I have a zte 4g lte from metro with the 40 dollar plan and when trying to watch youtube videos I cannot watch them they either don't load or they load but lag a lot. I recently downloaded speed test app and the results were ping: 100 download 0.20 upload 0.29. I don't know what the average is. I don't know what the problem is.

need more like 1.0 mbps+ to watch without constant buffering. And if you're on a 500mb plan, you're going to use that up really quick with video/audio streaming.
