When an app needs to use the Internet, iPhone does the following, in order:
Connects over the most recently used available Wi-Fi network
Shows a list of Wi-Fi networks in range, and connects using the one you choose
Connects over the cellular data network, if available
Note: If a Wi-Fi connection to the Internet isn’t available, apps and services may transfer
data over your carrier’s cellular network, which may result in additional fees. Contact your
carrier for information about your cellular data plan rates. To manage cellular data usage,

Apple ID
Your Apple ID is the account you use for just about everything you do with Apple—including
storing your content in iCloud; downloading apps from the App Store; streaming Apple Music
content; buying music, movies, and TV shows from the iTunes Store; and purchasing books
from the iBooks Store.
If you already have an Apple ID, use it when you first set up iPhone, and whenever you
need to sign in to use an Apple service. If you don’t already have an Apple ID, you can
create one whenever you’re asked to sign in. You only need one Apple ID for everything you
do with Apple.
For more information, see .
iCloud
Safely store your photos and videos, documents, music, calendars, contacts, News
favorites and saved stories, and more in iCloud so they’re always available—even if you
lose your iPhone.
Set up iCloud. Go to Settings > iCloud. Create an Apple ID if needed, or use your existing
one. Content stored in iCloud is pushed wirelessly to your other devices where you’re signed
in to iCloud with the same Apple ID.
iCloud is available on devices with iOS 5 or later, on Mac computers with OS X Lion v10.7.5
