How to reset the password by SMS after Qinghai Unicom users forget their passwords?

Qinghai Unicom users need to edit "MMCZ#6 digits" on their mobile phones and send them to 100 10 (for example, "MMCZ#762 130" is sent to "100/kloc-0");

After successful sending, users will receive a reply message "Dear users, please reply" MMCZ#XXXX (four-digit random password) "to confirm that your service password will be reset to XXXXXX (six-digit random password). Failure to reply means that the application has been cancelled;

After receiving the short message, the user replies to the short message "MMCZ#XXXX (four-digit random password)" and sends it to "10010";

After sending successfully, the user will receive a short message: "Your password has been successfully reset, please keep it safe."
