How do I buy additional data bundles

Help and Support > Billing & Payments > Data limits & usage
If you’re getting close to your data limit, we recommend logging in to the customer portal to buy an additional data bundle. These are a lot better value than the automatic charges for going over your limit. Alternatively if you find you’re always reaching your data limit, why not think about upgrading to one of our unlimited packages. This gives you the peace of mind to browse, stream and chat as much as you like, without getting charged extra.
