As you probably already know, turning on “Airplane Mode” on your iPhone or iPad automatically disables all wireless communications features in a single step—cellular voice and data, Wi-Fi, Bluetooth and GPS. This is a handy—and almost necessary—feature when you’re in a situation where you’re required to turn off all transmitting devices, such as aboard an aircraft. However, you may not know that you can turn Wi-Fi and/or Bluetooth back on after entering Airplane Mode, allowing you to access an Internet connection or connect with a Bluetooth keyboard or audio device. This can be useful when aboard a flight that includes in-flight Wi-Fi, but can also be used in those situations where you may want to turn off cellular voice and data while still accessing the Internet via Wi-Fi, such as to avoid potential roaming charges when travelling abroad. Keep in mind as well that unlike traditional SMS, services like iMessage and FaceTime will work fine over a Wi-Fi Internet connection and don’t require the cellular radios to be on.
