Visual Voicemail is an optional application for the iPhone. In addition to providing a text version of your voice mail, it also enables you to have the Visual Voicemail icon on your iPhone home screen. Although there is no charge for this service, you have to install and activate it before use.

Step 4
Select "Install." Your iTunes password may be requested. The voice-mail application will begin downloading. Once it is complete, the icon will be displayed as "VM Viewer" on your handset. The number of messages received will be displayed on the "VM Viewer" icon.
