for them to track you, and it does NOT need to even be turned on.
All location information comes from a (cellular) tower. The towers the phone connects to can determine
your location. Not as good as GPS,
but less than a city block most of the time, even with no help from the phone. In addition, cell phones sold since 2002 in
the US are
required to have some level of location capability that is supposed to be
accurate to 150 meters 95% of the time. Yes,
even dumb phones, and yes, even without GPS
