BSNL is low power broadband I have so much experience and I use it for 3 years so lets stared. BSNL service and support is good but their inter net is not good inter net speed if you have 1 MB per second you your net have 500 KB per second its connection so low in my house network connection is not full so low its internet speed is so low its reliability is ok but its connection is not good I not suggest BSNL.
