When you enable tethering, you have options for when you can begin using the feature - and when you'll start getting billed for it. Choose from:
- Backdate - This adds the charge to your current month. Only choose this if you're close to running out of data on your plan and need more (though tethering may not help much with that, since it's often bandwidth-intensive).
- Make effective today - This puts the feature in place immediately and pro-rates the cost of tethering over the rest of your current plan month.
- Future date - This will begin billing at the start of your next month. But it means you won't be able to use tethering until then either.
Make your selection and continue.
