Because calling cards need real-name authentication, if the real-name authentication fails, it will have an impact on yourself, such as being included in the list of untrustworthy people, and it will be very troublesome to defend rights or conduct legal proceedings later.

In addition, if your calling card has a package or a fixed fee, it is not enough or you don't want to use it, you need to cancel it. If you can't cancel, it will also affect yourself.

Therefore, when helping others to apply for calling cards, they need to understand the relevant risks and consequences to ensure that their rights and interests are protected.
