Guide How to Top Up (PAYG) - your payment is used on the payment date to cover your next month's usage? And if you are on a Pay As You Go: Introducing "Rolling Plans" your balance is only used for out-of-tariff charges (eg calls to non-UK numbers) as the balance top up comes off the card you have associated with your account, @st3llam4n.
