What benefits will 3G bring in the future?

Nanfang Daily summarized all kinds of consultation questions of consumers in the TD Experience Hall and many channels, as well as some experiences of personally participating in the actual experience. On the basis of the "3G Experience Report" for the first time last week, Nanfang Daily once again launched "3G Nine Questions", looking forward to playing 3G and TD with you!

What benefits can 3G mobile phones bring?

High-speed Internet access is one of the biggest selling points of 3G. At present, the theoretical speed of TD can reach 384 K /S, and it is estimated that the theoretical download speed can reach 2.8 megabits /S at the end of the year with the enhancement of 3G HSDPA, which is much faster than the current ADSL network speed. After the speed is improved, all kinds of network applications are like a duck to water, and browsing the web, sending and receiving emails and downloading music and movies can be easily done. Distance education and telemedicine are considered to be very promising industries. After the deployment of 3G, the acceptance of education and medical care is no longer limited by space, and it is believed that it can develop rapidly.

For example, some high-end monitoring equipment can be connected to the server of the medical center in real time through 3G, so that patients or nursing recipients can get treatment or care in real time anywhere. There are also video calls, mobile TV and so on, all of which are new experiences that 3G mobile phones can bring you.

Can TD roam abroad?

The author saw this scene in the mobile TD experience hall on the first day of numbering: a middle-aged man rushed into the TD experience hall and said to the staff, "I want to buy a TD mobile phone and go to Korea for business next week." The other party replied, "TD can only be used in 8 cities in China at present, and it is impossible to roam internationally." The man complained, "Isn't TD a 3G mobile phone? I can't use it when I go abroad, and I dare to play 3G mobile phones. "

Here, it is necessary to elaborate on several standards: the second generation mobile communication (2G) has two international standards: GSM, China Mobile and China Unicom; China Unicom uses CDMA. There are four international standards for the third generation mobile communication (3G): WCDMA is an upgraded version of GSM in the 2G era, which is mainly used in Europe at present; CDMA2000 is a 3G upgraded version of CDMA, which is currently mainly used in North America and other places. TD-SCDMA is a 3G standard independently developed by China. At present, it is only tried in 8 cities and a few countries in China, and it is impossible to provide roaming service abroad. The last standard is WiMax, so I won't talk about it here.

Can the 3G mobile phone brought back from overseas be used in the mainland?

Because China Mobile's 3G network uses TD-SCDMA, a standard independently developed by China, and 3G mobile phones in Hong Kong or abroad generally use WCDMA and CDMA2000, 3G mobile phones brought back from Hong Kong or abroad are hardly used in mainland China, but it is not excluded that a few mobile phones have this function.

Don't be too sorry if you have bought a 3G mobile phone that doesn't support TD standard abroad. Although WCDMA and CDMA2000 networks have not yet been built in China, it is believed that with the reorganization of telecommunications and the issuance of 3G licenses, the other two 3G networks will also be rolled out.

Do TD mobile phones exist outside 8 cities?

At present, China Mobile has opened eight cities including Beijing, Shanghai, Tianjin, Shenyang, Qinhuangdao, Guangzhou, Shenzhen and Xiamen as pre-commercial areas, which means that only these eight cities have TD networks. If you leave these eight cities, will TD mobile phones become "scrap iron"? The answer is no.

As the six terminals released by China Mobile in the first batch all support dual-mode functions, they can smoothly switch between the existing GSM network and TD network, and TD mobile phones will automatically switch to local GSM networks outside the eight pilot cities, which can be used as usual, but the special functions of 3G cannot be realized.

For example, you bought a TD mobile phone in Guangzhou with a special U-SIM card. If you leave Guangzhou for Zhuhai, your TD mobile phone can still use the local GSM network without the local T network, and the functions such as calling and texting can be realized. It is worth noting that replacing the U-SIM card in TD mobile phone with the original GSM network SIM card is self-defeating, because TD mobile phone only supports its exclusive U-SIM card, and other cards will display the words "SIM card is not supported", so it cannot be used.

Can TD mobile phones watch mobile TV?

Earlier, some media said that at present, TD mobile phones have turned off mobile TV and streaming media services, so they can't watch them, which is a misinformation. TD is the product of 3G era, and mobile TV and streaming media applications are just one of its "killer" applications. If this function cannot be realized, TD can hardly be called a 3G mobile phone.

In fact, there are many ways to watch mobile TV. Here is a recommendation. Enter Monternet's home page, turn on the mobile TV item, and you will be prompted to download and install the mobile TV player software. After the installation is completed, you can directly enter the mobile TV from the startup icon of the software, and you can watch your favorite TV programs according to the directory. Because there are not many program sources that China Mobile can provide at present, you can also watch more TV programs by downloading streaming media software such as GGLive or logging in some WAP portals.

Can TD card be used on GSM mobile phone?

The full name of TD card is U-SIM card, and China Mobile named it Pioneer Card. Compared with the SIM card of GSM network, both of them are the same in size, shape, size and chip shape, and the only slight difference is that two tiny notches are opened at one end of the U-SIM card. Although these two cards are similar in appearance, they cannot be replaced with each other.

Some consumers have played such a "small abacus": to buy a TD card, you only need a 20 yuan, and you can use it by plugging it into your current mobile phone, so that you can have the first batch of valuable TD "reputations" and you don't have to spend money on TD mobile phones. Unfortunately, this road is not feasible. If you want to experience TD network as early as possible, you can only buy a TD mobile phone and a special U-SIM card.
