Assuming that you have voicemail oh your service plan with this phone, there should be a voicemail number that you call to get your messages, Many phones assigen the number 1 for this function, but if in doubt, ask your service provider.

Got instructions for the store where we bought it.

for "guess" it is the last 4 digits of your phone number, its all in the rumor book thingy

Many people confuse voice mail with answering machines. Most of the time if you have voicemail that is provided by your phone company you will hear a stuttered dial tone when you pic up the reciever. If this is what you hear you should call the service provider and they will explain how to retreive your messages and delete the old ones. Are you able to listen to you messages? If you have voice mail, you do not need the answering machine turned on on your phone.

ask your service provider to erase your voicemail on the phone then add it back again and clearing all msgs

Press the hard button which you normally use for switching profiles this will enable the keypad which you can then press the relevant number to delete your voice mail

There isn't a way to disable voicemail cause it automatically fowards the call.
