Thee Home Phone Prepayment Outside Included Value is a pre-payment kept on the account for charges outside or in excess of your plan's included value. If your POIV (Prepayment Outside Included Value) goes below $10, we will automatically top up an amount to make it $20 again.
We've configured the system to notify you (or other customers on the same plan) that once the Home Phone Prepayment Outside Included Value has dropped below $10, we will automatically debit the account to restore the required balance of $20.00. Your internet will not be affected in the event that the pre-payment goes below the $10.
