported by the terminal and the eUICC, wherein the third information includes one or more MEP modes supported by the eUICC, wherein the one or more MEP modes are included in the MEP modes; and
identifying, an MEP mode based on the at least one of the second information and the third information.
