Is It Possible to Pay by Direct Debit?

You can pay for your prepaid and plan credits by direct debit.

You can manage your payment method from the main drop-down menu, which is located at the top right of your screen. From here navigate to Account > Billing. 

You can also manage your payment method in the second step of the booking process.

Once you choose to place an order, a pop-up will open that includes the option of modifying your payment method.
