Your iPhone is capable of connecting to the Internet with both cellular and Wi-Fi networks. Once you have connected to a Wi-Fi network with your iPhone, you will be able to connect to it whenever you are within range of that network.
But when you are not connected to a Wi-Fi network, you are using cellular data to connect to the Internet.
Whether this is by downloading mail, streaming from YouTube or checking Facebook, you probably have a cellular plan that provides you with a certain amount of data. You can check which apps are using the most data on your iPhone by following our guide below.
Checking Cellular Data Usage for iPhone Apps
The steps below were performed on an iPhone using the iOS 7 version of the operating system. If you are using an earlier version of iOS, these steps might not work for you. You can learn how to update to iOS 7 here.
Step 1: Tap the Settings icon.
Step 2: Select the Cellular option.
Step 3: Scroll down to the Use Cellular Data For section. The amount of data used for the current period is displayed under the name of the app.
You can reset the statistics for your current period by scrolling to the bottom of the screen and tapping the Reset Statistics button, then confirming that you want to reset the statistics. This can be a good idea to do manually at the start of each billing period so you can see how you are using your data.
Now that you know how to view which iPhone apps are using the most data, you can use this information to determine whether or not you need to prevent their cellular network access.
You can also use this menu to allow or prevent specific apps from using cellular data. This is great if you have an app that is using a lot of your data, but that you can use effectively when you are only connected to a Wi-Fi network.
