i am from INDIA here are few little tips for you .
if you want local sim for long term , then please don't go for paper work.
simply go to a local vendor who is selling sims on road side etc . ask him for help ( use a little social engineering here /) he will provide you a sim for around 2-3 $ with a forged document .
please note :- this is illegal but it is too common in market ( i never saw anyone having trouble because of this )
my experience with creating account here :- use can use upto 7 accounts per ip with no issue BUT it depend on what you do with these account
This tip will save you a lot money
if you are coming to INDIA you will surely love to visit different tourist places
but when You go to ticket counter you will amaze to see the price different for ticket for different people
ticket for indian student :- rs 10
ticket for india adult :- rs 100
ticket for foreigner student :- rs 25
BUT TICKET FOR FOREIGNER ADULT :- rs200
so if you had a student card id from collage or university , take it with you
You will get discount in traveling etc with student id
please note i only tell you the average ticket price of tourist place for RAJASTHAN _ INDIA
it may very from state to state
