My girlfriend sends a text message to ICBC.

Hello, I suggest that you first go to the local People's Bank of China to get your personal credit report, and check whether there are fraudsters using your ID card to apply for a credit card. If so, please take timely measures; Secondly, he means that you haven't used your card for some time, so your credit limit has been lowered. In order to ensure the security of your card, you can ask the customer service of the working bank to confirm whether ICBC will send such short messages to customers when the card is not used for half a year. By the way, do you have a card in ICBC? I hope it will help you. You can ask me if you don't understand.
