@danjoy42: SIM cards contain a temporary placeholder number before your own number is added by your mobile network provider. On occasion, this can cause a read error in Settings > About Phone, causing it to show as 'Unknown' or, in your case, to show the default number. Typically this doesn't affect your network capabilities in any way, however you may wish to contact your network to request a SIM swap to see if this resolves the issue.
