Ok. Title says it all.
I'm desperate! Please help... ;~;
Yes, you can if you register an account on pokemon.com.
If you are registered to the official Pokemon site, on October 20 they are sending unique codes for the demo on your e-mail. Be sure to tick the box that asks if you want emails from them or you will not receive a demo code. This works for every country, not just India.
Hope I helped!
