Hey Ryan. Do be adviced that you sadly must have activated this tracking feature prior to the incident (device going missing) for this to be an option. You must either have activated the built-in "Android Device Manager" discussed on point number 9) here
or any other third anti-theft party app like the AVG... The device also does have to be on and with enabled data connection. It doen not necessarily have to have your SIM card in it during the tracking.
