How does Unicom cancel caller ID?

If you need to cancel the caller ID service, it is suggested that you can go to your hometown Unicom's own business hall with the owner's valid certificate or contact the local manual customer service to cancel it for you. However, if your caller ID is included in the package, it is generally a free service, and you will not be charged for caller ID, so there is no need to cancel. If your caller ID is charged, the caller ID service in some packages is fixed and cannot be cancelled (such as New Power/Wanzhong Card/Ruyi Tong Tong Listening Package). I suggest you check it out. If you still can't solve the problem or have questions, you can contact the customer service of the place of origin to understand, and the policy of the place of origin shall prevail.
