Hi,
Sorry you are having issues with your new Apple ID.
First, log into the Apple ID website https://appleid.apple.com/ and then go to Payment Methods.
Confirm you have a billing and shipping address listed, regardless if you are putting a payment method on file.
Confirm you include your phone number in the billing address as well; this is very important when creating your Apple ID.
Afterwards, on your device Settings > Name > Media & Purchases > confirm it does not say ‘OFF’. If it does, tap ‘Off’ and then ‘Continue’ on the pop-up.
Now, go to the App Store, click on your Profile/Avatar in the upper right hand corner > if you are signed in, tap sign out at the bottom.
Search for a free app > tap ‘Get’ > it will then prompt you to sign in with your Apple ID > select use existing Apple ID
You should then receive a pop-up stating the Apple ID has not yet been used/reviewed in the iTS > Tap Review > Confirm your correct country/region > swipe green/enable the T&C > press Next > enter or confirm your billing address once more on this page, and include your phone number > press next > you should receive another pop-up that says ‘Apple ID creation is complete.’
This should resolve your issue.
Note: expiration dates of cards need to include the full four digit year when adding a card to your Apple ID.
