Why are location services not working for find my iPhone?

I use find my iPhone to make sure ik where my younger cousin is at and is okay but today it said location services off but my Cuzzin never messes with the location part of their phone so why is this happening?

There are several possible reasons, low battery, phone is off, no or very low signal where the phone is, inside a build with poor cell phone reception, your cuz has finally figured out how to MESS with the phone and turn off the location.

Your cousin learned how to turn it off.

Maybe he/she did this time and/or someone else did.

Also you could & probably should be using Find My Friends for that purpose (with their knowledge of course).

Reboot the iPhone and try again. This happens to me occasionally.
