In a method of storing directory information in a cellular radiotelephone, the cellular radiotelephone system is provided with a network directory database including a plurality of telephone numbers. The user is prompted for the input of search criteria, and the input search criteria is accepted. A search request data signal is generated in response to the input search criteria, and this signal is sent to the cellular system. The network directory database is searched for a match with the search criteria, and one or more telephone numbers can be identified. These telephone numbers are returned to the radiotelephone and stored in a memory of the radiotelephone. This method eliminates the need to interact with a directory assistance operator and reduces the time of connection between the radiotelephone and the cellular system.
