I agree it is not optional. If we could find a identifier on the SIM certain to be unique, we could allow the user to set the phone number for each SIM, as we allow a name to be set for each SIM.
Edit SIM details -> [name] [phone number]
We then tie this to the subscriber number (if guaranteed to exist on all SIMs and be unique).
