During the transition from 4G to 5G, do I need to change my mobile phone or SIM card to use the 5G network?
Global 5G standard patent statement
China enterprises account for more than 30%.
The 5G standard is a unified international standard jointly formulated by the global industry. By the end of 2065438+May 2009, China enterprises accounted for more than 30% of the 5G standard essential patent statements among more than 20 enterprises in the world, ranking first.
Gong Daning, Senior Engineer, Institute of Policy and Economics, China Institute of Information and Communication Technology: In terms of industrial development, China took the lead in launching the R&D experiment of 5G technology, which accelerated the R&D and industrialization of 5G equipment. At present, China's 5G IF system equipment, terminal chips and smart phones are in the first echelon of the global industry.
At present, the application of domestic 5G pilot cities has been widely spread. In Guangzhou, the ultra-high definition industry formed by 5G+4K has also become a new growth point for Guangzhou to stimulate the economy.
Hu Zhigang, Chief Engineer of Guangzhou Bureau of Industry and Information Technology, Guangdong Province: This year, Guangzhou plans to build more than 1 10,000 5G base stations to achieve full coverage of 5G signals in the main city and introduce more than 1000 leading enterprises in big data and artificial intelligence information consumption. By creating more new information consumption scenes and products, people will have more information consumption experience and sense of gain.
In Shanghai, up to now, more than 20,000 communities have opened gigabit fixed broadband based on optical fiber, covering tens of millions of users.
Liu Yuefeng, Director of the 5G Special Promotion Office of China Telecom Shanghai Company: At present, we have completed the planning of 20,000 5G stations in Shanghai, and plan to start the construction of 3,000 stations in advance in 20 19.

The Ministry of Industry and Information Technology said that in the research and promotion of 5G, China has always adhered to the concept of openness, tolerance, cooperation and win-win situation. In the technical trial stage, many foreign companies, such as Nokia, Ericsson, Qualcomm and Intel, have been deeply involved. With the joint efforts of all parties, China 5G has a commercial foundation.
5G commercialization is coming soon.
Change your mobile phone or SIM card?
As users, we are most concerned about whether we need to change our mobile phone or SIM card if we want to use the 5G network during the transition from 4G to 5G.
If users need to enjoy the convenience brought by the 5G era, they must change their mobile phones.
Compared with the original 4G era, 5G needs to use higher technology and frequency, but the current 4G mobile phones can't meet the demand of this technology, and 4G mobile phones can't support 5G through upgrading.
The good news is that unlike the transition from 3G to 4G, users need to change their cards. According to the news released by the three major operators, users can experience 5G high-speed Internet access and voice services without changing cards or numbers, thus avoiding the trouble of frequent card changes.
For some people, "does the advent of the 5G era mean that my 4G mobile phone will be eliminated?" Doubt, the answer is no.
Before the arrival of the 4G era, there were still a large number of 2G users using mobile services normally. Therefore, users who are not in a hurry to experience the 5G network can continue to use the current 4G mobile phones, and operators can still provide good 4G network support.
