Add-ons are a great way to get more for your money. Convert your credit into bundles of data, calls or texts at the best value. Converting your credit is quick and easy. You can grab one as soon as you top-up, or come back at any time to check our great value Add-ons.
How to buy.
The Three app.
The easiest way to buy Add-ons is through the Three app. You don't even need any data, just a network connection.
You can also use the app to track your usage, view your bills and find out when you can upgrade or change your plan.
You can also login to your My3 account to buy an Add-on. Just visit the link below to get started.
If you're on a Pay Monthly plan, your Add-on will expire when your monthly allowance is refreshed.
If you're on Pay As You Go, your Add-on expires 30 days from the date of purchase. When you've used up your Add-on, we'll send you a text to let you know and you can decide whether you want to purchase another.
Is there anything Add-ons don't cover?
Add-ons don’t cover all types of services. For example, they won't work abroad if you're travelling to a country which isn't a Feel At Home destination. We recommend that you keep your account topped up with some extra credit in case you need to:
Make an international call
Use your device while roaming in a country which isn't a Feel At Home destination
Use a text message shortcode service
call a special number
If you do use these services, the cost will be taken out of your top-up credit. The cost of all other calls will be taken from your Add-on allowance.
How does combining Add-ons work?
You can have more than one Add-on at a time. For example, if you’re on Pay As You Go on Three you can use our Three-to-Three Add-on together with the All-in-One 20. That way you can call friends and family on other networks with your All-in-One allowance and you’ll still have 3000 minutes to talk to other people on Three.
If you’ve bought an Add-on and still have some credit left in your account, the Add-on allowance will be used before the credit top-up. For example, you get 10MB of internet allowance free with every top-up. You can still use the internet once that allowance runs out but we’ll use your credit to pay for it.
We’ll send you a text to let you know when you’ve used up 80% of your Add-on allowance. When your Add-ons have completely run out we’ll send another text to let you know that it’s time to top-up.
