The third generation of network smart phones is the perfect combination of 3G handsets and smartphones. The so-called "3G mobile phone" Chinese full name for the third generation (the 3 Generation) phone.

With the development of science and technology and economy, mobile phone variety and model is also more people dizzying, from the first generation of analog mobile phone to the second generation of GSM, FDMA and other digital mobile phones, to the third generation of WCDMA mobile phone, mobile phone has become A new generation of mobile communication systems that combines voice communications and multimedia communications and includes value-added services such as images, music, web browsing, teleconferencing, and other information services.

What is the difference between a 3G phone and a smartphone?

The two can not be compared with each other, because the intelligence refers to the software can be used more, 3g refers to the link.

3G mobile phone refers to: support third-generation mobile communication system standard mobile phone, both 3g mobile phone, and domestic operation of the 3g standard includes cdma2000 (China Telecom Tianyi 189), wcdma (China Unicom wcdma), td-scdma (China Mobile td-scdma), as long as the phone supports the above three kinds of standard in one of the words, that is, 3g phone.

Smart phone, refers to the same as the personal computer, with a separate operating system, independent operating space, users can install their own software, games, navigation and other third-party service providers to provide the program, and through mobile communication network to achieve wireless network The general name of the access phone type.
