How to Network unlock AT&T GoPhone Samsung A157

Luckily, I had an AT&T goPhone lying around after I bought Samsung Galaxy S3, but it was locked to AT&T alone. I tried to insert my airtel sim, but it asked for Network lock pin.
After searching for a solution for a long time, I finally found the solution from
here
