What you choose is what you get. Your bill won't have any surprises, because our plans don't have any hidden charges or automatic data top-ups. You're in charge.
If you do run out of data, you'll be able to add extra data add-ons one-at-a-time in the add-ons area of your account. We have two data add-ons available, a 2GB add-on for $10 or a 5GB add-on for $25.
