Hi,I am currently on Airtel's Home 999 plus broadband plan. I am now getting a second broadband connection from a different ISP. I want to keep my existing Airtel connection as backup. I therefore want to switch to cheapest possible plan of Airtel. Please suggest the plan I should switch to. I am in Delhi region.BTW, I looked up tariffs on Airtel website. Looks like Rs 499 plan is cheapest. Is there anything cheaper available?Waiting for your replies!
