The invention provides a system and method for profile synchronization. The profile synchronization system includes a web server, a synchronization server, and one or more mobile terminals. The web server includes subscriber accounts each containing a subscriber profile and a profile matching table, identifies, when a subscriber profile is changed at the web server, a subscriber profile in the synchronization server corresponding to the changed subscriber profile using the profile matching table, and transmits the changed subscriber profile to the synchronization server. The synchronization server includes a database to store subscriber profiles of the one or more mobile terminals in synchronization with the synchronization server, updates, when a changed subscriber profile is received from the web server, the corresponding subscriber profile, and transmits the changed subscriber profile to the one or more mobile terminals in synchronization. Each of the one or more mobile terminals updates the corresponding subscriber profile for synchronization when a changed subscriber profile is received.
