Visual Voicemail may be an optional service in some countries. Contact your carrier for 
more information. 

If iPhone prompts you for your password when you tap Voicemail and you don’t 
remember your password, tap   for instructions on resetting it.

If the voice instructions prompt you, enter your voicemail password. Otherwise, wait 
until you hear any voice instruction, then end the call. After a time, Voicemail should 
become available again.

This may occur if you removed the SIM card from iPhone and replace it with another 
SIM card.
