Mobile phones were born when the number of mobile users, known as mobileers, made the most popular mobile technology. Mobile phones were originally installed in vehicles permanently, although more sophisticated versions of them, who were called transportable, could also be conducted, which means it could be used as a mobile phone or two way radio. during the forty years, Motorola has developed a two-way radio in a rucksack, the walkie-talkie, which was widely regarded as one of the first phones mobile.

The first mobile phones were called first generation phones, also called 1-g.

The first mobile phones second generation have been commercially launched in 1991 in Finland. While 2G networks were completely digital, networks previous 1-g were analog. One advantage of the 2G networks had over the 1g predecessors was that conversations have been encrypted Digitally phone. It was important because others could fall to the eaves on calls on analog networks. and the present 2G systems were much more effective, allowing more cell phones should be used. Finally, 2g introduced services Mobile data including SMS text messages.

After 2 g mobile phones were launched, the previous systems Mobile telephony has been appointed 1g. while the signs on the analogue radio networks are 1g, and 2G networks are digital, both networks use digital signals to connect the radio towers and the rest of the telephone network.

The first commercial 3G mobile network was launched Japan in May 2001. 3-G was later released on sale in Japan on October 1, 2001.

3G standards for third generation telephony mobile technology, which is the successor to 2G technology. the emergence of 3G technologies enabled network operators such as orange to give users a wide range of more advanced services. This includes wireless Internet access and video calls to high technology.

Despite the success of the 3-g, there are complaints. These include the critical spending 3-G phones, lack of network coverage, because it is still a relatively new service and use high power 3G phones.
