Techniques for network subscriber management. These techniques include establishing a first virtual private network (VPN) connection between a first base station and a VPN host and a second VPN connection between a second base station and the VPN host. The techniques further include receiving a request at the first base station from a first mobile device and determining, using the first VPN connection, that the first mobile device does not have a recognized associated identifier, and in response assigning a mobile subscriber identifier. The techniques further include routing a first cellular communication from the first base station to the first mobile device using the identifier, receiving a second cellular communication at the first base station from the first mobile device, and routing the second cellular communication to at least one of: (i) the second base station using the second VPN connection or (ii) an external communication network.
