How to change your voice mail message????10 points.?

I have the T-mobile SAMSUNG gravity. I have a voice message that is like a year old and how do you change it? thanks|||After you access your Voicemail and get through all of your messages you should have an option called personal option. IF it doesn%26#039;t automatically promt the menu for that, try pressing # on your cell. From there, like I said, should be an option for personal options (such as greetings). From there it will prompt you and just follow it through. Hope this helps. :)
