What is an Add-On and how do I buy one?
An Add-On is additional data, minutes, text or minutes for international calls that you can add onto your current monthly plan. To add an extra to your mobile plan, use this link:
Add-Ons are useful if you’re running low on monthly data or minutes, or if you want to add a feature, such as international calling, that’s not part of your current monthly plan.
Buy an Add-On when you need more data, minutes, text or minutes for international call coverage than your current monthly plan allows. Add-Ons take effect immediately.
How long does it take to activate an Add-On? How long does it last?
Add-Ons are active immediately. They’re valid until the end of your next payment cycle.
In other words, if there are 10 days left on your current payment cycle, your Add-On will be valid for approximately 40 days.
