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.

2 Touch Settings > Wireless & networks > Mobile networks.
3 Touch Data roaming to remove the checkmark from the box. With
Data roaming unchecked, you can still transmit data with a Wi-Fi
connection. See “Connecting to Wi-Fi Networks” on page 61.
To limit your data connection to 2G networks
You can extend your battery life by limiting your data connections to
2G networks. 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.
