The three major operators have all started to quit the network for 2G and 3G.
Now many friends are probably used to the 4G network, but there are about 400 million 2/3G users in China, mainly in remote and western areas. The supporting facilities in these areas are not perfect, so we can only transition through 2/3G networks first, and then fully start 4G when the time is ripe.
In terms of network withdrawal, China Mobile will give priority to gradually withdrawing from the network in 3G, while China Unicom and China Telecom will withdraw from the network at the same time in 2/3G.
What are the reasons for quitting the network?
The main reason for quitting the network is that the facilities of 2/3G base stations are backward and occupy spectrum. It's really time to replace these.
Everyone can understand that with the development of technology, the old base station can no longer support the use of the current 4G network and needs to be updated. 2/3G networks still occupy 4/5G spectrum. If these old networks are gradually slimmed down, more spectrum can be freed to deploy 4G, leaving enough space for the future 5G, then the withdrawal from the network is certain and will gradually accelerate in the future.
And now that 5G has been fully deployed, it is logical for 2G and 3G to quit.
Logging out of the network will not affect the use and call temporarily.
Although it's time to quit the network now, there must be a time process, which will gradually quit the network without affecting the user's use, and it will definitely not affect the user's use in the near future.
At present, the three major operators give priority to 3G's withdrawal from the network, and it is very likely that 2G will not withdraw from the network eventually because it involves telephone business. But in the 5G era, the network speed will definitely get faster and faster; Although a 5G mobile phone is more expensive, it is still possible to switch to a 4G mobile phone.
