How to create apple id witnout giving credit card details in iphone 5s?

I can't download any apps in my iphone because every time it is asking credit card details (which i can't give) without which i'm not able to proceed… Please help… I asked other people using i phone but they told they didn't find any problm with that…

I'm not sure if this still works, but this is how I made mine without a credit card. Make one through your iPhone. Go to the App Store, and create a new ID. You can make one, and it won't ask for your credit card if you make one through your phone.

There's an option for "none" in that screen, so yo udont have to enter a credit card.
