SIM card
If you were given a SIM card to install, install it before setting up iPhone.
Important:
A Micro-SIM card (iPhone 4s) or a Nano-SIM card (iPhone 5 or later) is required
to use cellular services when connecting to GSM networks and some CDMA networks. An
iPhone 4s or later that’s 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.
