Not sure exactly what you mean - do you mean that when people are calling you they're being told that your voicemail is not set up?
OR
There isn't a number listed to check your own voicemails?
If it's either of these above try dialing *86 on your phone - that is both the number to retrieve your voicemails and to set it up also.
If it's a different problem if you can clarify a little more then I'm sure we can all help you out
Hope this info was a wee bit helpful if either of those were your problem. If not I'm sure others will be able to help you like they've helped me too.
Sarks.
