But it's not, because some carriers explicitly don't allow eSIM transfers, or reuse of the initial QR code, or even the forced generation of a new eSIM without either customer support manually revoking the previous one, or deleting it yourself from the old device. I think the problem here is: there's no consistent regulation on how a replacement eSIM can be provisioned on a new device.
