1. With regards to cell phones and triangulation: turn off GPS services. I stress this to anyone with a smartphone. Not only does GPS decimate battery life, it's basically a tracker for everywhere you've been. Turn it off in your settings unless you need it (i.e. traveling).
2. With regards to landlines: either don't have one or only use yours for emergencies. Most households don't have landlines anymore. We personally don't use one, as I have a HAM radio setup on battery backup if the SHTF.
3. With regards to social media: DON'T USE IT! I live a very happy life without social media. Most people say they can't live without it, but I challenge anyone to try. It's really not that hard.
