Any cell phone I've ever heard of can always call 911 even if it's not
paid, registered or whatever. If you keep it in the car, better have a
charger that plugs into the cig lighter. Actually my brother just told
me there is a cheap low wattage $10 inverter so you can use the free
120VAC charger in the car and never buy another special car charger again.

That's an odd way to save the $3-5 cost of a car charger.
