Legendarni izumitelj, elektroinžinir, fizik in kemik Nikola Tesla (1856-1943) je že na začetku prejšnjega stoletja napovedal mobilne telefone. V intervjuju za New York Times (spodnja slika), objavljenem v Popular Mechanics leta 1909, pravi:
"It will soon be possible, for instance, for a business man in New York to dictate instructions and have them appear in type in London or elsewhere. He will be able to call from his desk and talk with any telephone subscriber in the world. It will only be necessary to carry an inexpensive instrument no bigger than a watch, which will enable its bearer to hear anywhere on sea or land for distances of thousands of miles."Koncept prvega ročnega mobilnega telefona je delo Martin Cooperja – luč sveta je ugledal 1973, tehtal pa je 2 kilograma.
