Just looking at the code SM-S721B/DS, can we conclude that this is an international version or do we still need to check the CSC to know exactly which country the device is distributed in?
Through the image of the device, we can identify this as Samsung Galaxy S24 FE with model code SM-S721B/DS, supports two SIMs and has eSIM through the EID displayed on the device. However, SM-S721B/DS is not a country-specific code but is the hardware code of the international version distributed by Samsung in many different markets.
This means that the two Galaxy S24 FEs both carry the code SM-S721B/DS, but one can be sold officially in Vietnam, the other is distributed in Thailand, Malaysia, Singapore or Europe. The actual country of distribution is determined by the CSC Country Specific Code, not by the model.

Samsung also releases separate firmware for each CSC. For example, the same model SM-S721B but has firmware for Vietnam's CSC XXV and Europe's EUX, showing that the model does not determine the distribution country.
Want to determine the exact modelWhich market this Galaxy S24 FE belongs to needs to see CSC in one of two ways
* Go to Settings → Software information → Service provider's software version
* Or enter code *#1234# on the call keypad and see the CSC line
Conclusion
From pictures can verify
* Galaxy S24 FE
* Model SM-S721B/DS
* Dual SIM international version
* Has eSIM support
However, it is impossible to determine whether this is a Vietnamese, Thai, Malaysian, Singaporean or European device without CSC. Therefore, concluding the country of origin based only on model SM-S721B/DS is inaccurate and inconsistent with the information published by Samsung as well as the firmware system of each CSC.
