A method and an apparatus for installing a profile in a terminal including a universal integrated circuit card (UICC) corresponding to a smart card security module, which is inserted into a mobile communication terminal and then used are provided. More particularly, a method and an apparatus for remotely installing or removing mobile communication subscriber information in/from a profile of a terminal are provided. The terminal can remotely download the profile from a network server (subscription manager data preparation (SM-DP) or subscription manager secure routing (SM-SR)) without any change in a mobile network operator information technology (IT) system interface rather than downloading the profile of the terminal by the network server.
