How to turn off the iPhone setting that’s secretly sucking all your data

If you have an iPhone, you might have already checked out iOS 9, Apple’s latest operating system.

While super nifty, there’s something you should know if you don’t want your phone bill to go through the roof after installing it. With the iOS 9 update came a little feature called “Wi-Fi assist,” which will begin sucking away at your phone’s data plan when your wireless internet connection starts to get spotty or weak. In other words, you could be digging into those precious megabytes without even realizing.

Unless you have an unlimited data package, you do not want this feature. Repeat: You do not want this feature on your phone.

While we can’t account for Apple’s thinking here, the good news is, they made it super easy to turn off. Here’s how:

1. Open up the “Settings” app on your phone
2. Choose “Cellular”
3. Scroll all the way to the bottom (this is why nobody sees this feature)
4. You will see an option called “Wi-Fi Assist.” Turn it off
5. Use your Wi-Fi connection without fear
