There are cases when mobile network codes are occupied not by mobile carriers, but government structures (military, railway, landline phone authorities), fixed and broadband internet providers, scientific organisations, etc. Some MCCMNCs belong to obsolete legal entities, acquired by other market players or went to bankruptcy, but codes are kept for a certain period for legacy purposes.
