Installing the SIM card

If you were given a SIM card to install, install it before setting up iPhone.


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.
