Connecting to mobile networks
When you assemble your phone with a SIM card from your wireless service
provider (as described in “Your phone and accessories” on page 19), your phone is
configured to use your provider’s mobile networks for voice calls and for
transmitting data.
Different locations may have different mobile networks available. Initially, your
phone is configured to use the fastest mobile network available for data. But you
can configure your phone to use only a slower 2G network for data, to extend the
life of your battery. You can also configure your phone to access a different set of
networks entirely, or to behave in special ways when roaming.
The status bar indicates which kind of data network you’re connected to and the
overall voice and data network signal strength:
When you’re connected to slower networks, you may wish to postpone using your
phone for data-intensive tasks until you are connected to a faster network again, or
find a Wi-Fi network to connect to (see “Connecting to Wi-Fi networks” on
page 60).

To disable data when roaming
You can prevent your phone from transmitting data over other carriers’ mobile
networks, when you leave an area covered by your carrier’s networks. This is useful
if you chose a cell plan that doesn’t include data roaming, to control expenses.
