This is a reenactment in A hand-held mobile radiotelephone is an old dream of radio engineering. In , Finnish inventor Eric Tigerstedt filed a patent for what he described as a "pocket-size folding telephone with a very thin carbon microphone". Among other early descriptions is one found in the science fiction novel Space Cadet by Robert Heinlein.
The protagonist, who has just traveled to Colorado from his home in Iowa, receives a call from his father on a telephone in his pocket. Before leaving for earth orbit, he decides to ship the telephone home "since it was limited by its short range to the neighborhood of an earth-side [i. Clarke envisioned a "personal transceiver, so small and compact that every man carries one.
First commercially available, hand-held cellular mobile phone, Early predecessors of cellular phones included analog radio communications from ships and trains. The race to create truly portable telephone devices began after World War II, with developments taking place in many countries.
These "0G" systems were not cellular, supported few simultaneous calls, and were very expensive. The first handheld mobile cell phone was demonstrated by Motorola in The first commercial automated cellular network was launched in Japan by Nippon Telegraph and Telephone in These first generation "1G" systems could support far more simultaneous calls, but still used analog technology. In , the second generation 2G digital cellular technology was launched in Finland by Radiolinja on the GSM standard.
This sparked competition in the sector as the new operators challenged the incumbent 1G network operators. By , it had become clear that, at some point, 3G networks would be overwhelmed by the growth of bandwidth-intensive applications like streaming media. Features Main article: Mobile phone features See also: Smartphone All mobile phones have a number of features in common, but manufacturers also seek product differentiation by adding functions to make them more attractive to consumers.
This has led to great innovation in mobile phone development over the past 20 years. The common components found on all phones are: A battery, providing the power source for the phone functions.

The SIM card allows users to change phones by simply removing the SIM card from one mobile phone and inserting it into another mobile phone or broadband telephony device, provided that this is not prevented by a SIM lock.
From onwards they became popular in India and Indonesia and other emerging markets,  attributed to the desire to obtain the lowest on-net calling rate. In Q3 , Nokia shipped 18 million of its low cost dual SIM phone range in an attempt to make up lost ground in the higher end smartphone market.
