How does Unicom close a business in two cities?

Different provinces have different ways to close a family in two cities. For example, users in Henan have opened discounts for two cities in Luoyang, and they can send a text message to 100 10 to cancel. This service is called Shuangchengtong in Hubei. If you want to cancel sending QXLCT or canceling the communication between the two cities to 100 10, cancel. For the specific cancellation method of this business in your area, I suggest you consult the local 100 10.
