From the very first mobile phones that were installed in cars to the micro devices that are smaller than the palm of a person's hand, cellular-phone history tracks the technology of radio wave communications. At first mobile phones were installed into cars and only those who had the financial means were able to afford to get them installed. Later, the next-generation models were equipped with a plug that can be inserted into a car's cigarette lighter and were dubbed as "bag phones" and could be transported from vehicle to vehicle.
