A car phone is a telephone installed in a vehicle that allows the driver or passengers to make and receive calls while on the road. Car phones were popular before the widespread use of mobile phones, offering a way for people to stay connected while traveling. They were usually connected to a car’s electrical system and used a special antenna for signal reception. With the advent of mobile phones, car phones became less common, as portable phones offered greater flexibility. Today, many vehicles come with Bluetooth connectivity, allowing drivers to use their smartphones hands-free.
