Will a iphone 5s bought from US work in india with vodafone sim card?

I'm going to US next week anddm thing of buying iphone 5s from there as it is cheaper compared to india! So if i buy a 5s from there will it work here in india? And what type of 5s do i have to buy and where will i be able to buy it?

Hope when you say its cheaper that you aren't looking at the $199, 299, 399 prices because those are for 2 year contracts, open to Americans only. You'd have to pay for the unlocked models which are $649, 749, 849.

Those will work with any SIM card in the world.

In simple words it works only if it is factory unlocked!

Buy an iphone 5 on contract. Before going back to India visit in Apple's franchise nearest you and tell them I have to go India for few months and I want to use Iphone there. They will recharge you $45 to $60 and your device will be unlocked.
