Connecting to Mobile Networks
When you buy your phone and sign up for service, 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. You can also configure your phone to access a different
set of networks entirely, or to behave in specific ways when roaming.
Connected to the 4G network (LTE).
Connected to the EVDO network (EVDO revA).
Connected to a 2G network (1x).
Signal strength - more bars that are lit, the stronger the wireless
signal.
Connected to another wireless service provider's network
(roaming).
The icons in the Status Bar indicate which kind of data network you're
connected to and the network signal strength.
When 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.
To disable data when roaming
You can prevent your phone from transmitting data over other carriers'
mobile networks when you leave an area that is covered by your carrier's
networks. This is useful for controlling expenses if your cell plan doesn't
include data roaming.
1. Touch the Applications Key
Mobile networks > Data roaming.
2. Touch Data roaming to remove the checkmark from the box. With Data
roaming unchecked, you can still transmit data with a Wi-Fi connection.
