text: Opponents say that cell phones are good because they give an opportunity to make a call in case of emergency. However, it is an illusion of safety because when people need it the most either they can't find it or reach it because they are stuck in a car. People shouldn't fully depend on cell phones because they are not reliable, and the trusty solution for the difficult situation is OnStar. OnStar is a service that in case of an accident or an emergency will contact you. If you are not able to answer, they will contact the police department, hospital and fire service giving them your exact GPS location. Therefore, nowadays cell phones are unnecessary devices because they are unreliable in emergency situations while On Star is always prepared to help you in an accident.
