Unlike the Note 3, the CSC (Consumer Software Customization) otherwise known as the Regional Carrier menu is a hidden menu within the Samsung Device model lineup. This menu will show a listing of scripts in the phone, depicted by a 3 letter code and specific to the carriers which can be preloaded on your device. If your device is unlocked and you wish to use it with one of the specified carriers, you can insert your carrier specific SIM, access this menu and "INSTALL" the specific configured script for that carrier. The question is always asked... "What is the benefit?".
Answer: With smartphones, they are mini computers and not just your typical "telephone". As such, you have multiple settings which vary among carriers. As such, by configuring your device to be carrier specific, it will modify specific settings which are proprietary to that specific carrier. As an example, it will modify the APN details, update your network settings to reflect access to specific modems such as 3G, 4G, HSPA+ and LTE and will also brand the device with specific apps which have been preloaded and configured for that specific carrier such as a "My Account" app. These are just some of the things to name a few which implementation of the proper CSC settings will provide.
Samsung realized that tech savvy people have figured out how to access these menus and this has resulted in fixes implemented in OTA updates to hinder people from being able to do this. As such, you cannot use the typical dialpad entry to gain access to the menu but do have the ability through ROOTING your device. Unfortunately, a ROOT will most likely "void" your warranty so it's at the discretion of the "end user" whether or not the warranty is important.
Thank you to all who assisted and happy trails!

When you select a specific carrier and click reboot, the device will do a factory reset using the specific carrier settings you selected. I know the S4 will have the same regional menu but I'm curious as to whether or not I can access this through a dial pad sequence and if so, what the sequence would be.
Thanks in advance for any help which could be provided!
