What is the impact of changing the network and not changing the number?

The number remains the same, but the operator has changed, and nothing else has affected it.

The port number transfer brings a zero-sum game, but it does not bring a substantial increase in users. This is a trade-off relationship. In terms of value, there is no doubt that most portability leads to the loss of industry value, and the user value will basically not increase. This is just a battle for the number of users, not a real service war, because the homogenization and over-marketing of products and services in the industry have become very serious.
