BSNL
has announced a special Diwali bonus scheme for all the BSNL Broadband
users who have been active with BSNL Broadband for the past six months
and have used it till the end of November without any breakage in
service or stoppage, etc.

With this offer of Deepavali Bonus,
all the existing BSNL Broadband users can actually get double usage
from their existing broadband plans for the month of November. That is,
you can download twice the amount of total download limit implied on
your plan.

For example if you have a plan with 1 GB of download
or upload limit, then with this offer, during the month of November,
you can download/upload up to 2 GB with the same plan charges. Hence,
virtually you will be getting 1 GB free download. Similarly you can get
it for all other limited plans with BSNL Broadband. Obviously this will
not be applicable for the unlimited usage plans with BSNL.

This
offer is valid only for the month of November. No plan changes will be
entertained during this month and all the plan changes will happen only
during the month of December.

The only pre-condition, as far as
I know or I can comprehend, is that you should have been the BSNL
Broadband customer for the past six months.

This plan is valid
in the Maharashtra Circle, Punjab, Bangalore and Chennai Circle as far
as I know and must be applicable for the other BSNL circles too, not
sure. You must check with your BSNL office or BSNL helpline at 1500
(available only at select cities) to confirm the same before you start
with your usage. Those who know other cities in which this offer is
applicable can mention the same in the comment section of this post.
