Bsnl is only network run by Government of India. The network coverage of Bsnl is very wide.We can also connect or call while travelling in train in a remote location where there is no coverage of other networks.Coming to offers bsnl does not provide or lure it’s customers with much offers.They should consider this and one of the drawback of Bsnl is validity of prepaid recharge.They should make it for a lifetime as compared from other telecom vendors .Charges are normal as others.Interms of coverage it’s one of the best network.
