Bsnl is most popular connection in India and Bsnl is the only Government company who is giving the competition to private broadband companies But BSNL is very terrible company for service and Internet connectivity. Internet servers of BSNL are very poor it always showing network error while using Internet and gives very slow speed. You can not trust on BSNL connectivity. Connections are very poor even in big cities. Coustmer care are very lazy and they works like snails. Service is also very poor afterall it is a goverment company.
So Do not use BSNL brand you will be frustrated.
