A method for synchronizing multiple database that are provided at different times is provided. As a wireless communication device ( 102 ) leaves a first region ( 104 ) and enters a second region ( 108 ), it is provided with a new preferred roaming list information ( 204 ) which may no longer be synchronized with a stored functionality extension table. Based upon information included in the new preferred roaming list information, an appropriate functionality extension table ( 214 ) that is synchronized to the new preferred roaming list is received.
