This emergency dual-band GSM cell phone has something that until now you & your current phone could only dream of: A 15-year battery life. It is made for emergencies and automatically transmits its location. At $50 this is a small pricetag for some serious piece of mind. Throw one in the glove box and when you’re stranded on the side of the road with a dead car and dead iPhone, you’ll be glad you did.
