What does it mean that the Bank of China sends a message that the bank card is suspected of being used for illegal and criminal activities?

Don't trust this kind of message easily.

Bank of China will not easily send out the message that it is illegal and criminal. In this case, it is necessary to call the bank's customer service hotline and consult the bank.

Generally, China Bank will use 95566 or 106980095566 to send text messages. Among them, 95566 is used to send non-marketing short messages, and 106980095566 is used to send various marketing short messages. If you receive a short message such as collection, you can ignore it. It is sent by the collection outsourcing company. However, if you really have related business, I suggest you directly consult the online customer service of Bank of China. If you have other business needs, you can also choose to download the mobile banking APP of Bank of China or follow "Bank of China Weizhong Bank" on WeChat to continue consulting and handling related business.
