Bank of China, why can others receive my medical insurance card text message?

1. The mobile phone number you used was reserved by the previous owner for social security and medical insurance information. When the former owner stopped using this mobile phone number, he did not go to the relevant department to modify the reserved mobile phone number.

2, the social security department's work mistakes, with the current computer operating system, this situation generally does not appear, because when you want to handle the information notification, you generally need to receive the mobile phone number of the information notification for SMS verification, and it is a secondary verification, that is, you have to send the information input verification code twice to successfully handle it.
