If you are a BSNL Braodband subscriber you should have been checking your broadband usage details at the web link www.bbservice.bsnl.in for many months. But with effect from 21st August 2009, the link www.bbservice.bsnl.in will no longer work and broadband subscribers will have to check their usage details at the link
www.data.bsnl.in.
So, go to
www.data.bsnl.in in your browser and when the page loads, enter the username and password (the same you used to enter at bbservice.bsnl.in) in the login form and login.
When you are logged in, click on “My Services” tab and chose your “service name” as broadband from the drop down menu. The page reloads and then chose your account number and usage month from the drop down menu and click “search” button . You are done.
Your broadband usage details are shown in a clean manner which include the connection start and stop times, duration of the connection, data upload and download done and total usage details. These details can also be exported to excel using a link given at the bottom on this page.
