Reset Voicemail Number 10.3.1

After updating my Z10 to 10.3.1 on Verizon (via Sachesi) the other day, I accidentally put in the wrong voicemail number and, unfortunately, it seems there is no easy way to reset it. I browsed through the voicemail settings (in the phone app settings) and only see an option for 'change password'. Is there a work-around that anyone has found, such as reloading a .bar or something? Or am I just going to have to reload the OS because of one oversight?

What exactly do you mean by:

I'm confused as to what you mean by this. Are you receiving voicemails for someone else's phone number instead of your own?
