The BSNL(Bharat sanchar nigam limited) is the oldest and best service providers from past and they used to be a good at telicom services, but when coming to the internet services they provide are a bit of heavy and expencive. When we talk about the internet services they are very poor and soo lag.And the cost will be soo much and the speed will be like very slow like if u pay an amount of 800 u will only get 4mbps with an gb limit of 25 gb this is one of those tarrifs.When coming t connection and reliability its very poor some times at some places the signal it damn poor.And finally about the services and support it depends on the area and staff some times they would and some times they won’t.
