Your service provider may have
preprogrammed your voice mail number,
if not your phone may prompt you to store
your voicemail phone number. If you don't
know your voicemail number, contact your
service provider.
Note: You can't store a p (pause), w (wait), or n
(number) character in this number. If you want
to store a voicemail number with these
characters, create a phonebook entry for it.
Then you can use the entry to call your
voicemail.
