What is the so-called C network G network? Which is better?

The temporary situation is that the user development of China Unicom's C network is not as good as that of China Mobile's G network, or even worse than that of China Unicom itself. There are mainly the following factors.

First of all, I personally think that China Unicom made a mistake in its marketing strategy at the initial stage of CDMA network construction. When China Unicom started to build CDMA network, it spent tens of millions of dollars to ask McKinsey to do marketing strategy for them. The answer given by Mackenzie is to rely on the technical advantages of CDMA over GSM to develop high-end users and strive for high-end users of China Mobile. This decision now seems completely wrong. First of all, CDMA has obvious advantages over GSM in technology, especially for high-speed packet data services. However, in the initial stage of CDMA network construction, the coverage of the network is far less than that of the mobile G network that has been built for many years. High-end users have strong roaming, how to use C network? Moreover, the Ministry of Information Industry has not approved the domestic open number portability function, which means that users have to change their numbers when changing networks. And this is also a taboo for high-end users. So the result is that China Unicom's C network has poached its own G network users, and there are not many users, which basically does not pose a threat to mobile.

Secondly, the mobile phone terminal is also a problem. Considering the usage habits of domestic users, China Unicom decided to adopt a mobile phone with separate phone and card. It is hard to say that this judgment is wrong, but it has proved to be a great obstacle to the development of C network users. Because of all the operators' C networks in the world, only China Unicom has used mobile phones with separated cards on a large scale. Therefore, mobile phone manufacturers must customize mobile phones for Unicom on a small scale. Small quantities will lead to high prices. As a general mobile phone user, I don't really care about G network or C network, but I especially care about the price of mobile phones. With the same grade of mobile phones, the price of C network is much higher than that of G network. It was not until China Unicom decided to adopt a mobile phone subsidy policy for users of C network that this problem was solved. But another result is that the high subsidy cost makes the actual profitability of China Unicom's C network very poor.

Now from a technical point of view, Unicom's C network is at least equal to the mobile G network, and many places are better than the mobile G network. But in layman's terms, the brand has been screwed up and it is difficult to get it back.
