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

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.
