Have an impact. Now mobile phone numbers are all real-name registration systems, which are bound to personal ID cards. If you forget to log off when not in use, resulting in arrears, the operator can locate the individual according to the identity of the number binding, and then join the operator's "blacklist". In the future, if you want to handle other business of this operator, you must pay the arrears before you can handle it. If the operator still "maliciously" refuses to pay by SMS, it may be included in the credit information system of the People's Bank of China.

Friendly reminder:

(1) Back up the phone book Some people have too many important customers in their phone address book, but they neglect to manage them until they throw away their old cards. In addition, it is best to save the old card after replacing the mobile phone card to avoid being used by others.

2 The mobile phone number does not need to be cancelled in time. Some friends directly abandon the old mobile phone card when they change their mobile phone numbers, thinking that they will automatically close and cancel as long as they are not used. In fact, although it will be cancelled automatically, it will take several months. During this period, the system will automatically deduct the monthly fee until it is cancelled. The mobile phone is connected with the user's credit. Please cancel in time so as to handle business or banking business in the future.

③ After changing the mobile phone number of the bank card, the passwords of various bank cards and credit cards should be modified as soon as possible. You can also log in to online banking to modify online banking account information and change your mobile phone number. If you have stopped selling numbers, you can only go to the bank business hall with your bank card and ID card.
