I would like to find out is this cellphone second hand or it is brand new?

Based on the search results, it appears the Samsung Galaxy S21 Ultra 5G Black for R24499 and the Samsung Galaxy S21 Ultra 5G 256GB Dual Sim Phantom Silver Demo for R13499 are both likely to be brand new phones. The Black model for R24499 doesn't specify if it's new or used, but selling at full retail price suggests it's brand new. The Silver model specifies it's a "Demo" unit, but at a discounted price, so it was probably a display model. The other results seem to be accessories like cases and camera lenses rather than the phone itself. Let me know if you need any other details on these phones or have additional questions!
