I have to cancel all call barring but i have forgotten barring password what to do

Unfortunately, the only way to recover your phone barring password on your device is to perform a Factory Reset. This will wipe all of your phone's data to bring it back to its factory settings, thereby deleting the forgotten phone barring password.
