How to Check or Find CSC on Samsung Devices
You can check the CSC of your Galaxy device by dialing a code on your device’s dialer itself. The secret code you need to dial is *#1234#
NOTE: COUNTRY CODE will changed automatically. (for Same Muti CSC: code )
my country is "THL" but the same Multi CSC code "OLM"
Since I flashed the OLM1 (Multi-CSC) firmware and switched to THL (Thailand) CSC, it shows me both the CSCs. In the 3rd line, you can see the activated CSC, that is THL. This simply means that I’ll keep getting official OTA updates.
Now, let’s come to the 3rd line in the above screenshot:
THL(1)/
THL(2)/
THL(3).
- The first CSC value, that is THL in my case, shows the active CSC. This determines the access to services and updates. You will receive updates on this channel. This is also the country used for Samsung’s Beta programs in case you want to join one.
- The second value ITHL” shows that my Galaxy Tab A7 Lite is a One-SIM variant. This value only shows what SIM you have inside, and doesn’t affect any aspect of the experience.
- The 3rd CSC value, that is THL again, shows the country code for which the Samsung device has been manufactured and configured. This one cannot be changed and it doesn’t need to. In case you get the phone from a carrier, this value will have the locked CSC code. In case the other values don’t match, your carrier can refuse warranty service (since warranty goes through the carrier in case you’re on a contract.
