I just got a mobile phone number, a number that others have used before, a bank card, and information with consumption records all the time. Can I cancel it?

How come... Usually such numbers will be eliminated. You can ask customer service As long as it is officially handled in the mobile business hall with its own ID card, there is no problem. When handling a mobile phone card, you should keep the signed card handling agreement, and pay attention to releasing all kinds of bindings before changing the mobile phone number, otherwise there will be security risks such as information leakage.

Go to the business hall and ask it to cancel the binding business that does not belong to you. At the same time, you can complain and demand compensation. If what you said is handled through the formal channels of the business hall, you can claim part of the phone bill.

Take my ID card directly to the business hall of the communication agency to which the nearest mobile phone card belongs, and cancel the binding business that does not belong to you.
