When was the first cell phone call made?
The first handheld mobile phone call happened in 1973 using a device that weighed as much as a brick.
Motorola engineer Martin Cooper made the call while walking on a sidewalk in New York City. He used a prototype phone to call a rival scientist at another company. This proved that people could talk to each other from anywhere without being tied to a house or a car.

On April 3, 1973, Martin Cooper called Joel Engel of Bell Labs to show off the new technology. The prototype phone weighed 2.5 pounds and was 9 inches long. It was so heavy and bulky that people nicknamed it the brick.The battery only lasted for 30 minutes of talking. It then took 10 hours to charge the battery back up. The system worked by using a cellular network. This network divides a city into small areas called cells.Each cell has its own low-power transmitter to send signals. This design allows many people to use their phones at the same time without the signals getting mixed up. Before this invention, mobile phones were usually bolted into cars because they needed large batteries.The first version sold to the public was the Motorola DynaTAC 8000X in 1984. It cost nearly $4,000 which is over $11,000 in today's money. Cooper was inspired by the handheld communicators used in the science fiction show Star Trek.
