Before you pay
Check your chosen card’s balance in AnyPay. Move money from the wallet to the card if needed: merchants charge the card balance.
Pay with Ultimate
These are the payment methods available with Ultimate. Choose one suitable option.
Option 1 — on the official website
Pay for ChatGPT using your Ultimate details. Copy the billing address from this card’s details in AnyPay.
- Sign in to the intended account at chatgpt.com. Open the profile menu → Upgrade plan and choose a plan.
- Choose card payment. Open Ultimate in AnyPay and enter its number, expiry date and CVV/CVC. Use your real name in Latin letters and the billing address from the card details (Singapore).
- Check the total and confirm the purchase. If prompted for 3D Secure, complete it in AnyPay and return to the merchant.
- Wait for confirmation and check the purchase or subscription in the intended account. Do not repeat a payment while it is processing.
Option 2 — through the App Store on iPhone
Apple bills the purchase through the official ChatGPT app. Add the card to your Apple Account payment methods; adding it to Wallet is a separate step.
- Add Ultimate to an Apple Account with region Singapore using the guide below. Before changing regions, check Apple’s requirements for existing subscriptions and account balance.
- Install the official ChatGPT app by OpenAI. Sign in to the intended account → Settings → Upgrade and choose Plus or another available in-app plan. Use the website to upgrade from Free to Pro.
- If Apple’s purchase sheet appears, review the plan, billing period and total, then confirm. A redirect to a website is a website payment, not an App Store purchase.
- Check activation in the same ChatGPT account. Manage renewal and cancellation of Apple-billed purchases in Settings → your name → Subscriptions.
