To get started, open the Three Pay As You Go app or log in to your account. Then, go to Manage Top-ups and hit Buy Data Pack.
Now pick out the Data Pack you want. We'll offer a recommendation, but you can go for whichever one suits you best. Just hit Choose this Data Pack when you've decided.
Choose a start date, then let us know if you'd like to set up a Data Pack Auto-renewal. You can cancel this at any time, but it'll keep going until you do.
Next, tell us how you'd like to pay for your Data Pack. You can use your credit or a registered card to make the payment.
Once you've done that, you're good to go. Your allowances will kick in from the start date you chose. They'll last for 1 month or until you've used them all up (if they're not unlimited).
