The first phone call made from a mobile device took place back in 1973, when Dr. Martin Cooper, inventor of the Motorola DynaTAC 8000X tested his prototype in the streets of New York. Ten years later, in 1983, the first ever mobile phone was available to everybody. The weight and size of the phone (0.8 kilograms and 25.4 centimeters) made it close to impossible to carry the phone around, so it was mainly used in cars.
