How to link my existing apple id with my iphone 5s by reviewing my id without credit card details?
I already have an apple id i created online.But when i sign in with it,i'm asked to review my details.But i don't want to add any credit card information but it seems to be compulsory and i'm not able to link my apple id to my iphone either.What can i do? I don't have any credit card.
iPhone 5s, iOS 7.0.4
