On the road
Whenever you leave your house or work I would recommend turning off WiFi and Bluetooth on your mobile phone. Although your phone provider, Google and other services that are enabled on your phone are tracking you, there's no reason to permit stores, agencies or other facilities you visit to track you.
Also, if you are going to use a public WiFi, be sure to connect to a VPN prior to doing anything else. See the section: After boot up.
