Abstract
The disclosure relates to 5G or 6G communication systems to support a higher data rate after 4G communication systems, e.g., LTE. The disclosure provides a method performed by a user equipment (UE) in a wireless communication system, the method comprising: receiving, by a modem from an embedded universal integrated circuit card (eUICC), a first message including at least one of information related to whether eUICC functionality is supported and information related to whether multiple enabled profiles (MEPs) are supported; and determining, by the modem, to operate with an MEP function based on at least one of the received information related to whether the eUICC functionality is supported and information related to whether the MEPs are supported. Further, various embodiments of the disclosure provide a method and device for providing a dual-SIM function even in a UE equipped with a single eUICC in a wireless communication system.
