The mobile phone didn't move, but someone used my number to call and send messages. What happened?

This may be a master, because your card may have been copied by someone close to you. Cards bought before 20 10 can be copied now. As long as you read your ki, you can use the same number as your card, but you can copy your card to show that it is a person who can approach you! Secondly, it is not difficult to solve this problem. You go to the mobile business hall and tell him that your card has been lost or reimbursed, and then tell him to reissue it (with your ID card). It is difficult to copy the card that is reissued in this way. As long as you pay attention, the card copied by others will be invalid.
