How do I remove my phone number from the settings>phone ID>phone number page?
I am trying to sell my phone, but don't want that to be there

Prior to selling, doing a hard reset i.e. restore all setting to factory default shoudl remove that, but it will remove everything, all apps downloaded all messages, contacts, everything.
