Through the App Store, you download and install programs on your Apple iPhone. When updates to those applications are available, the App Store notifies you and prompts you to download the latest versions. If you are out of range of a Wi-Fi connection when the App Store begins downloading an application, and you don't want to use up your limited cellular data allotment for the download, pause the download and resume it at a later time when your iPhone can access the App Store through a Wi-Fi connection.
Tap on the "App Store" icon from your iPhone's home screen.
Navigate to an app and tap "Install" or go to the Updates tab and tap "Update" next to one of the apps with an available update.
Use the on-screen keyboard to enter your iTunes account password and then tap "OK."
Locate the icon of the app that is currently downloading or updating and tap on it once. The word "Paused" appears underneath the icon.
Tap on the app's icon again when you are ready to resume the download or update.
