Is it dangerous not to untie the bank card after canceling the mobile phone number?

The mobile phone number is cancelled, please unbind it all. Contact with the original account must be severed.

Many people will bind their mobile phone numbers to various accounts such as bank cards, Taobao accounts, Alipay and WeChat. If these numbers are abandoned and sold to others, these accounts will be in danger.

Whether a number is bound to bank card, Alipay, other website accounts, etc. These are all user privacy. As a telecom operator, it is impossible to find it in the background, and it is impossible to help users change or empty personal information uploaded to the network when canceling the number.

Therefore, before deciding to cancel a mobile phone number, you must unbind all other accounts to ensure the safety of personal information.

The mobile phone has changed its number, so there is no danger of unbinding the bank card.

First: if the bank card is bound to the mobile phone, it has not been cancelled, and the account has no balance, which will actually cost the user a lot of money. Because bank cards are not free, many people often think that they are free if they don't mention cash.

In fact, there are other fees for bank cards. If you don't cancel your bank card in time, you may have to bear considerable debts after more than ten years. At that time, if we refuse to repay them, our personal credit will be affected.

Second: if the bank card is the main card, once its balance becomes negative, it means that we can't handle other bank card business, which will actually bring a lot of trouble to our daily life.

Therefore, it is necessary to check the bank card balance regularly and make a reasonable management plan. If you feel inconvenient, you can also bind all bank cards to Alipay and WeChat, and save some cash in time to avoid the difficulty of selling cancelled films in different places.
