My Experience using Indosat IM2 Broom Unlimited Extra

I was using "Indosat IM2 Broom Unlimited Extra", approximately about six months ago, at first i was just using on my home and i feel disappointed about the result because I was using GSM Modem that already support HSDPA (High Speed Downlink Access packet) 3.6Mb/s, so logically, I ought to get 3.6Mb/s whenever i connect to the Internet, but  I just only get 280 Kb/s.

-So the download speed approximately with speed 280 Kb/s  just only 8KB/s, and this was right, as addition my connection was detected as "EDGE INDOSAT",  back then I presumed this was caused my home was located on the suburb.

But I have the different story when  I try to connect in Jakarta, wow my status as HSDPA was detected, and the speed that I got was "3.6Mb/s", and the download speed around 20KB/s - 30KB/s.

The POINT that I want to share was, I take my gsm modem with same configuration to Bandung, my home, I'am surprised, Why ?, cause my download speed still around 20KB - 30KB, but when i redialed the connection, my status was reset to "EDGE INDOSAT" with  maximum download speed just only 10KB/s.

Wow, Is this conspiracy ?, haa haa ha, kidding !. But the point,  that was my experience, all of you got another experience?. just spit the words !!!!
