A wireless User Equipment (UE) controls a wireless data service that is received from a wireless communication network over a radio band. In the wireless UE, a radio wirelessly exchanges user data with the communication network over the radio band to receive the wireless data service. The radio wirelessly receives a communication performance metric from the wireless communication network over the radio band. The communication performance metric characterizes the wireless data service received by the wireless UE over the radio band. In the wireless UE, user circuitry translates the communication performance metric into a service instruction for the wireless UE over the radio band. The radio wirelessly transfers the service instruction for the wireless UE to the wireless communication network over the radio band. The wireless communication network modifies the wireless data service for the wireless UE responsive to the service instruction.
