Mobile phones have been a long way since the early 1980s when they were brick-sized and almost weighed. Today, mobile phones are equipped with built-in cameras, polyphonic ringtones and high-tech games. The new "3G" mobile phones can also download full movie capture and full spectrum music. Since there were only a few mobile phone manufacturers in the 1980's, there are many today. In addition to the original manufacturers such as Motorola and Siemens, today the phones are manufactured by Sony-Ericsson, LG, Toshiba, Samsung, Hitachi, Danger, Palm, HP and others
the old CDMA and TDMA standards are replaced by GSM, a global standard outside North America. The relatively new mobile phone companies, such as Vodafone and T-Mobile in Germany and NTT DoCoMo in Japan, are expanding their mobile phone offering and plans worldwide. Traditional computer companies are either moving or moving to the mobile phone industry – PalmOne is producing Treo 650, HP's own smartphone PDA comes out and Microsoft also offers many new mobile phone operating systems  Wireless voice communications As one of the ways mobile phones have become mobile computing platforms over the past decade. These new mobile phones are so powerful that they load many applications that had to be placed on a desktop computer a few years ago.
In parallel with technological innovation and increasing acceptance, hardware and service plans have been steadily declining in the past decade. While only a few years ago, most mobile phone providers need 3-year contracts with serious penalties for early resignation, we now only have a one-year contract to get a freely available mobile phone.
In addition to mobile phones, hardware and all new industries meet mobile phone users who require accessories such as mobile phone covers, screen savers, and ringtones. SMS (Simple Messaging System) and MMS (Multimedia Messaging System) language are also slowly entering the cellular society. Abbreviated abbreviations (such as LOL (laughing loudly), SWAK (kissed), and G2G (transmission) give secondary character to TVs who are the main users of the telephone message worldwide.
