How to cancel the caller ID of Shenzhouxing? Does it take effect immediately after cancellation?

Call 10086 for cancellation, or bring my certificate to the business hall for cancellation. Before canceling, ask if your caller ID is charged. If it is free, there is no need to cancel it. In theory, cancellation will go through a certain process and take several hours to take effect. You have to consult the local 10086 for the specific time. But in practice, it takes effect immediately in most cases.
