Icbc SMS authentication

Your U shield is a second-generation U shield. Is there a display screen on it? If there is, there is no need to open the SMS authentication function. This function is mainly aimed at password cards and a generation of U shield customers, mainly for safer trading operations. Sending the transaction password information to your mobile phone and then inputting it into the webpage should be completed within 30 seconds. Online banking shows that there is no registered mobile phone number, which proves that you have not enabled SMS authentication function and left no authenticated mobile phone number. Maybe what you told the staff is the balance change reminder function, which is different from SMS authentication.
