This tutorial will guide you on how to top up your MPCard through the MPChat app and successfully pay for an OpenAI ChatGPT Plus membership.
✅ Preparation
An OpenAI Account: Ensure your account is successfully registered and can log in to ChatGPT normally.
A suitable email: Register with Gmail or another overseas mailbox. Avoid QQ / 163 / Sina / company email addresses — they are more likely to trip platform risk controls.
Stable Network Environment: Crucial! Please use a clean IP from a region supported by OpenAI (e.g., USA, Japan, UK) and complete the entire payment process under this environment.
MPChat App: Please download the latest version from the official app stores:
Or visit the official website: mp.net
USDT Assets: Used to top up your MPChat wallet.
Tip: The monthly fee for ChatGPT Plus is $20. It is recommended to prepare at least 25 USDT (equivalent) to cover exchange rate fluctuations and small verification holds.
🛠️ Step-by-Step Instructions
Step 1: Top up USDT to Pay
Open the MPChat app, go to the Asset page, and open Pay.
Click "Deposit." The system will generate a dedicated USDT deposit address (ensure the network matches the address type, e.g., ERC20).
Transfer sufficient USDT from your external wallet or exchange to this address (recommend at least 25 USDT equivalent).
Wait for the network to confirm the deposit.
Step 2: Apply for and Fund your MPCard
Enter the "MPCard" section within MPChat.
Click "Apply for New Card." A virtual card will be generated instantly. MPChat cards are issued in Singapore and settle in USD — they are not US-issued cards. For billing, enter a real address whose country matches your exit IP — the App does not provide a billing address.
Once the card is generated, find the "Transfer" function on the "Wallet" or "MPCard" page.
Transfer USDT from your Pay assets to your "MPCard" assets, ensuring the card balance exceeds $20.
Step 3: Bind Payment Method on the OpenAI Page
Under a stable network environment, visit ChatGPT and log in.
Click on your personal account in the bottom left corner, go to "My plan," and select "Upgrade to Plus."
On the payment interface, click "Add payment method" and accurately fill in your MPCard information:
Card number: Your 16-digit MPCard number.Expiration date: Expiry date.CVC: Security code.Name on card: Use your real name (Latin letters).
Billing Address (The key to success!): Enter a real, valid-format address whose country/region matches your current exit IP (street, city, state, ZIP). The MPChat App does not provide a billing address — you find and fill one yourself. A randomly invented address often fails merchant checks. A US-format address with a US exit IP is for AVS matching; it does not mean the card is US-issued.
Step 4: Complete Subscription
After filling in all information, click subscribe. The system may perform a $1 small verification hold (which will be refunded). Once verified, $20 will be deducted, and the subscription is successful.
If the merchant triggers 3DS / Visa Secure, a one-time code is sent to both your MPChat registered email and the MPChat App notification inbox. Enter the code once to finish payment. You only need one of the two channels.
✅ Congratulations!
Your ChatGPT Plus membership is now active. Enjoy your powerful AI assistant!
❓ Frequently Asked Questions (FAQ)
Q1: What is the most common reason for payment failure?
The "Mismatch Trio": Your exit IP region, account region, and billing-address country should match. 99% of failures stem from this. MPChat cards are Singapore-issued and settle in USD — they are not US-issued cards. Enter a real billing address that matches your exit IP; the App does not provide a billing address.
Invalid Address: Use a real address that matches your exit IP region (street, city, state, ZIP). The MPChat App does not provide a billing address. Randomly invented addresses often fail merchant checks.
IP Issues: The IP is blacklisted or of poor quality. It is recommended to switch to a clean residential IP.
Q2: The deduction was successful, but the subscription is not activated. What should I do? This is usually due to network latency or OpenAI system issues. Please DO NOT repeat the subscription immediately. It usually activates within a few minutes. If it is not active after 1 hour, please save your payment voucher and contact OpenAI official customer support.
Q3: How do I cancel the subscription? ChatGPT Plus is a monthly service and can be cancelled at any time. Click your account in the bottom left of the ChatGPT page, go to "My plan" → "Manage my subscription" to cancel auto-renewal. Your benefits will continue until the end of the current billing cycle.
Q: If my AI account is banned, will it affect my card? Yes, it can. After a platform bans an account, cards bound to that account are often flagged. Binding the same card to a new account can cause the new account to be restricted as well. Use one card per AI account, and do not reuse a card that was tied to a banned account.
Q: What should I watch for during sign-up / email verification? Keep the same exit IP from registration through email verification. When you click the verification link or enter the code, the IP must match the one used to register. Switching IPs at that moment is a common reason accounts get flagged. Use a stable, clean exit IP for the target region; MPChat does not sell or recommend any specific VPN or proxy product — choose a lawful, stable option yourself.
Q: Where does the 3DS / Visa Secure code go? To both your MPChat registered email and the MPChat App notification inbox. Enter the code once to finish payment. If it does not arrive, see Can I set up 3DS security authentication for payments?.
💡 Summary and Tips
Key to Success: A stable local IP and a real, matching billing address are the keys to a successful subscription.
