I was getting frustrated so I decided to revisit the thread which I followed before I subscribed to this service. This thread at tipidpc.com discusses issues about Sun broadband wireless, the 3G broadband solution offered by Sun Cellular. I was surprised by the uproar of the subscribers there. THE REASON? Sun Cellular capped the speeds to 640kbps, making their advertised speed of 2Mpbs virtually unattainable. They discovered this atrocity because a user named lightninglord2000 posted a software where you can find several infos about your wireless connection, these info include upload and download limits. This software is called MDMA, Mobile Data Monitoring Application, available through this website. His post about MDMA can be found here.
I myself tested how my connection is. MDMA did not need any installation and is packaged on a 30KB exe. Running it was infuriating, since I found out why a 10 KB file was a nightmare to upload:

You see that Uplink amount? A whopping 32 kbps. (that a small b so thats a bit, divide that amount by 8 to get the byte equivalent) What the heck is with that? a dial-up connection is gives more of a fight than my connection! And how can I achieve the advertised 2mbps connection if they limited my throughput to 640 kpbs?
So to SUN cellular, I suggest you get your act together because you are clearly insulting our intelligence with what your doing. Get it togethere, before it hits the fan.
