Do I need to change my mobile phone service password after receiving SMS bombing?

If you change the password of the mobile phone service, it will be blown up in the address book. Before the address book was bombed, it proved that the mobile phone information had been leaked and the relevant information had been retrieved. Later, it was too late to change the service password, so as long as the mobile phone number was not changed, the address book would still be blown up. The bombed address book is generally due to credit problems, such as the expiration of online loans and the lack of credit. If you keep your credit in your life and arrange the repayment time of each loan reasonably, there will be no bombing of the address book.
