A wireless communication network serves a wireless data service to a wireless User Equipment (UE). In the wireless communication network, a network controller receives a service request from the wireless UE. The network controller responsively indicates the service request to a Unified Data Management (UDM). The UDM receives the indication. The UDM identifies provisioned service values for the wireless UE. The UDM retrieves updated service values for the wireless UE. The UDM identifies a set of the provisioned service values that correspond to the updated service values. The UDM generates new provisioned service values by overriding the set of the provisioned service values based on the updated service values. The UDM transfers new provisioned service values to the network controller. The network controller receives the new provisioned service values. The network controller serves the wireless UE based on the new provisioned service values.
