Connecting to mobile networks
Your phone can connect to a variety of networks and devices, including mobile networks for voice and data transmission, Wi-Fi data networks, and Bluetooth devices, such as headsets. You can also connect your phone to a computer, to transfer files from your phone’s SD card, and share your phone’s mobile data connection via USB or as a portable Wi-Fi hotspot.
Connecting to mobile networks
When you assemble your phone with a SIM card from your wireless service provider, 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.
To determine what network you’re using press Menu and touch Settings to open the Settings. Touch Wireless & networks > Mobile networks > Access Point Names. The name of the wireless service provider you’re currently registered with is selected in the list.
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.
Press Home , press Menu , and touch Settings, to open the Settings application. Touch Wireless & networks > Mobile networks and uncheck Data roaming. With Data roaming unchecked, you can still transmit data with a Wi-Fi connection.
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. Touch Wireless & networks > Mobile networks and check Use only 2G networks.
