And what really matters with mobile service is the real world usage. Can you stream a video at an acceptable quality, share media, and load pages in a reasonable time? If the answer is yes then the speedtests are just trivia that's burning your data.
That is exactly it. I think we get hung up on a needless bit of competition around who or what can achieve the highest speed, when in reality this metric doesn't matter so much. What's important is how the network (or any product really, but in this case a mobile network) performs in real life when you are actually using it. Now how it performed on some speed test.
More importantly, what speed/throughput/capacity will it deliver with multiple people using it at peak times? What will the customer's actual experience be?
