Im using BSNL broad band from 2009 onwards.Therefore, I assure that my review is a honest review.
1)Price wise and service wise, it is OK.If any service complaint is there, they will rectify it within 1 day.
2)Also, they give many freebies-i.e, sunday unlimited free calling, free calling every day after 9pm.
The only one thing, I disliked about them, was that that their some advertisements were couched in vague language.
