That's why it is very important to turn off GPS Location service on your phone (except for maybe "Find My Phone" then also turn off "Share My Location" as well). I would imagine this to be a safety feature to leave your GPS-disabled phone on and left in your glove box of your car if working in an area where phones are prohibited.
