- Make sure you are signed into your account

- Verify payment method(s) and billing address as described in Add a payment method to your Apple ID - Apple Support . Items in red have problems.

- If you're using other Apple IDs with services such as Messages or the App Store, make sure those are signed in too.

Other things to try:

- Check that there isn't an issue with Apple's servers: Apple - Support - System Status

- Try restarting your device.

- Check your software is up to date.

If you still have questions or problems:

Select your country, then a product. If you don't see one that handles your issue then keep experimenting with selections until you reach one that gets you a chat session or a telephone call and get the representative to redirect you.
