Well well! Let's have a look at the DiGi HSDPA connection @ Tanjung Sepat area.

From the figure above, as you can see you will get a 'my grandmother can run faster than that' connection when you are connected to that site with cell id 11401 and 11403. This means that either you are in Jalan Besar or Jalan Dua or certain area in Jalan Tepi Laut, you might get this crappy connection (the slowest among the telco in the area) from DiGi.
Let's dive into the 3G area,

You should get a 3G connection when you are connected to these sites which is out of town center (gosh what is on their mind?)

Anyway, you should get a better 3G connection when you are in the lovers' bridge and certain area in Jalan Tepi Laut as long as you can get connected to these sites and the connection is not stable.
Finally, let's compare the speed between a landline and the 3G connection.

The above figure shown the speed of downloading using DiGi HSDPA network. Not bad but still have space for improvement.

and let's see my own landline claimed to be 4mbps...
Thank you for reading. :-)
