Frequently Asked Questions

What does SKErrorDomain-0 mean on an iPhone?
SKErrorDomain-0 is an Apple StoreKit error code that means an unknown error occurred during an App Store purchase or in-app transaction. It is a catch-all code when the system cannot identify a more specific cause. Common triggers include network issues, an expired payment method, an Apple ID authentication problem, or a temporary outage on Apple's servers.
Will I be charged if I get SKErrorDomain-0?
In most cases, no. When SKErrorDomain-0 appears, the purchase transaction typically fails before it is completed, so your payment method should not be charged. However, if you see an unexpected charge on your bank statement after the error, contact Apple Support immediately through reportaproblem.apple.com to request a refund.
Does SKErrorDomain-0 affect in-app purchases in games?
Yes. SKErrorDomain-0 can appear in any app that uses Apple's StoreKit framework to process payments, including games with in-app purchases. The fixes are the same: check your internet connection, verify your payment method in Settings, sign out and back in to your Apple ID, and make sure your iOS version is up to date.
Why do I keep getting SKErrorDomain-0 after updating my payment info?
If the error persists after updating your payment method, your bank may be declining the charge on its end, or there could be an outstanding balance on your Apple ID account. Check with your bank to confirm there are no blocks on Apple charges. Also check for any past-due subscriptions in Settings > Your Name > Subscriptions, and clear any balance shown there.
Can a VPN cause SKErrorDomain-0?
Yes. A VPN can cause SKErrorDomain-0 if it routes your traffic through a server in a different country than the one your Apple ID is registered to. Apple's payment system checks regional consistency, and a mismatch can block transactions. Disable your VPN before attempting any App Store purchase, then re-enable it afterward if needed.
