I’ve been using Airtel Broadband for a year now, and I seriously don’t have a complaint for them. Everything is working fine, stable. I have a 16 Mbps unlimited plan with 25GB of data. And the download speed doesn’t change vastly, it remains at a constant speed of 1.8-2 mbps. I’ve tried bsnl and tikona before, bsnl was giving me way too slow speed for the same price and tikona was giving me headaches. It also includes free unlimited landline calls, so there’s no bill, call local or STD, It’s unlimited. They also give you the wifi modem for free, they don’t take money for that. It’s yours. I personally suggest Airtel Broadband to all the people out there unless you have DEN, Hathaway Broadband which provide high speed at cheap rates.
