Can i unlock at&t locked iphone 5s next day after purchase?

I wanted to know if i can unlock iphone 5s that i buy with a contract with at&t coz contracted iphone costs only $199 that is nothing for an iphone.
so is it possible to unlock an undercontract iphone locked on at&t & used in india on any carriers?

No, You can't do this because Unlocking is an software process and it will take time because unlocking is not avail in market right know. It will take a week or two.
