Orange is a huge company that supports eSIMs already in their major markets. I'm not exactly sure about Romania, but this page does exist which leads me to believe they do support it. https://www.orange.ro/servicii/esim/

Based on my experience esim profiles are often not available for prepaid sim cards still.
