@Caro11 you shouldn't delete it. Please check again on the Sim Manager screen, or Settings >Cellular and see if the esim is there.
Usually, you have to pay $5 to re-buy a new esim if you have deleted it, but since it is a new activation, maybe support staff can help. Please message them and see if they can generate a new one for you:
