Hello there.! Guyz I have Airtel Broadband connection & the speed and service is awesome. Even the quota is over(like mine is 20GB), it still provide pretty good speed, I can still watch youtube video online easily. The broadband Pack you choose is the main role player. And yes during setting up broadband they charge just Rs.1000 /-(including pack charge & modem) and gave us TENDA-Router and said that if we uses it for 6-months, then the Router will be ours.So, if we dont want their connection, they will allow us to keep the router.
(Although Im pretty sure that, Im not going to discontinue the service).
