You can change plans at any time. When going from Visible to Visible+ you will pay a prorated amount based on the difference in what you pay for basic and the $45 plus plan. This depends on where in your billing cycle you are. The upgrade takes effect immediately. When going from Visible+ to Visible the change will take place at your next billing cycle and no refund will be given. If you are on a promo price, you may or may not keep that price after you change plans.
