Can I only register for Jott Voicemail?
You sure can, you do not need to sign up and pay for Jott, Jott Pro or Paygo to use Jott Voicemail. If you are not currently a Jott account holder, you can sign up for a Voicemail account here. If you already have a Jott account you can add a Jott Voicemail plan by going to the Billing section of the My Account page and adding a Jott Voicemail plan.
