Add-ons are an enhanced version of Pay As You Go designed to offer better value for your money. Instead of simply using your credit to pay for usage you get a bundle of minutes, texts and data to use within 30 days.
If you're buying an add-on you'll first have to top-up and will then be able to convert your credit into an add-on.
In addition to the add-ons listed above there are also a few extra add-ons available:
Yes. Add-ons can be combined where applicable. For example, you might have both a Three-to-Three add-on (giving you 3000 Three-to-Three minutes) and an All In One 10 add-on (giving you 1GB of data, 3000 minutes and 3000 texts).
In this case your Three-to-Three minutes would be used when calling someone else on Three, while your other allowances would be used the rest of the time.
Yes, if you have both an add-on and some ordinary credit the allowances from the add-on will be used first.
Add-ons don’t cover you making an international call, using your allowances abroad outside of Go Roam locations, using a text message shortcode service or calling a special number.
If you have a second add-on queued then this will be activated automatically. If not, Three will send you a text when you’ve used up 80% of your add-on and another when you’ve used it up completely, so you’ll know you need to buy another or top up.
Yes, although Three recommends doing so before you leave if possible. If you do need to top-up when abroad you’ll need to use a debit or credit card, as you won’t be able to buy a voucher. And remember, add-ons only work in Go Roam locations.
Trouble topping up? If you’re using a credit or debit card make sure it’s registered at the same address as you’re registered at Three with, that it hasn’t expired and that you’ve entered the security code correctly. Also, be sure you’ve got at least £10 in your account.
Issues with vouchers? Double check you’ve entered the correct voucher number and if all else fails turn your device off and on again.
No credit in your account? If you’ve topped up but can’t see the credit, wait an hour just in case there’s a delay. Or try turning your device off and on again.
Still no luck? If none of the above has helped you can always give Three a call on 333 from your Three phone for assistance.
