Wind/Freedom Mobile has relied heavily on the use of these codes. It gives customers another way to access some functions of their accounts, and Public being a self-serve carrier would likely have customers benefit greatly from them. These codes can be tedious to type in and go through the varies menus that might be set up for a specific code, but the advantage to them is the fact that custmomers can do stuff such as checking balance, activate add-ons, apply top-ups, etc. without the need for an internet connection.
