Quick facts:
a) India has recently surpassed 1 BILLION cell phones in use which is 40x the number of their landlines!
b) The cell phone coverage and reception is pretty darn good across most of the country (except for some remote rural areas) and the rates per minute are among the cheapest in the world.
Here's the deal:
Follow these tips below to learn how to get a SIM card (without getting scammed), what the going rates are, how to recharge your plan and which phone you should use.

There are several good reasons, such as to:
There are of course a million other reasons that you could need a cell phone but you get the idea.

Also, it is best to get a local SIM card so you will require an unlocked phone that can take new SIM cards. I've listed a few of my suggested phones below.
If you're wondering, "what the heck is a SIM card?!" — it's the little chip inside a phone that connects to your provider (pictured at the top of this page). In the US the service providers typically lock them into the phone so you can't easily change carriers. As far as I know, almost all other countries have phones that are unlocked.
I have a phone I use specifically for my India trips because I'm not going to take my $900 iPhone. This brings me peace of mind and assurance that I'm not about to waste a ton of money if it gets lost or stolen. Although, that's what travel insurance is for 🙂
Here are a few good (affordable) options that I recommend:

Often times you'll also need to show proof of your Indian address which can be a letter from your hotel manager. Additionally, you may be asked for proof of your home address which could be a copy of your driver's license.
I know, this is pretty strict but they say it is to help curb terrorists using cell phones in India...

If you don't manage to get one from the airport then the next best option is to go to an official office of one of the top service providers such as Airtel, Vodafone or Reliance. These can be found in every major city across India. If in doubt ask your hotel to help you organize it.
One thing to note is that it can take a while for them to verify your address and you should insist that they do because otherwise the SIM will "magically" be turned off after just a few weeks of service!
You can recharge your SIM card minutes or data at any participating vendor on the street that is displaying your service provider's logo. Make sure you see that your phone actually recharges while you're in the shop in order to avoid getting scammed.

The convenience of having 3G mobile Internet is pretty epic when you're in outback India checking Facebook while on a train but it can get expensive fast if you're doing a lot of work.
In this case, you may be better off to get a 3G Dongle that connects via USB to your laptop. The same documentation as above will be needed for getting your hands on one of those suckers.

I have had the best experience and coverage with Airtel and Vodafone. Although, all of them seem to have quite terrible customer service so be warned and be patient.
In the picture above you can see a couple of friends of mine when we set up an office in India for a working holiday there.
Usually a Simcard will stop working after 3 months of inactivity. They claim this is to stop terrorism. It is a bit annoying if you plan to come back next year.
One way around it is to lend it to your friends who may be going to India within the 3 months after you get back.
Typically you should expect that you'll need a new SIM card every time you go to India.
