    Abstract: The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. The disclosure relates to a method and an apparatus for installing and managing an eUICC profile. The method comprises: receiving, from a terminal through the transceiver, a message comprising capability information indicating whether a device change function is supported; determining that the terminal supports a device change, based on the capability information indicating that the device change function is supported; and transmitting, to the terminal through the transceiver, metadata comprising a device change configuration based on a determination that the terminal supports the device change.
