About Auroville, you guys are right! The net is not reliable but Jio is. If it's your first time visiting there, you won't be able to get a a smooth entry unless you are volunteering there! Unless you know people inside you won't be able to get the most out of your Auroville experience. That said I found this place where you can stay without any entry barriers, http://www.bluelotus.org.in
