Buying and managing top-ups

You can top-up online at any time – you'll just need a credit or debit card registered to a UK address.

Start by logging in to the Three Pay As You Go app or your account. Head to the Top-up screen, hit top-up by card and choose the amount you want to add. Then select a payment option from your list of registered cards. If you haven't registered a card yet, you can add one at any time.

Once the payment's gone through, we'll send you a confirmation message to let you know.

With card Top-ups, you can top-up any Three number. So, check out 'top-up another number' below to top-up for your family or friends.

Short on time? With Buy again, you can top-up in seconds by getting the last Top-up or Data Pack you bought.

Just log in to the Three Pay As You Go app or your account, go to the Top-up screen and hit Buy again. Then choose a payment option from your list of registered cards. If you haven't registered a card yet, you can add one at any time.

To set up a Top-up Auto-renewal for when your credit is low, log in to the Three Pay As You Go app or your account and go to the Top-up screen. Hit Set up Auto-renewal, select top-up your cash credit when it gets low, then choose the amount you want to automatically top-up each time.

Now set the balance that triggers your Top-up – this has to be lower than your current credit balance. Then select your payment card to finish. If you haven't registered a card yet, you can add one at any time.

For a Top-up Auto-renewal by date, log in to the Three Pay As You Go app or your account and go to the Top-up screen. Hit Set up Auto-renewal in the menu, then select top-up credit on a set day and choose the amount you want to regularly top-up. Now set the date you want your Auto-renewal to start and whether you'd prefer it Weekly or Monthly. Then select your payment card to finish. If you haven't registered a card yet, you can add one at any time.

For any months that end before your regular Top-up date, your credit will land on the last day of the month instead. For example, if you pick the 31st of each month, in February your Top-up will kick in on the 28th.

To automatically top-up a Data Pack, start by logging in to the Three Pay As You Go app or your account and navigating to the Top-up screen. Hit Set up Auto-renewal, then select Get a Data Pack on a set day. If you have an active Data Pack, simply check the details on screen and, if you're happy, select Set up Auto-renewal.

If you don't have an active Data Pack set up, pick one from the list and hit Choose this Data Pack.

Set the date you want it to kick in, then select your payment card to finish. If you haven't registered a card yet, you can add one at any time.

If your regular Top-up date falls after the end of the month, your credit will kick in on the last day of the month instead. Say you pick the 31st of each month, in February your Top-up will land on the 28th as it's a shorter month.

If you're feeling generous, you can top-up your friends or family using a voucher or a card.

Start by hitting top-up another number on the Top-up screen and entering the number you want to top-up – this has to be a valid New Pay As You Go account on Three.

To top-up with a voucher, select Use voucher, choose the Top-up amount, and then enter your unique 16-digit code.

Or to pay by card, select top-up by card, choose the amount, and select a payment option from your list of registered cards. If you haven't registered a card yet, you can add one at any time.
