Various arrangements for operating a cellular network with advanced secondary operator privacy are presented herein. A first set of user equipment may communicate using a first radio unit and a first radio spectrum with a cellular network. A second set of user equipment may communicate with the cellular network using a second radio unit and a second radio spectrum. The second radio unit may be operated by a secondary operator distinct from the cellular network operator. The second radio unit may encrypt the second communications such that the cellular network cannot decrypt the second communications. The cellular network, can route the encrypted second communications of the second cellular network slice from the second radio unit to a data center operated by the secondary operator separate and distinct from the cellular network.
