In this guide, we will show you the steps to enable the Dual SIM Manager on Samsung Galaxy devices being sold in the US. The devices from the South Korean conglomerate have encapsulated the attention of the masses, across the budget, high-end, and flagship domains. If we talk about the latter one, then the S series has quickly become the go-to choice for users.
Among all the regions, it is safe to say that the users in the US are the major dominant factor in pushing its sales number to new heights. However, they have to deal with a rather infuriating issue- you cannot assign different SIM cards to calls/messages and mobile data. At the very most, you can “Use your secondary SIM for mobile data if your primary SIM can’t connect”, however, there’s no mention of LTE/5G.
This is in stark contrast to the International versions wherein you can designate different SIM cards for different purposes right from the SIM Manager menu. So is there a way out? Well, there does exist a nifty workaround that should help you address this missing piece of the jigsaw. So without further ado, let’s check it out.

How to Enable Dual SIM Manager in US Samsung Devices
We have listed two different methods that will help you get this job done. Go through each of them once and then try out the one that is in sync with your requirements. Moreover, before starting please take a backup of all the data on your device.

METHOD 1: Switch to GCF CSC
Change your CSC to GCF [Global Certificate Forum] using the SamFW Tool. However, the drawback is that the OTA updates will be disabled. You will have to change it back to a working CSC (such as VZW or USA) to allow OTA update, or manually flash the firmware via Odin.
METHOD 2: Flash PCT Firmware
You can also flash the PCT [Puerto Rico] U1 firmware on your phone. It will enable the Dual SIM Manager similar to the one that you get on the Global version. However, the OTA updates will be slower than the US counterpart.
Once you have applied either of the two above fixes, you’ll also have to execute an ADB command to make the new CSC code stick. If you don’t do so, then the device will shortly revert to the old CSC. So. proceed with the below steps to implement this fix as well:
- To begin with, download and extract Android SDK Platform Tools on your PC.
- Then enable USB Debugging on your device and connect it to PC via USB cable.
- After that, open Command Prompt inside the platform-tools folder and type in:
adb shell pm disable-user --user 0 com.samsung.android.cidmanager
- The Dual SIM Manager is now enabled on the US-based Samsung Galaxy device.
Do note that in some cases, you might still get the old SIM manager menu even after carrying out the aforementioned tweak. That is completely normal and you can easily switch between the SIMs and allocate different tasks to them right from the notification panel as well, as shown in the screenshot above. So on that note, we round off this guide. If you have any queries concerning the aforementioned steps, do let us know in the comments. We will get back to you at the earliest.
