6 Use Wi-Fi in Airplane Mode

When traveling abroad, I am keen on also turning on Airplane Mode in addition to toggling Data Roaming off.
The Airplane Mode setting suspends radio-frequency signals from transmitting to or from your device.
Airplane Mode can easily be accessed by swiping up on the Home screen to reveal the Control Panel, then tapping the airplane icon to turn it orange.
You can still use Wi-Fi and Bluetooth while in Airplane mode. To use Wi-Fi, tap the Wi-Fi icon and then connect to a network like normal. The same goes for Bluetooth. You will have to turn both of these on, because Airplane mode turns them off by default.
Just be careful not to accidentally turn off airplane mode, as you will begin incurring carrier charges.
