Content:  Motorola named Martin Cooper was the first person to make a phone call on April 3, 1973. He decided the first phone call should be to a rival telecommunications company saying "I'm speaking via a mobile phone". However the first commercial mobile phone was released in 1983 by Motorola. In the early 1990s Nokia came into succession, with their Nokia 1011 being the first mass-produced mobile phone. The Nokia Communicator 9000 became the first smartphone as it was inputed with an Intel 24 MHz CPU and had 8 MB of RAM. Smartphone users have increased by a lot over the years

Content:  mobile phone launched on the first US 1G network by Ameritech. It cost $100M to develop, and took over a decade to reach the market. The phone had a talk time of just thirty minutes and took ten hours to charge. Consumer demand was strong despite the battery life, weight, and low talk time, and waiting lists were in the thousands. Many of the iconic early commercial cell phones such as the Motorola DynaTAC Analog AMPS were eventually superseded by Digital AMPS (D-AMPS) in 1990, and AMPS service was shut down by most North American carriers by 2008. In February 1986 Australia launched its Cellular Telephone System by Telecom Australia. Peter Reedman was the first Telecom Customer to be connected on 6 January 1986 along with five other subscribers as test customers prior to the official launch date of 28 February.

Martin Cooper, a former general manager for the systems division at Motorola, led a team that produced the first cellular handset in 1973 and made the first phone call from it. In 1983 Motorola introduced the DynaTAC 8000x, the first commercially available cellular phone small enough to be easily carried. He later introduced the so-called Bag Phone. In 1992, the first smartphone, called IBM Simon, used AMPS. Frank Canova led its design at IBM and it was demonstrated that year at the COMDEX computer-industry trade-show. A refined version of the product was marketed to consumers in 1994 by BellSouth under the name Simon Personal Communicator. The Simon was the first device that can be properly referred to as a "smartphone", even though that term was not yet coined.

The development of metal-oxide-semiconductor (MOS) large-scale integration (LSI) technology, information theory and cellular networking led to the development of affordable mobile communications, and devices such as the car phone. The first handheld cellular mobile phone was demonstrated by John F. Mitchell and Martin Cooper of Motorola in 1973, using a handset weighing 2 kg. The first commercial automated cellular network (1G) analog was launched in Japan by Nippon Telegraph and Telephone in 1979. This was followed in 1981 by the simultaneous launch of the Nordic Mobile Telephone (NMT) system in Denmark, Finland,

Content:  Martin Cooper invented a portable handset in 1973, when he was a project manager at Motorola. It was almost three decades after the idea of cellular communications was introduced by Bell Laboratories. Two decades later, cellular phones made a commercial debut in the mass market in the early 1990s. In the early days of cellular handsets, phone functionality was limited to dialing, and voice input/output. When the second generation of mobile telecoms (so-called 2G) was introduced in Finland by Radiolinja (now Elisa) on the GSM standard (now the world's most common mobile technology with over 2 billion users) in 1991, the digital technology introduced data services. SMS text messaging was the first such service. The first person-to-person SMS text message was

The first handheld mobile phone was demonstrated by John F. Mitchell and Martin Cooper of Motorola in New York City in 1973, using a handset weighing c. 2 kilograms (4.4 lbs). In 1979, Nippon Telegraph and Telephone (NTT) launched the world's first cellular network in Japan. In 1983, the DynaTAC 8000x was the first commercially available handheld mobile phone. From 1983 to 2014, worldwide mobile phone subscriptions grew to over seven billion; enough to provide one for every person on Earth. In the first quarter of 2016, the top smartphone developers worldwide were Samsung, Apple and Huawei; smartphone sales represented 78 percent of total mobile phone sales. For feature phones (slang: "dumbphones"), the top-selling brands were Samsung, Nokia and Alcatel.
