Disable data when roaming

With Data roaming unchecked, you can still transmit data with a Wi-Fi connection.See “Connecting to Wi-Fi networks” on page 61.

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.
