1. Do I need to change my mobile phone?
No matter which company's 3G service [2] is adopted, it is necessary to switch to 3G mobile phones. At present, there is no large-scale listing of 3G mobile phones in China, but 3G mobile phones developed by various mobile phone manufacturers will be launched one after another this year.
On the premise of using 3G mobile phones, mobile and telecom users can upgrade to 3G without changing their mobile phone numbers. Among them, Mobile has introduced the "three noes" policy, that is, all China mobile users do not need to change their mobile phone numbers and SIM cards, and do not need to register in the business hall, just insert the original SIM card into 3G mobile phones.
According to media reports, China Telecom also plans to launch a similar "three noes". In addition, according to the scheme disclosed by China Telecom, all users including China Telecom133153 can use the current 189 "Tianyi" service before the end of March.
China Unicom said that WCDMA will be launched in May, and users of Unicom 130,13, 132 and 156 can directly upgrade 3G without changing their numbers.
2. Will it be expensive?
Lu Xiangdong, vice president of China Mobile, said on 14 that it would be cheaper to use 3G than to use 2G, and China Mobile would give preferential treatment to 3G users on the basis of unified pricing. Users will enjoy certain discounts on all services on 3G networks, including voice and Internet access.
108, 65438 The relevant person in charge of China Mobile Marketing Department also said that 3G tariffs will be used together with all packages of existing 2G networks, and the tariff structures and standards of 3G and 2G will be unified and priced uniformly. At present, the new tariff package has been launched in eight cities and regions such as Beijing and Shanghai, and will be promoted nationwide after network transformation.
The standard tariff of China Telecom in Beijing area 189 is 50 yuan per month, and local calls to 0.4 yuan are free per minute. Call 0.6 yuan/min when roaming in different places, and answer 0.4 yuan/min. In addition, paragraph 189 also launched a business trip package and a chat package. The mobile internet traffic fee that exceeds the package is only 0.005 yuan per 1KB. This price is nearly 50% lower than before.
Liu, director of the Science and Technology Committee of China Unicom, believes that the tariff level in the 3G era will not exceed that in the 2G era. He said that in the era of 1G and 2G, due to the lack of technology patents in China, foreign enterprises earned more than 750 billion yuan from China. In the 3G era, TD-SCDMA with independent intellectual property rights in China can not only save a lot of patent fees, but also contain the prices of other standard products.
In fact, consumers have actually felt the price reduction benefits brought by 3G. For example, China Mobile reduced its tariffs by 30% nationwide at the end of last year, among which the mobile phone data traffic fee was the biggest drop. Starting today, the three major operators, China Mobile, China Unicom and China Telecom, have also officially cancelled the differential pricing between SMS networks, and uniformly charged each SMS at 0. 1 yuan. I believe that with the popularity of 3G, consumers will enjoy more and more benefits.
3. When can I enjoy 3G service?
China Mobile said that at present, only users in Beijing, Shanghai, Tianjin, Shenyang, Qinhuangdao, Guangzhou, Shenzhen, Xiamen and other cities 10 can apply for TD services. In June this year, TD network will cover all provincial capitals and cities with separate plans. According to the plan, by 20 1 1, TD network will cover all cities in China.
China Telecom and China Unicom also released the 3G service schedule today. Zhang Jiping, executive vice president of China Telecom, said yesterday that 3G services will be provided in 65,438+000 major cities by the end of March, and 3G services will be launched nationwide in July this year.
Chang, chairman of China Unicom, said in Hongkong yesterday that he planned to launch 3G services in 55 cities in China in the first half of this year, and planned to expand the coverage of this service to 282 cities by the end of this year. At the same time, it predicts the profit of 3G services in 20 10 years.
4. Is it compatible with 2G?
Cao Shumin, vice president of the Institute of Telecommunications Research of the Ministry of Industry and Information Technology, recently attended the "2009 China Communication Technology Annual Conference", and said that although 3G licenses have been issued, due to the obvious dual structure in China, 2G will remain the focus of operators for some time to come, and the future will be a market structure in which existing 2G networks and 3G*** will jointly develop. The three major telecom operators also made it clear that 3G network construction will be integrated with 2G network. Whether existing mobile phone users use 3G services depends entirely on their wishes.
In addition, Professor Zeng from the School of Economics and Management of Beijing University of Posts and Telecommunications believes that 3G will not affect the normal use of 2G users. He said that 3G to 2G has downward technical compatibility, and it is no problem for 2G to call 3G or connect 3G from 2G, just like DVD backwards compatibility, which can accommodate VCD. Therefore, 3G access will not affect the phone calls and short messages of 2G customers, and will not increase the charges, especially for the networks from 2G to 3G.
5. Can it be interconnected across the network?
Professor Zeng said in an interview with China Economic Net a few days ago that there is no essential difference between TD, WCDMA and CDMA2000, and they are all based on CDMA or CDMA. It was first invented by Americans, and the European Union thought it was wideband CDMA, so it was called WCDMA. In fact, European standards also originated in the United States. TD-SCDMA independently developed by China is the abbreviation of Time Division Multiple Access (TDMA) technology. It is a new standard that combines the advantages of TDMA and CDMA. In terms of standards, China's technology is more advanced.
He thinks each of the three cards has its own advantages. The regulatory authorities have been actively supporting TD-SCDMA licenses with independent intellectual property rights, but at present, their maturity is not very good, mainly because they are not as good as WCDMA and CDMA2000 in the market, because WCDMA and CDMA2000 have been commercialized in some countries. Therefore, it may not be as good as the other two standards in a short time, but in the long run, it will definitely be at least equal to the other two standards.
WCDMA is the most mature 3G technology at present. Unicom's extensive 2G customer resources can realize the transition from 2G to 3G, and WCDMA technology has the most perfect industrial chain among 3G technologies at present.
Because both TD-SCDMA and WCDMA need to rebuild their networks, and CDMA networks can provide 3G services through direct upgrade, China Telecom has a slight advantage in 3G network coverage.
At present, it is not only China that adopts various 3G technical standards at the same time. South Korea uses WCDMA and CDMA2000 standards at the same time for TD-SCDMA commercial trial. Zeng Qiujian said that the three technical standards can be interconnected in China, but whether they can be interconnected with foreign countries needs to confirm whether the other party accepts the standards, which requires consumers to pay more attention.
