Bharat Sanchar Nigam Limited is a Government organisation, which provides calls, sms and internet with lower prices as compared to other private Mobile Operator companies.
Another best thing is that it gives roaming free .
And further sometimes it becomes poor as internet speed slows down, other Network problems .
But I prefer BSNL as it takes tax which goes to govt for betterment and need of ours .
It is the only company in which we can have faith in .
