for iOS 5.0 software

Installing the SIM card
If you were given a SIM card to install, install it before setting up iPhone.
Important: A SIM card is required to use cellular services when connecting to GSM networks and
some CDMA networks. An iPhone 4S that has been activated on a CDMA wireless network may
also use a SIM card for connecting to a GSM network, primarily for international roaming. Your
iPhone is subject to your wireless service provider’s policies, which may include restrictions on
switching service providers and roaming, even after conclusion of any required minimum service
contract. Contact your wireless service provider for more details. Availability of cellular capabilities
depends on the wireless network.

Setup and activation
To set up and activate iPhone, turn on iPhone and follow the Setup Assistant. The Setup Assistant
steps you through the setup process, including connecting to a Wi-Fi network, signing in with or
creating a free Apple ID, setting up iCloud, turning on recommended features such as Location
Services and Find My iPhone, and activating iPhone with your carrier. You can also restore from an
iCloud or iTunes backup during setup.
Activation can be done over a Wi-Fi network or over your carrier’s cellular network (not available
in all areas). If neither are available, you need to connect iPhone to your computer. See the
following section. If you don’t have a SIM card installed (for GSM networks), iPhone must be
connected to a Wi-Fi network, or to your computer with iTunes open, in order to complete
activation. In areas where you have a choice of carriers, the SIM card must be installed to
complete the initial activation.
Connecting to the Internet
iPhone connects to the Internet whenever necessary, using a Wi-Fi connection (if available) or
your carrier’s cellular network. For information about connecting to a Wi-Fi network, see “Wi-Fi” on
page 143.
Note: If a Wi-Fi connection to the Internet isn’t available, certain iPhone features 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, see
“Network” on page 148.
