Right, I've been thinking of changing to airtel from mtnl. Here are some queries I had:1) Is it true that Airtel have upgraded their plans and now their 256 kbps unlimited connection costs Rs. 599?2) Will I get double my connection speed at night regardless of what connection I choose?3) I have 3 airtel mobile connections at home. Is it true that they give you a certain percent off from your broadband connection (in money) if you have the same number (3) of airtel connections?4) How's airtel's service in Chanakya Puri, Delhi?Thanks for the help 🙂
