BSNL is a very good network and used by a lot of members in this society and this the one of the first mobile operator used as land line and now mobiles and now 3G data usage. We can have a good signal every where without any interruption compared to other operators.
It provides high speed when the network is H+ and BSNL company has good plans but the best advantages of bsnl 3g is that it provide very good 3g packs at the very lowest rate.I advise other people if you wants to choose bsnl then just check with services working properly in your area are not otherwise if you have good signal it gives best speed service.
