A system for directly comparing on a service quality basis a plurality of wireless network services includes a vehicle containing a plurality of phones for different wireless networks and a fixed location for receiving calls from or transmitting calls to the vehicle. A call is initiated at the vehicle or fixed location, and a series of preselected messages are alternately transmitted between the vehicle and the fixed end through each of the networks with each message being quality graded with voice recognition software or data comparison techniques so that quality grades for each network are provided which can be combined and compared in various ways. The vehicle also includes a global positioning satellite system so that the vehicle location and speed can be tagged to each transmitted message to compare the relative quality of the networks within specific portions of the geographical area covered by the vehicle.
