In this guide, we will show you the steps to change the CSC to a US carrier on your Galaxy S23 Ultra. There exists quite a few customized firmware for the US region of the Samsung flagships. However, most of them require you to be on a US carrier as well. So even though you might not need to change the Country Specific Code, the firmware might still require you to change the carrier.
In this regard, we stumbled upon a nifty module that should help you get this job done. However, simply flashing this mod wouldn’t be enough. You’ll also have to get hold of a terminal app for your device which will then be used to execute a few commands that will make the module up and running and in turn allow you to change the CSC to a US carrier on your Galaxy S23 Ultra. So without any further ado, let’s get started.

Please take a backup of all the data on your device, just to be on the safer side. Droidwin and its members wouldn’t be held responsible in case of a thermonuclear war, your alarm doesn’t wake you up, or if anything happens to your device and data by performing the below steps.
- To begin with, root your device via Magisk Patched AP or TWRP
- Then download the S23_CSC_Changer module onto your device.
- Now launch Magisk, go to Modules, select the mod, and hit OK.
- The module will now be flashed. Once done, hit Reboot.
- Once your device restarts, download and install Termux from Play Store.
- Now launch it, type in su, and hit Grant in the Magisk prompt.

- You’ll now have to choose your carrier CSC code. For instance, type in vzw for Verizon.
