PhoneView's Voicemail mode requires Visual Voicemail, which will allow you to see your voicemail messages listed on the phone's screen rather than having to dial into a special number. If you don't have this feature, it's either not set up or not available from your cellular provider. If you're not sure if you have this feature available, contact your cellular provider for more info.
