To sum up after subscribing both for years.

Inferior 3G coverage compared to Celcom 3G. I went to small towns and could not get Maxis3g but my Celcom showing coverage bars – (i.e Durian Tunggal – Melaka, Mersing – Johor). When I am not away from my wired broadband, I use Maxis3g to download (direct download ISOs and Movies) You can leave it on and download using download applications and you can get full speed. Well as for Celcom 3G you can download at full speed if there is activity on your browser – That means you need to surf certain sites and the download progress will move. If you leave it on and download using download manager only, the connection will drop tremendously. I am not happy. I guess I will terminate my Celcom3g and keep my maxis for downloading big files. I don’t really like surfing using 3g or hsdpa because of the latency. It is not stable unless you get full bar coverage and near the transmission tower. I am very positive that Maxis will beef up their coverage by erecting more towers. And the winner is Maxis3G.

P/s This is direct download not using torrent.
