I am leaving in a rented room and my landlord have airtel broadband connection I think he has subscribed 999 plan which has 12 gb 2 mbps and after that unlimited data at 512 kbps, He is sharing his connection with me after I have paid some amount .
I am using this connection since 1 month and I never face any problem, no connection lost, speed is always constant .
In 2 mbps I got almost 2.1 mbps every time never got speed like 1.8 or 1.6 its always above 2 mbps and after 12 gb the mentioned speed is or the secondary speed is 512 kbps but I get around 600 to 650 kbps all the time . This is the best thing I have discovered in any broadband services . yes airtel is little costly but provides a very amazing service .
And airtel broadband is present everywhere like bsnl .
so best service with great speed .more than what is mentioned,
