What if device says offline when using find my iPhone

What if your device is off or offline?

If your missing device is off or offline, you can still put it in Lost Mode, lock it, or remotely erase it. The next time your device is online, these actions will take effect. If you remove the device from your account while it's offline, any pending actions for the device are canceled.
