I want to buy a 3G mobile phone that supports TD SCDMA, please give a comprehensive answer to the ma

TD is only operated in our country, so there is no parallel import!

Licensed goods can consider Samsung i688, TD smart phones.

Samsung Dopod S700, TD smartphone.

It is best to buy licensed goods in licensed goods and parallel goods, because the quality of licensed goods is relatively good, and parallel goods are basically infringement.

At present, there are only a few domestic mobile phones in China that support TD-SCDMA, such as Huawei, ZTE, Lenovo, and only in Beijing, Shanghai, and other 10 cities that have opened 3G

Junk Network - It's better to buy a wcdma and wait. The Internet speed is the same as that of today's CDMA mobile phones. Also 3g....

No matter how good it is said on the market, it does not meet the requirements and standards of the 3G network, and it is troublesome to buy, only the mobile customized one is **, what model depends on the province where you are located!

TD-SCDMA, now China Mobile is also an independent scientific research brand vigorously supported by the state, the service must not be said, 3G speed is about the same, mobile official website TD12580** Press me to help you take a look.

Let's use WCDMA! It is the universal 3G network in the world. You go and see the 3GS5628 Ferris wheel.

Yes, it is a dual-mode mobile phone, but it can only use China Unicom's G network signal (that is, WCDMA) or mobile G network and mobile TD network signal, and China Telecom's CDMA (3G) so your mobile number cannot be used.

I am a communications professional, you know the meaning of generation in English, that's good - I tell you that 3G means the third generation of communication transmission signal standards, that's it, in fact, 3G technology has matured many years ago, the market at that time could not afford 3G consumption, so at that time SMS was more favored by mainland consumers, now with the reduction of costs, and the maturity of the market, the third generation of communication systems, has been put into a wide range of promotion.

3G is the third generation of mobile communication technology, which refers to cellular mobile communication technology that supports high-speed data transmission. 3G services can transmit both voice and data information at the same time. 3G is a generation of mobile communication system that combines wireless communication with multi-level communication such as the Internet.

3G network technology, compared with the first generation of mobile communication technology (i.e., 1G) and the second generation of digital mobile phone communication technology (i.e., 2G), 3G mobile phones mainly combine wireless communication and international Internet and other communication technologies to form a new mobile communication system. This mobile technology can process images, forms such as meetings, and in addition to this, it also includes some business functions such as meetings. In order to support the above functions, the wireless network can fully support different data transmission speeds, i.e., whether it is outdoors, indoors or in a driving environment, it can provide data transmission speeds of at least 2Mbps, 384kbps and 144kbps.

First of all, the network standard is determined by the hardware, and then see whether it is a dual-mode mobile phone Yes, a dual-mode mobile phone can support 3G and 2G switching between each other, but a single-mode 3G mobile phone cannot.

It means that it supports 2G and TD (communication mode, this is fixed) type of 3G network, and 2G network can be used with China Unicom card;

You can use China Unicom's 2G network. China Unicom 3G is not supported. This is a mobile 3G phone.

TD-SCDMA: Code Division Multiple Access Technology for Time Division Synchronization 3G: The third generation of mobile communication technology.

TD is the first international standard in China with independent intellectual property rights, creating a precedent for China to participate in international telecommunication standardization. TD is one of the mainstream 3G standards in the world. The TD standard is a model of technological innovation in China's communications industry and an important contribution to the development of the third generation of mobile communications.

TD-SCDMA (Time Division-Synchronization Code Division Multiple Access) means Time Division Synchronization Code Division Multiple Access in Chinese.
