If you're topping up your tablet, Mobile Broadband, or dongle, you'll need to top up using My3 or on the web.
Top up, buy Add-ons, and access exclusive offers – even while abroad.
You can top up a few different ways online:
Log in to My3 to register a credit or debit card for quick future Top-ups.
Make a one-off card payment online.
Top up using a pre-purchased voucher.
You can top up a friend’s account via your My3 account.
You can also top up without needing to register for an account, but you’ll have to re-enter your card details each time.
If you're a phone customer, you can call 444 free from your Three phone to top up over the phone.
