Check your data usage on iOS

Although you may have downloaded an app or two to check how much data you’re using online, there’s a way you can tell by looking in the iOS stats themselves.

To do so, open the Settings app, then head to the General tab, and then scroll down to the “usage” option.

There, you’ll be able to see how much call time you’ve used, as well as data usage statistics. There’s even an option to reset them so you can measure how much you’ve used in a certain time.
