How can I top up?
We've listed all the ways you can top up below. Don't forget – you can check your credit balance at any time by dialling 1745.
Instant Top Up
The quickest way to top up is by using our Instant Top Up Service. All you need is your phone number and a debit/credit card.
You can top up easily by logging into your My3 account or using our My3 app. You can also set up a scheduled top up on your My3 account, which means you'll never be stuck for credit.
Dial 1744 from your Three phone and follow the instructions to top up.
If you've registered a card with us previously, just text TOPUP, the amount you want to top up by, and the last 4 numbers of your registered card to 50100 (e.g. TOPUP 20 1234).
You can purchase a Three top up voucher from your nearest Three store, or from a range of retail outlets throughout Ireland. You can then use your voucher to top up by logging into My3, calling us on 1744 or texting TOP UP and the voucher code to 50272.
If you're a banking customer of AIB or Bank of Ireland, you can top up your Three phone via your online banking service.
