Hi all,My home is in Chennai where we have BSNL DataOne. But, I mostly stay at hostel in Vellore where I study.I got a slightly old PC for myself at my room (hostel) recently. I am looking for a cheap internet connection. Since I will be paying for it from my pocket money, I want it to be really really cheap, both initial cost and recurring monthly charges.Please tell me which will work out to be the cheap overall. I need less than 400 MB download per month or less than 200 hours per month. I think volume based plans will be beneficial. I don't care about the speeds as long as it is above 2KB/s (16kbps).My choices so far: BSNL dataone (but costs 350+250 a month min for 400mb and huge setup fee). How about airtel and tata. Do they have cheaper plans? How about Sify?Or, should I get airtel gprs? I currently have airtel pre-paid and with net on phone activated, but I couldn't figure out how to use it with computer.Thanks!Stan.
