How do I know when I have nearly used up all my data

Help and Support > Billing & Payments > Data limits & usage
We will send you emails when you have reached 80% and then 95% of your data limit. We will send another email when you have reached 100%. Additional bundles are available to buy in your customer portal. 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.
