IOS – Does send last location work with location services off

Apple works very hard to conserve battery life, and determining location, no matter if it is through GPS, cellular, or wifi connections takes extra battery. The arrow displays any time a 3rd party app requests your location. For instance, when you open Maps, the arrow will likely turn on because Maps needs to pinpoint where you are. The arrow may also turn on for system level locations services (settings can be adjusted in Settings > Location Services > System Services), and depending on your settings, the arrow may or may not appear for that.

As for Location Services being on or off, you can set that in the settings (Settings > Location Services), but if you see the arrow, it is likely on already.

The arrow only appears when location services are active, and may or may not show when it is just on.

The only thing that matters on iOS 7 is whether you have fine my phone enabled. Also, you can't turn off location services when you have find my phone active.

If so, you can't get iTunes or the device to erase itself unless you enter the password for iCloud account that is enrolled.

If you do factory erase it, it still won't re-activate unless the iCloud password is entered. So, to answer your question - location services is likely not re-enabled since the device lock prevents activation of the OS and opting in to location services before the wipe. It would either require access to the source code or servers from Apple to know if location is tracked in is case, but my intuition is no.

If you enable lost mode, that locks the device, but it still is traceable and can be located. Just as if you didn't enter lost mode.

If you erase the device, that removes the data and tracking ability once it connects to the Internet and receives the self-destruct message. It still displays the lost message, but you can't track it.
