"Adding credit to call is easy. Log in to your account and, on the Snapshot page, click the “Add Credit” button or choose Add Credit directly from the top menu. In order to buy calling credit, you need a valid credit card. We accept major credit cards and PayPal (you can also use most prepaid debit cards in our system). After adding your payment data via our secure system, you will be able to add credit manually... or set your account to automatically recharge via credit card when it gets below your selected value. Note: QuickCall is a prepaid service. So, you must have credit in your account in order to make cheap international calls."
