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.
1Press Home , press Menu, and touch Settings.
2Touch Wireless & networks > Mobile networks and uncheck
Data roaming.
With Data roaming unchecked, you can still transmit data with a
Wi-Fi connection. See “Connecting to Wi-Fi networks” on
page 69.

To limit your data connection to 2G networks

You can extend your battery life by limiting your data connections to
2G networks (GPRS or EDGE). When you are connected to a 2G
network, you may want to postpone activities that transmit a lot of
data, such as sending, uploading, or downloading pictures or video,
until you are connected to a faster mobile or other wireless network.
1Press Home , press Menu, and touch Settings.
2Touch Wireless & networks > Mobile networks and check
Use only 2G networks.
