Last Update Date : May 16. 2018

4G Settings

Your device lets you decide how your device connects to your wireless carrier's network. To edit your device's network settings, from the Home screen, touch Menu 1 > Settings 2 > More settings > Mobile networks. If you mark the Mobile data option, your device will connect to your carrier's wireless data network.

To quickly access Mobile data, open the Notification Panel by swiping your finger from the top of the screen to the bottom, and touch the Mobile data shortcut. When the Mobile data option is enabled, the icon will appear green.

Touch Network mode to select the technology your device should use when connecting to your carrier's wireless network. Select LTE/CDMA to let your device connect to your carrier's 4G LTE data network, when it is available. Select CDMA to let your device connect only to a CDMA system. This may be needed when you are roaming outside of your carrier's network. Contact your carrier for more information on when you should use this option.
