What is a Data Pack?
Buying a Data Pack is an easy way to make your money go further. Pick the amount of monthly data you need and get unlimited calls and texts included.
You can only have one active Data Pack at a time. To make sure you’ve got the data you need every month, try an Auto-renew Data Pack.

Get more with an Auto-renew Data Pack
Get extra data on us with an Auto-renew Data Pack. They work like a subscription, giving you the same amount of data every month unless you cancel. But they’re commitment-free – you can cancel at any time.
