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.

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.

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.
