Abstract

A wireless communication device provides for voicemail message notification and retrieval in a wireless communication system without the need for an alphanumeric display for the display of text messages on the wireless communication device. A transmitter and receiver communicate with a central message storage area containing one or more voicemail messages intended for the wireless communication device. The central message storage area transmits a voicemail message notification to the wireless communication device whenever there is a change in the number of unread messages stored in the central message storage area. The message notification includes the number of unread messages and may include a callback telephone number to retrieve the voicemail messages.
