China Mobile sent a text message saying that it can exchange points for money. I filled in the bank card account number, ID card, bank card password and mobile phone. But my card has no money.

It is best to change all your bank card passwords, as well as the passwords of online banking or Alipay. It's best to change the bound confidential mobile phone number just in case. After all, as long as you know the number now, it is easy to copy whether it is a bank card, an ID card or a mobile phone card. If something goes wrong, the bank won't care about you.
