Exactly 37 years ago, on September 21, 1983, the Motorola phone was certified by the US Federal Communications Commission and officially became the world’s first mobile phone.

The device was called the Motorola DynaTAC 8000X and weighed 800 grams. It was a tube measuring 22.5 × 12.5 × 3.75 cm without the antenna.

Yes, the model went on sale in 1984. Consumers were so impressed that they were able to stay connected that thousands of people signed up to buy the DynaTAC 8000X, despite the high cost of the novelty – the price of the device was 3 thousand 995 dollars.

The DynaTAC 8000X battery allowed you to communicate for 35 minutes, but it took more than 10 hours to charge.

The LED display of the first mobile phone was red and could only show the number to call. The keypad consisted of 12 keys (10 numeric buttons and two for making and ending a call), as well as 9 special keys: Rcl (Recall – redial), Clr (Clear – reset), Snd (Send – send), Sto – key “remember”, Fcn (Function – functions), End (End – end), Pwr (Power – power on), Lock (Lock – lock), Vol (Volume – volume).

It was this phone that was picked up by its inventor, Motorola employee Martin Cooper, on April 3, 1973, and made the first call to AT&T competitor Joel Engel.

After concluding the conversation and holding a press conference, engineers and developers realized that they had made a great revolution in the world of communications.

It was a real triumph. At that time, we used 14-kilogram phones in cars. Their ability to fit everything you need in 1 kg was a big breakthrough“- recalled years later, the head of systems development AT & T Bell Laboratories Richard Frenkel.
