Even with gps off, they can get rudimentary location data based on pings to cell towers. It's not pin point obviously, but it roughly tells how many people are in a given area with a phone on them, smart or dumb.

I don't know if things have improved, but GSM-based positioning has accuracy of +/-2.5km.
