Connecting to mobile networks
When you assemble your phone with a SIM card from your wireless service provider
(see “Installing the battery, SIM, and microSD card” on page 18), your phone is
configured to use your provider’s mobile networks for voice calls and for transmitting
data.
Your phone is configured to work with many mobile carriers’ networks. If your phone
does not connect to a network when you insert a SIM card and turn it on, contact your
carrier to obtain the details of its access point name. See “To edit or create a new
access point” on page 71.
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 between charges. You can also configure your phone to access a
different set of networks entirely, or to behave in special ways when roaming.
The icons in the Status bar indicate which kind of data network you’re connected to
and the voice and data network signal strength.
When you’re connected to slower networks, you may want 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 68.
To determine what network you’re using
1 Press Home , press Menu , and touch Settings to open the Settings
application.
