BSNL 3G review and speed Test
Speed:
The upload and download speeds were acceptable compared to the advertised speeds. The speed of the connection highly depends on the network strength, simultaneous number of users connected and any interferences.
While indoor the speeds were around the 1.5 Mbps mark. The video below was recorded on my terrace around 8 PM in the night.
As can be seen the speed is pretty impressive.
Coverage:
The network coverage also is pretty good. I was able to get strong signals even in the outskirts of pondicherry. On the entire stretch from Pondicherry to Chennai there were only a few places without 3G signals. Still you will have the 2.5G EDGE network to fall back in these situations.

BSNL 3G configuration
First confirm your handset is 3G capable.
Automatic configuration:
Send a SMS to 58355 in the following format:
MAKE MODEL
eg: For my N900 the message to be sent will be :
NOKIA N900
You should receive a series of Configuration SMS messages . Accept them with PIN 1111
Now you must be all set to use the 3G network. When you are connected to the network your signal level indicator should be ideally showing 3.5 G indicating you are connected at 3G speeds.
If not cross check whether your network mode under Settings->Network is set to 3G or DUAL or something similar.
Manual Configuration (Which worked for me).
Create a New Access point with access point name as : bsnlnet
All other configuration details can be left blank.
This worked like a charm for me.
