Voice mail question on an old Nokia model

Please don't laugh (well, at least not too hard...)



I have a Nokia 6650d 'flip phone'. My question is: Is there any quick way to disable and enable voice mail? There are times when I'd like for it to be functional, but it would really be nice to have it 'turned off' most of the time.



Thanks in advance
