How to unlock iphone for free to use on another country?

I'm using iphone 4 with ios 7.0.2 and it is locked with AT&T. How can i unlock it?

You have to have an international unlocked iPhone purchased at retail price. It's technically illegal now to unlock phones and transfer them to other carriers unless it is an international unlocked phone.

Contact AT&T and ask them to unlock it (may cost $) usually they will be happy to help
