Question about Galaxy S20 FE 5G EU - 539494

1) For this model, what does the "UE" mean? And is it an advantage, or a disadvantage? 2) And again for this model, I wanted to make sure it has dual sim AND a separate memory card slot? 3) Again for this model, is/will the e-sim be available, as standard, or as an option? Or would another model have this (and the other features (5G, dual sim AND separate memory card slot). 4) Is there a 5G S21 or S22 FE with dual sim AND a separate memory card slot: it's always hard to tell from the descriptions (not c/o digitec, I think).
