Abstract: The described embodiments set forth techniques for diagnostic testing a wireless device configured for cellular wireless service. A test apparatus processes data logs obtained from the wireless device, categorizes observed cellular wireless functionality issues, and provides recommended actions for a service technician and/or a user to take. Exemplary cellular wireless issues include cellular wireless service connectivity, cellular voice call stability, and cellular eSIM profile installation and transfer failures. Recommended actions can include directing a user to contact a mobile network operator with particular observations, adjusting wireless device settings, repair of a wireless device component, updating wireless device software, or replacement of the wireless device.
