BSNL is one of the most known network running successfully in india. Network of bsnl is almost everywhere is present. since it is very popular as well as older network than many operators. I am using Airtel and bsnl in my phone. As i’d mentioned in my earlier review that airtel is very expensive but bsnl is exact opposite to that of it. As they provide cheaper rates in the manner of internet and calling facilities yet it is awesome. BUt it has one problem. 3g network of bsnl is not present everywher.and whenever we try to travel in trains or buses. network starts showing its weakness. Otherwise it is better than airtel in terms of cheaper call rates.
