Why does ICBC send me a text message when someone transfers money to my postal account?

Two possibilities. When someone else transfers money to Postal Bank, sometimes the text message will not be received immediately, especially on holidays. At this time, there happens to be an account change in your ICBC account, so you receive the ICBC text message. Another possibility is that the other party simply transferred the money to your ICBC account. In short, you will never receive a text message notification from ICBC for changes in your postal account
