What does it mean that ICBC tries to read short messages?

Just need your phone's permission. Because when operating mobile banking, the bank will send a verification message to the card owner when it needs verification. If the mobile phone allows ICBC mobile banking to read the message, the verification code will be automatically written into the verification information column; If the mobile phone prohibits ICBC mobile banking from reading short messages, then the user needs to manually enter the verification code in the verification information column.
