Is it true that the Bank of Communications sent a text message saying that the bank card was locked?

If it's a dedicated phone of Bank of Communications, I'll send you a text message, which may be true, because their phone number is unique, and others can't send it backwards. If you're not sure, it's easy. You can directly bind the Bank of Communications card with your mobile phone and try to transfer money. If you can move it, it's not locked. If you can't move it, it is locked. Another way is to call customer service directly.
