Make a payment in advance
You can make a payment in advance, that is, add an amount of money on your account to cover charges for future bills. The minimum payment is $10. However, if your outstanding balance is less than $10, the minimum payment is the amount of your outstanding balance.
Making a payment using a card assigned as a primary or backup card charges the outstanding balance on your account.
To make a payment in advance:
Sign in to Fiber using the email and password you use for your Fiber account. Your Account page appears.
Click Manage Bill; then click Make a Payment. By default, the amount you enter is applied to your primary payment method.
If you prefer to associate the charge with another payment method, or want to add a new card or bank account to associate the charge with, click the carat next to the selected payment method and choose the desired method.
Enter the amount (a minimum of $10) you want to pay; then click Make a Payment.
Confirm your payment details and then click Make Payment to complete the transaction. Your account balance is updated as soon as the payment is authorized.
