In-Depth Information
Airplane mode:
Airplane mode should be enabled when you fly. It turns off all of
the wireless features of your iPad — the cellular, 4G, 3G, GPRS (General Packet Radio Ser-
vice), and EDGE (Enhanced Datarate for GSM Evolution) networks; Wi-Fi; and Bluetooth
— so you can enjoy music, video, games, photos, or any app that doesn't require an Internet
connection while you're in the air.
To enable Airplane mode, tap the Settings app and then tap the Airplane Mode switch so it
says On (or tap the Airplane Mode icon in Control Center — see Chapter
14
— so it lights
up).
There's no need to enable Airplane mode on flights that offer onboard Wi-Fi. On such flights
it's perfectly safe to use your iPad's Wi-Fi while you're in the air (but not until the captain says
so).
The icon shown in the margin appears on the left side of your status bar whenever Airplane
mode is enabled.
Disable Airplane mode when the plane is at the gate before takeoff or after landing
so you can send or receive e-mail and iMessages.
LTE ( Wi-Fi + 4G models only):
This icon lets you know that your carrier's 4G
LTE network is available and your iPad can use it to connect to the Internet.
GPRS ( Wi-Fi + 3G and 4G models only):
This icon says that your wireless carri-
er's GPRS data network is available and that your iPad can use it to connect to the Internet.
EDGE ( Wi-Fi + 3G and 4G models only):
This icon tells you that your wireless
carrier's EDGE network is available and you can use it to connect to the Internet.
