Plan types:
Budget plans - These plans cost around Rs.250/- a month or less. They typically offer only 256kbps speeds and very limited data - you'll be lucky to get more than 1GB or more.
Mid-range - Costing between Rs.250/- to Rs.500/-, these plans give you a lot of flexibility with speeds between 256kbps and 24Mbit (ADSL2 only) and data anywhere between 1GB and 40GB.
"Unlimited" - Not all unlimited plans are same, so be wary of certain 'unlimited plans' - they often don't limit how much you can download, but either cap your speed (usually to just above dial-up) after a certain limit is reached, or they poll all the ISPs users and cap the highest users.
User types:
Clearly, the amount you can spend will shape what kind of broadband account you can get, but it's not as simple as just plugging in as much money as you can afford and hoping for the best result. It's just as important to work out what kind of user you are, and work backwards from there to determine which services really matter to you.
If you're a:
Web surfer - Go for a light (256/512kbps) plan. The most important thing for you isn't necessarily speed, or even data usage - it's the always-on nature of broadband.
VoIP user - Go for a mid-range plan, preferably high-speed. If your broadband's being used for lots of other things at the same time as you're making a VoIP call, you'll suffer from dropouts and poor voice quality on a low-speed line.
Family user - Get a mid-range plan - you'll have plenty of users to satisfy - with either a capped download rate or shaped plan, so you don't suddenly get any nasty additional download bills.
Gamer - Go for as high-speed a plan as you can afford. Low speed (and high latency) will kill you in gaming far faster than your opponents will.
Heavy Downloader - Go for a high-data plan - possibly even an "unlimited" plan., but you're better off with a slower plan with big data allowance than a plan where you'll rip through all your data in a matter of minutes.
