Original title: three major operators are anxious to shut down 2G network! Hundreds of millions of old man-machine users are affected: facing new dilemmas Source: Tencent News
Introduction: since the three major operators continue to speed up the deployment of 5G networks nationwide, while also quietly shutting down 2G networks across the country, according to the information released by the previous three operators, China Mobile Limited will withdraw the 3G network (that is, TD-SCDMA)China UnicomThe choice is to withdraw the 2G network, that is, the GSM network, while China Telecom Corporation withdrew the 2G 3G network at the same time, which means that for many children's watches and old machine users, the future will inevitably be affected, and they will face the embarrassing situation of looking for the Internet everywhere.
According to industry insiders, all three major operators are withdrawing their networks, some 2G networks and some 3G networks, which are also closely related to their 2G, 3G and 4G network layouts. The network deployments of the three major domestic operators are different, such as China Mobile Limited's retired 3G network (that is, TD-SCDMA), but mobile 3G network is the network with the lowest degree of commercialization and the worst user experience among the three major operators. Not only is the network signal coverage poor, but the network speed is also the slowest, so it has been complained by many users. China Mobile Limited's 2G (GSM) network is the most extensive network in the country, with the largest number of GSM users, so China Mobile chose Mobile to withdraw 3 and guarantee 2.
For China Unicom, the reason why he chose to clear 2G (GSM) network is that the signal coverage of Unicom's 2G network is very poor, but the frequency band of Unicom 2G network is very good, and the 900m band of low frequency is more suitable for the basic coverage of 4G and 5G network. So China Unicom chose to clear the 2G network and free up the original low frequency for the construction of 4G and 5G networks. more importantly, China Unicom's 3G network can carry voice calls without having to drop back to 2G networks or use 4GVolte to complete voice calls.
At the same time, China Telecom Corporation chose to withdraw the 2G/3G network, because the telecom 2G/3G network originally belonged to the same network, especially in rural areas. At present, the telecom 2G network still needs to carry 2G voice call function, because the current telecom Volte does not have the ability to replace 2G network calls, so according to industry insiders' estimates, China Telecom Corporation will not completely withdraw the 2G/3G network until around 2025. But just recently, netizens exposed China Telecom Corporation's official customer reply: as most cities have shut down 2G networks, there will be no signal and voice call service after shutting down. So you need to replace your phone watch, 2G old machine and other equipment. China Telecom Corporation began to shut down the 2G network as early as 2019 to avoid unnecessary waste of resources. "
However, many netizens also applauded the fact that "operators shut down 2G and 3G networks": "because after the three major operators have withdrawn their 2G and 3G networks, we can further get rid of our dependence on Qualcomm Inc. Avoid paying high 2G and 3G patent fees." However, there are also many old man-machine users and children's watch users have expressed their dissatisfaction, because 2G network-style mobile phones and phone watches have to say goodbye thoroughly.
Finally: dear friends, what do you think about China Unicom retiring 2G network, China Mobile Limited retiring 3G network, and China Telecom Corporation retiring 2G/3G network at the same time?
