How should Unicom replenish the card or stop?

You can log on to the homepage of Unicom's online business hall, click: self-service > business handling > shutdown service > shutdown number/restart, and select the corresponding type to handle shutdown business, which will take effect immediately. Or you can go to our own business hall with your service password or valid ID. In order to protect the owner's rights and interests, at present, only the card replacement business in different places is supported, and other businesses can only be handled through their business halls. You can bring valid documents to the local business hall that supports cross-regional card replacement for consultation.
