Officially launched in 1991, 2G networks feature only voice calls and text messages, and the technology has lagged far behind the 4G/5G networks that are widely used today. As of September, 142 operators in 56 countries had completed, planned or were in the process of shutting down their 2G/3G networks, according to data released by the Global Mobile Providers Association.
2G/3G has high operating costs and occupies wasteful spectrum resources
With the arrival of 5G, domestic operators encounter 2G, 3G, 4G, 5G “four generations”, but this is not happiness, but pain and pressure, operation and maintenance costs remain high, spectrum resources are limited, site resources are insufficient, seriously affecting the development of China’s information and communication industry.
With the progress of science and technology and the continuous improvement of people’s requirements for communication networks, the communication speed and services provided by 2G and 3G technologies have been unable to meet people’s needs. The spectrum resources occupied by 2G and 3G technologies are also limited, and if we continue to use 2G and 3G technologies, we will waste a lot of spectrum resources.
The situation of 2G and 3G in China: the user base is large, and the pace of withdrawal is slow
The number of 2G users in China is very large. According to data released by the Ministry of Industry and Information Technology, as of 2020, there will be 273 million 2G users on the network, accounting for 17.15% of the total users. Many of these people are elderly people in remote areas, who have less demand for smart phones and mainly make phone calls.
Ling Li, an associate professor at the School of Information Science and Engineering at Fudan University, said that technology iteration is the general trend, and operators are also “breaking away” for 2G/3G networks, but the process is not an overnight success, because there are still many users using 2G or 3G networks. In addition, in addition to phone calls, there is another application can not be ignored, that is, the Internet of Things system used in city management, some of these devices are also using 2G/3G networks to communicate.
Can the mobile phone for elderly continue to be used?
Local operators in Guangzhou China responded that 2G networks would not be available and VoLTE functions would need to be enabled on mobile phones. VoLTE is a call service based on 4G networks, and if you do not have this feature on your phone, you will not be able to continue to use it and will need to buy a new phone. At present, upgrading a 2G mobile SIM card to a 4G or 5G mobile SIM card is free and there is no need to change the plan.
