Providers supporting esim on FP4? (Belgium)

Hi all
I am with the Phonecoop in the UK and they didn’t know what I was talking about when I asked for the QR code to activate my eSim… They are looking into it though but haven’t come back yet. I do need the dual system because one of my Sims is for work, I didn’t exptect this to be an issue when I bought the FP4. It would have been helpful to point this out on the Fairphone website that the eSim might not be available, depending which network provider you are with.
