How Add-ons work.
Add-ons give you more for your money, but unlike credit, most are valid for 30 days.
Control your spend.
Keep track of your credit, allowances and top-up in My3, so you'll always be in control.
Find out your number.
If you want to top-up online you'll need to know your phone or Mobile Broadband number before you begin.
