Yes! The advantages of this are (i) no annoying reminder emails, and (ii) the security of knowing that you’ll never accidentally run out of credit. To set up recurring billing, go to My account > Billing, and top up your prepay balance as usual, using a credit card. After you have paid and verified your card, you will see an options screen. Under ‘Balance’, choose the billing options you want. For example: Automatically top up my balance by $50 every time it drops below $5, charging my stored details (up to a maximum of $250 per month). Sorry, recurring billing is not currently available for customers using PayPal. Please note that you will be billed 7 days in advance of your subscription being renewed.
