How to download apps on my iPhone?

I got iPhone 4S but I'm unable to install any app or a game. When I try to do so, they ask for the review of apple Id… I have created apple ID but in review, they ask for credit card. I don't have any thing like that I'm also unable to download free apps.

Basically, create an account. When it asks for a credit card, click "type" and select "none"

Choose none as an option for credit card
