Tencent's "One Line" Guo Xiaofeng reported on April 12

In response to the argument that China Unicom has shut down its 2G network, Tencent’s “First Line” has been confirmed by China Unicom’s official confirmation for the first time. This also means that the 2G network that has served 10 years will be withdrawn from the stage of history.

China Unicom stated in its response that from the perspective of providing users with better quality and faster networks, the provinces are deployed to carry out 2G user replacement operations and base station frequency reduction work.

In addition, for 2G frequency-reduction areas, users do not have to worry about their original 2G mobile phone cards can not continue to use, China Unicom will exchange mobile phone cards for free, give experience flow, discount purchases and other promotional activities to help 2G users to 3G, 4G migration allows users to experience more affordable and smooth communication network services.

Subsequently, Tencent “First Line” was informed by some provincial companies of Unicom that the current 2G retreat network has been carried out in some branches, and the first-tier cities such as Beishangguang have not been notified and will eventually be implemented according to the requirements of the Group.

From the point of view of industry trends, stopping the 2G network is also a general trend.

Previously, from 2009 to 2012, Japan’s NTT-DoCoMo, KDDI, Finnish operators, and Telecom New Zealand, South Korea’s KT have announced the suspension of 2G services.

On the one hand, with the transition of 2G users to 3G/4G networks, the services provided by 2G networks are gradually decreasing, but the maintenance costs have not been reduced. Operators now need to maintain 2G, 3G, 4G three networks, and 5G networks in the future, which will undoubtedly greatly increase costs.

On the other hand, shutting down the 2G network will shift the spectrum resources to 4G/5G, and it will be able to obtain a technological innovation dividend and be conducive to industrial development. U.S. telecommunications operator T-Mobile also started a similar plan in early 2014, closing some 2G networks and deploying 4G LTE networks in more areas. For Chinese operators

Regarding whether shutting down the 2G network will affect the call, everyone does not have to worry about it.

It is understood that taking the current 4G network as an example, many performance indicators of 4G are 100 times more than those of 2G. As far as voice is concerned, in a typical configuration, the capacity of a single-station concurrent user, GSM, is only 42, while 4G is as high as 1200, which is a 28-fold increase. The VoLTE high-definition voice service quality is much better than GSM.

However, users in some remote locations may have some impact. Because there is no 2G network, 3G and 4G signals can't get up and the phone can't hit.

According to unofficial data, China Unicom currently has about 2% of total 2G subscribers. According to 2017 China Unicom's 280 million mobile subscribers, the number of 2G subscribers is about 5 million. Therefore, for China Unicom, it is necessary to do a clean-up plan to avoid these problems.

According to another data, there are still 1.57 million 2G base stations, 290 million 2G users, and massive IoT devices that are more dependent on 2G networks at the end of 2017. 2G network exit is not a one-stop task, and some are quite difficult and complicated. Operators to solve.

The other two operators, China Mobile did not comment on the shut-down of 2G networks, and China Telecom stated to Tencent “First Line” that it would not be shut down for the time being.
