How can I remove my credit card number from the phone
iPhone 5s, iOS 9.3.2
If you mean remove it from your iTunes account then log into the account and see if you get the 'none' option : Change or remove your Apple ID payment information - Apple Support
That's what I was looking for and it doesn't show any. I even tried to reboot change settings aand still nothing. I didn't have this problem before but for some reason it doesn't have it anymore
By 'doesn't show any' do you mean it's not showing the 'none' option on your account, not showing your card details on your account, or something else ?
If the 'none' option : Why can’t I select None when I edit my Apple ID payment information? - Apple Support
