The first mobile phone call was made by Martin Cooper on April 3, 1973. It was a Motorola DynaTAC (DYNamic Adaptive Total Area Coverage) prototype. The call lasted for about one minute before it cut off and he had to find a new telephone booth
Martin Cooper made the mobile phone call from the street in New York City to Bell Labs in nearby Holmdel Township, New Jersey. This was just after 4:00 pm EDT on April 3, 1973. The call took place at a time when the world had only 330,000 mobile phones in use.
The device that Mr Cooper used was called a DynaTAC ("Dynamic Adaptive Total Area Coverage"). The device weighed 2.25 pounds (1 kg). It had a flip-up antenna for local calls and
For international calls, it had three-way DTMF touch-tone dialing. Callers would punch in digits 468 for New York, WAL for Washington DC and 555-1212 for Bell Labs (the area code was 302).

The DynaTAC's call is thought to be the world's first using a mobile phone network. It was 50 years ago on March 6 that Bell Labs publicly demonstrated something called the Bell Labs Quad holding four transistorized transistors.
The phone call took place at a time when the world had only 330,000 mobile phones in use. Bell Labs was later acquired by Alcatel-Lucent and is now called Bell Labs Innovations.
In 1973, there were only 130,000 land mobile or mobile telephone subscribers in the United States, according to an article by George Farrar for the Yankee Group published in September of 1997. Incidentally, George Farrar is also the one who coined the term "mobile phone" in a column he wrote for Mobile Technology International magazine back in 1980.
In the same editorial, he wrote that the DynaTAC phone was "probably the world's smallest mobile phone". He noted that it had a very large dynamic range and sounded "like a grating gate being operated with fingernails". He referred to it as the "first actual mobile phone"

The DynaTAC was followed by many other phones. The Motorola DynaTAC-compatible phone appeared on the market in 1975.
George Farrar provides a general timeline of mobile technology. He notes that there were some loopholes in Apple Inc.'s iPhone at it does not have an NID but instead uses an SMS for its 911 emergency calling feature. This allows it to avoid paying the fee, which was up to $0.60 per call just back then.
