Does a cell phone send a gps location when you send a text message?
Yes. Whenever a cell phone is turned on, in use or not, it can be tracked on GPS. That is how many police departments can locate kidnap victims.
“Cell phones are two way radio transmitters that work by connecting to a nearby tower and exchanging data. Despite the FCC’s limitation on maximum power output of a cell phone, they are still able to connect with towers miles away at UHF frequencies and produce enough RF power to supply those fancy replacement flashing antennas with energy. Because cell phones put out a constant RF output (sometimes pulsed) they can be tracked using the tower triangulation method where the network administrators can find your precise location with their administrative network access. ”
