iCloud: online
This article has been archived and is no longer updated by Apple.
An iOS device is online if it’s turned on (with or without a passcode lock) and connected to a data network, such as EDGE, 3G, 4G, or Wi-Fi. A Mac computer is online if it’s turned on and connected to the Internet via Wi-Fi or Ethernet.
If a device is online, a green dot 
appears beside the device in the My Devices list.
