How To Turn Off The New iPhone Feature That Will Send Your Bill Skyrocketing

Apple recently released iOS 9, implementing a new feature which is costing people with limited data plans hundreds of dollars.

"Wi-Fi Assist," which is on by default, will automatically switch you to 4G if it thinks the WiFi you're using is too slow. If you're on a limited data plan, that's bad news.

Here's how to turn if off:

1. Open your settings.

2. Choose "Cellular."

3. Scroll all the way to the bottom, to find "Wi-Fi Assist." Finally, touch the button to turn it off.

And that's it - we just saved you hundreds of dollars - you're welcome.
