YouTube playback test over a SIM
Stream a YouTube video over the SIM's data connection and measure playback quality: start time, buffering, dropped frames.
The closest measurement to what a subscriber feels when watching video on the network. You get the time before playback starts, how often and how long the video stalls to buffer, the frames dropped, and the quality actually reached versus the best available.

Plus the shared connection settings.
