A method for managing user service profiles by an entity for managing the profiles of user services in a nominal network, before dispatching to a third-party entity a service profile of a the user. The method includes determining whether the third-party entity is in a visited network different from the nominal network; if so, determining, on the basis of the service profile of the user recorded in the profiles management entity, if the user has at least one mark associated with an IN originating service; if so, checking to determine whether there exists an intelligent network agreement between an operator of the nominal network and an operator of the visited network and if relevant the nature of the agreement; and dispatching, to the third-party entity, a service profile of the user determined as a function of a type of the service and of the result of the checking.
