Cellular data and location

What are your thoughts on the telecommunications company’s themselves who have cellular data from internet traffic activity and also (GPS off) geolocation data from cell phone tower triangulation?

How can this addressed:
1.) policy making
2.) education/informed consumer
3.) off the grid (turn off the cell completely, really truly turned off - equivalent of battery removal) mode if a person truly wants no tracking for a period of time.

Seems like a similar question has been discussed here recently.
