Why did my mobile phone receive a repayment message from China Bank for two consecutive months, reminding me that I have never applied for a card from China Bank?

You should go to the Bank of China to verify this kind of thing, and you should not take it lightly, because someone may have used a fake ID card to apply for a bank card with your name and ID number. Once this happens, you should immediately appeal to the bank and call the police. If you don't have a China Bank card in the bank verification, you will receive a fraudulent short message from the swindler and ignore it.
