i think its definately worth it, when i had my accident, my truck was upside down, and i had no one to help me for about 20 minutes when i finally got out, after that i was wandering around like a 70 year old drunk man trying to find a phone to let my parents know what was going on.

so i guess after reading what i just said. someone else is almost always going to be at an accident to call the police, and youll either always have your own phone or you can bleed all over someone elses like i did to call your parents or sig other ha

im not sure on the price for it but if its not a ton, i say why not, its for your safety, and if it is a lot then just drive with a cell phone, they can track the accident through that if you cant tell where you are.
