The first wireless call happened in 1973 thanks to Martin
Cooper, an engineer at the telecommunications company
Motorola. In the years that followed, technological advances
allowed the development of the first mobile phone models that
made it possible to communicate from anywhere. At this point,
the call could have a maximum duration of 30 minutes.

From there, by the 1990s, there were already countless brands
selling cell phones. Some were more compact and even had a
cover to protect them from bumps. The next great addition to
mobile devices was the color screen. But it was not until this
century that the first phone appeared with a built-in camera that
made it possible to take photos. Then came text messages and
multimedia messages (which could contain images and sound). In
2007, up to 1.9 trillion messages were recorded worldwide.
