After the first commercial cell phone introduced in 1983, which was very popular and the demand was increasing exponentially. This phone also has some disadvantages, for example the cell phone was bulky and expensive with minimal talk time. Many companies then started the research to eliminate the inconveniences and satisfy some customer needs for the pocket cell phone from the portable phone. So in 1986 a company called Technophone created the world's first mobile phone to fit in your pocket and then this phone gave shape to both GSM phones and DTI phones after this creation. Below are the milestones after the introduction of the first commercial cell phone that significantly influenced growth. milestoneThe first milestone I believe is the introduction of 2G technology. This technology has overwhelmed 1G technology in terms of user phone experience, size, cost and much more. The first GSM cell phone, Orbitel 901, was introduced in 1992. During this year, great improvements were made in the field of cell phone technology. He was also the first to receive a commercial SMS. SMS soon became a means of communication among young people. The technology has moved from the first generation to the second generation. Technology also changed during the era when the first cell phone went on sale. When this first cell phone was introduced, it ran on analog technology, but this GSM cell phone ran on digital technology, which was faster and much quieter than its analog precursor. So the popularity of this phone in terms of number of users, call frequency, fewer dropped calls, was much higher than its predecessor. Before the introduction of GSM mobile telephony, the first SIM card was created in 1991 which was the requirement for GSM phones. Furthermore, the advanced and more efficient paper medium...... was increasing for mobile users and the Internet on mobile phones was a big flop in 2008. With the growing Internet population and the massive growth of the mobile population, they have si they have merged together and made the Internet on mobile a compelling experience for users. I conclude by saying that the few main things that pushed people to choose a mobile phone were the operating system, such as Android which is the easiest to use and without forgetting iOS and many others, secondly, capacitive touch screens and the breadth of the screens, as sometimes the user interface is built around the multi-touch screen of the device, including a virtual keyboard, WiFi connectivity and cellular connectivity such as 3G, 4G, etc., phones with higher performance resolution mainly known as "Retina display", camera specifications and, above all, appearance which are often given a higher priority.
