Steps to enable or disable airplane mode on your HTC EVO 4G
Airplane mode disables your device's ability to send or receive any type of wireless transmission.
If airplane mode is turned on, your HTC EVO™ 4G can't connect to the Sprint network.
Note: You can re-enable Wi-Fi and connect to a Wi-Fi network while Airplane mode is enabled.
