Dear Sir,
After loging the "selfcare.sde.bsnl.co.in" the details of phone is ok but broad band details are not shown The present management the web site is very hopless plz coney this

If you are able to login then you should find it under My Services, it is sometimes slow so give it time, also see posts : How to Check Broadband Usage on BSNL SelfCare portal - New portal
