The law in US and Canada says you can always use a cell phone for 911 calls even without a plan. One of the reasons for GPS in cell phones (besides helping the men in black track the locations of "persons of interest") is the problems that have occurred with 911 calls ended up on a tower in a different jurisdiction where the 911 call center wasn't familiar with the place names used by the caller. This often happens on shores of places like Puget Sound and the Bay of Fundy where different jursidictions are separated by bodies of water narrow enough that cell signals can reach towers serving the opposite shore. -- George N.
