I vaguely remember rumors (or maybe it was used in a few court cases by the FBI), where carriers would turn on the microphones of 2G dumb phones remotely and silently. So your dumb phone probably has the same issue.
Carriers also keep records of where subscriber devices have been, so even if your phone doesn't have GPS, the carrier has cell tower triangulation logs of the device too.
ISPs such as comcast also save your browsing history to run their advertising networks, so that is also recorded somewhere too. And if/when net neutrality goes away completely, they might just sell that info too:

Whats even worse about ISPs doing it is how you usually have no other choices and it's your complete traffic stream!
