Mobile change broadband password SMS

It is suggested that you send SMS directly to reset the broadband password: after sending CZKDSWMM to 10086, judge the number of broadband numbers corresponding to the mobile phone. If it is a broadband number, directly modify the password, and send a successful SMS reminder after successful modification; If there are multiple broadband numbers, a confirmation message "Dear users, please reply to the broadband account you want to modify" will be sent to the user. After the user replies, the system will automatically assign a random password, and if necessary, the user will send an instruction to modify the password.
