Q: i dont have a credit card

Hey aplove,

Welcome to Apple Support Communities.

From what I gather, you would like to sign in to the iTunes Store without entering credit card information.

Take a look at the article linked below which will walk you through the process of setting up your Apple ID without a payment method.

Create an iTunes Store, App Store, or iBooks Store account without a credit card or other payment method - Apple Support

Cheers,
