BSNL broadband service is very bad. Especially if we talk about its connection stability.Its connection stability is very poor. If your internet is not working then the support team will not help you at all. There are many problems with its service. If you talk about its internet speed, then it can give you decent internet speed.But its speed is very less as compared to other service providers. Nor do you get any help from the support team in this, so its service is very bad.
