What to do with old users after China Unicom 2G network is closed
Four seas network: Recently, China Unicom issued an internal announcement to officially launch the 2G network withdrawal work. 2G network closure is for 5g network business as a foreshadowing. Many 2G network users began to panic, so what about the old users of China Unicom 2G network withdrawal? Let's have a look.
What should old users do after 2G network is shut down?
At present, Unicom suggests that users use 3G or 4G networks.
In 19 years, 2G network was completely shut down. The move is supposed to be a preparation for 5g pre-commercial use. The GSM band is freed up to be used as the communication channel of Nb IOT network. The Nb IOT based on 4G technology is 5g's network deployed for the Internet of things and edge computing in the low-frequency band. According to the style of China Unicom's more and more aggressive promotion of new things and new technologies (mainly supported by Apple watch S3 and ESIM), coupled with China Mobile's recent acquisition of fdd-lte license, it is understandable that China Mobile wants to take the lead in 5g.
For the case of frequency reduction and service withdrawal of 2G base station, the elderly, children's watches and remote areas that have not yet achieved 3G and 4G network coverage will bear the brunt. Without 2G base station signal transmission, such users may not be able to use the basic call function. In addition, the smart phone with dual card and dual standby only supports 2G network, and the secondary card may also become a 'device'.
In the context of 'speed up and cost reduction', the three major operators in China urgently need to reduce the cost of network operation and maintenance, leaving room for the reduction of tariff. In order to solve this problem, it is very important to clear the frequency of 2G and 3G. Although the withdrawal of 2G and 3G will affect the experience of many old users (such as dual card dual standby sub card, 2G old man machine, etc.), it is inevitable for the times to withdraw. 5g era is coming, 2G and 3G network withdrawal is a top priority, we may as well wait and see.
