I believe the results are based on average speeds throughout Malaysia. Bear in mind though that majority of U Mobile users are in Klang Valley only while other areas are usually using the other big three telcos. No to forget that the user base for the big three is bigger as well so that can be another factor when speed test results are based on average.

I'm always on the move and have used Maxis and Celcom before. I cannot deny that Maxis' 4G network is pretty stable among the telcos in Malaysia while Celcom's plan is much more affordable and offers a strong 3G network.
