That means the phone is powered off.

This also explains why your device is offline and what you should do;

If your iPhone, iPad, or iPod touch is lost or stolen - Apple Support

especially the section:

What if your iOS 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 will be cancelled.
