What happens when Telecom cdma withdraws from the network?

From a nationwide perspective

my country's CDMA network withdrawals will mainly be withdrawn from remote areas first, then to rural areas, towns, etc., and finally to cities.

Calculate based on the population density, economy, and urban area of ​​each province in our country!

The first wave of large-scale network withdrawals will be in May 2023. By then, the vast majority of rural areas and remote areas in my country may have CDMA signals disappearing first!

The second wave of network withdrawals will probably be in October 2023. Except for the first-tier cities and key areas that temporarily retain CDMA, all other areas in China will be powered off!

In January 2024, CDMA will completely disappear in key areas of first-tier cities and key areas in my country!

In February 2024, China Telecom officially announced that the CDMA base station decommissioning work has been completed!

The technological evolution based on CDMA has been completely suspended, so China Telecom’s CDMA network withdrawal has long been a matter of industry determination. However, in our country, when the existing network still carries users, in order to ensure user communication services Under the prerequisites, withdrawing from the network is not that simple. Therefore, for China Telecom, it must implement step-by-step withdrawal measures, and it must first resettle users of the old network.

What kind of measures is China Telecom currently taking?

First, 5G terminals no longer support CDMA. In China Telecom's latest requirements for 5G terminals, it is particularly emphasized that the 5G terminals launched by mobile phone manufacturers in 2020 must not include CDMA frequency bands. Those that have been on the market before but support them need to have a discontinuation plan.

Second, China Telecom has purchased a number of popular 4G feature phones and will focus on promoting them in the first half of 2020. These mobile phones may be priced at more than 100 yuan and are mainly prepared for low-income and elderly user groups in CDMA. By directly using the 4G VoLTE service on a 4G feature phone, you can clear out 1X voice.

Third, some provinces and cities have officially begun the process of withdrawing from the network. The first thing to be withdrawn is 3G, followed by 1X. As for the specific reason, it is because 3G has become useless and does not have much practical value. Moreover, China Telecom's 4G coverage may be the best among the three major operators. Basically, there is a 4G signal wherever there is 3G. So for ordinary users, what is the point of using a higher 4G network without using 3G? More importantly, in order to free up frequency bands to expand 4G capacity and improve user experience, many 3G frequency bands have been "borrowed", so 3G now exists in name only. Therefore, many netizens have recently reported that the 3G signal cannot be found, but 1X and 4G are normal. Although China Telecom customer service has not given a definite answer, it can basically be inferred that the frequency clearing work has begun in a step-by-step manner.

As for some users asked why they quit 3G instead of 1X? The main reason is that 1X is used for voice calls, and 3G is used for Internet access. Currently, 3G has a better 4G replacement, and 1X needs to be replaced by VoLTE under the 4G network, which requires users to replace their 4G mobile phones. Therefore, 3G first and then 1X is the only way for China Telecom.

In fact, in the author's personal opinion, the conditions for China Telecom's CDMA withdrawal are mature. Moreover, it is now the time for 5G, and it is inevitable to switch to 4G mobile phones. Some users may think that replacing a phone is costly, but China Telecom provides 4G feature phones, and the price is not much different from 2G/3G feature phones, so why not get it all at once!
