What should I do if my ID card is fraudulently used by Unicom's business hall to handle business for others?

If this happens, it is recommended that you show the original information of your ID card, and the staff will inquire about the Unicom number you are bound to. If you steal your ID card information to handle business, you can apply for cancellation of Unicom number, and investigate the legal responsibility of those who steal or use your ID card number.
