You have to pay. You can cancel your account in the mobile business hall with your ID card, but you should pay attention to the phone bill you owe. Account cancellation refers to the process and result that a member (registered user) no longer accepts an agreement or uses the services provided by a party (service provider) to the member (registered user), but terminates an agreement and deletes the member account number (ID). Telephone charges usually refer to the prepaid expenses of mobile phones. When the phone bill balance is insufficient, it will cause downtime, which will cause the service provider to be unable to continue to provide services to users and use mobile phones.
