There is only one way to cancel the card now. You can only go to the local business hall, that is, the business hall where you open the card to cancel the mobile phone card. When canceling the card, you need to bring your ID card when opening it. Be careful, it's me.
You can apply for a new card at any time as long as you are sure that the old card has been cancelled successfully and there is no record of arrears.
The cancellation must be guaranteed to be completely cancelled, and the old card has been cut.
If the old card is used many times, the success rate of reapplication is very low, because bad credit is left behind. In this case, you have to wait at least half a year before you try to apply.
