Sometimes. But most cell phones have GPS unless someone has accidentally used a stereo loupe and minature soldering iron and accidentally disabled the GPS receiver chip. Accidentally, of course. You can accidentally get instructions off the web.

Any Android phone has Google Maps with Latitude, which can easily be enabled and joined to another Latitude user. Once visible to each other, you can remotely turn on real time tracking. Mostly it will identify the nearest cell phone tower, giving you only a general location, if it is in a purse or pocket. Out and in use, it will pin down which side of a street a person is standing on.
For those who accidentally disabled the GPS chip, the passive location doesn’t depend upon the GPS, it reads the cell phone tower (which is a known location) as well as those mapped wifi hotspots, which can easily pin someone without GPS down to a two block area.
Which is a complete waste of time. Cell tower location usually provides enough damning information.
Seems like a lot of techno-work for an accident!! I know one Mom in our neighborhood that has a GPS on her teen son’s phone. Not sure how it works (I am technology deficient) but I think I remember that she can pinpoint where he is at all times. Maybe her son has given her problems or concerns. Not sure... I seem to always know where my teen boy is located (school, football practice or in front of the fridge).
