How to Top Up


We’ve listed all the ways you can top up (buy credit) below. Don’t forget – you can check your credit balance at any time by checking your My3 account, or texting BALANCE to 50272. 


You must top up every 28 days to keep your plan benefits. For example, if you have moved to our 3 Prepay 20 plan, a €20 top up is required to activate your plan benefits (unlimited texts, unlimited Three calls, All You Can Eat data and more). Your account will then be debited €20 to activate your plan.


Please note:

  • If you top up by your required amount before 28 days is up, your plan will re-activate and your remaining allowances at the time of top-up will not carry forward.
  • After topping up, your credit will be valid for 180 days. After 180 days, the credit will expire.

To top up via Alexa, follow the below steps:

  1. Start by adding the Three Top Up skill to your Alexa enabled device and linking your My3 account.
  2. Now try saying “Alexa, ask My3 to top me up.”
  3. Alexa will then ask you what card you want to use. Reply “Use my default card.”
  4. Alexa will ask you how much you’d like to top up by. Tell Alexa your desired top up amount, for example “€20”.
  5. Next Alexa will call out your card details to confirm and ask if you wish to proceed.
  6. Reply “Yes” if you wish to proceed or “No” to cancel the transaction.
  7. If you reply with “Yes” then Alexa will confirm by saying “Thank you, your transaction was successful”. That's it!
