Why did you receive a text message from Ping An Securities?

Because this mobile phone number may have been used for Ping An Bank Card.

The text message received by the mobile phone is linked to the number. Since you didn't apply for Ping An Bank's card, it may be that someone else's credit card is overdue or loans overdue, and the contact information is your number (did you just buy your number), so once the relevant account number appears, the bank will send a reminder message according to this number without knowing it, so you will receive it. After the mobile phone number is cancelled, you can re-enter the market. Maybe someone changed their mobile phone and didn't go to the bank to change their contact information, or maybe someone simply didn't use the account and ignored the bank information.
