Can’t Set Hard LimitsiOS 9 doesn’t allow you to set hard limits on data usage for individual apps, only to turn data off completely.

Additional Information

Let’s talk tips and tricks. First off, if you’re dismayed by the amount of data an app is using, consider using it only when connected to Wi-Fi. Another pro tip? Regularly reset your statistics. There’s an option to “Reset Statistics” at the bottom of the Cellular menu which you can use to start tracking your data usage afresh every billing cycle. This makes it easier to keep an eye on your monthly usage without old data clouding the picture.

What if you notice an app is using data even though you’re not actively using it? This could be due to background app refresh, which allows apps to update content in the background. You can turn this off either completely or for individual apps in the General settings. Remember, it’s all about taking control of your iPhone experience and ensuring that you’re not spending more on data than you need to.
