Conclusion
Subscribing to ChatGPT from China follows one fixed three-stage money path, and both the success rate and the bill depend on whether all three stages line up: USDT into your account → the account funds the card → the card takes the subscription charge. If any stage isn't ready, it shows up as "subscription failed" — but the cause is completely different in each case.
The three-stage chain: how the money actually moves
Stage 1 · Account top-up
Top up your platform account with USDT. Account top-up is free, with a minimum of 20 USDT per transaction, supported only on the TRC20 and ERC20 chains — pick the wrong chain and the funds never arrive, and they are not automatically returned either.
Stage 2 · Card top-up
Move funds from your account balance onto the card at a flat 3% — this is the only tier. Card balance is a single one-time pool with no monthly reset, so size your funding to actual usage.
Stage 3 · Subscription charge
The platform charges the subscription fee to the card. This stage is directly tied to the card's balance, its status, and whether the card BIN supports AI subscription scenarios.
Three payment paths, distinguishable on the bill
| Path | Merchant name on the bill | Billing method | Unsubscribe / refund differences |
|---|---|---|---|
| Web subscription | Appears under a subscription-type merchant name | Charged on a monthly cycle | Manage the subscription on the platform side; refund eligibility for current-period charges depends on the purchase channel and applicable rules |
| In-app purchase (iOS / Android) | Appears under the Apple / Google store name | Charged at the store's listed price | Refunds go through the store's dispute process, unrelated to the platform |
| API top-up | Appears under the bare brand name | One-time prepaid, consumed by usage | This is a prepayment, with different rules from subscriptions |
The merchant name is the most direct clue for telling "which path you took"; the exact descriptor depends on what your own bill shows.
This table has two practical uses: first, figure out which path you took (look at the merchant name on your bill); second, find the right party when something goes wrong — for disputes over in-app purchases, platform support can't help; only the store can.
The listed price is not the billed amount
The listed price is exclusive of tax; the actual charge adds the checkout tax (rates vary by US state) plus, where applicable, exchange rates and cross-border surcharges. This part has nothing to do with "which card you use".
And "what you actually pay" has one more layer on top: the 3% card top-up fee. So when planning funds, estimate at listed price × 1.03 plus a little buffer, not at the listed price — insufficient card balance is one of the most common causes of failed subscription charges.
| Tier | Official listed price (monthly) | Recommended card balance |
|---|---|---|
| Entry tier (e.g., Plus) | $20 | ≥ $26 |
| High tier (e.g., Pro) | from $100 | ≥ $110 |
Budget based on the tax-inclusive amount with a buffer; refer to the pricing page and the card issuance page for the exact rates and minimums in effect.

Key actions for setup and card binding (not shown screen by screen here)
Where things actually fail is almost never "couldn't find the button" but an environment that doesn't line up. Binding the card only makes sense when four things hold at the same time:
- Account: an account that meets the service-region and eligibility requirements.
- Network: keep the network environment reasonably stable while in use and avoid frequent country / region switching; the platform doesn't recommend deliberately configuring a specific regional node.
- Billing address: copy the exact set assigned to you on the card details page (first line street only, second line blank, city / state / ZIP consistent).
- Card: the BIN description states it supports AI subscription scenarios, and the balance and available amount cover this charge.
The screen-by-screen operations (which page, which button, how to fill in the card details) are in the ChatGPT subscription illustrated tutorial;
After binding: renewals, invoices, unsubscribing
Renewals
Subscriptions are recurring charges; no one comes to ask you every month. If the card balance is insufficient around the renewal date, the result isn't "carried as arrears" — the subscription is interrupted. So keep a card balance buffer sized to the tax-inclusive amount.
Invoices and receipts
The subscription platform's billing page can usually provide proof of payment. For cross-border subscriptions the receipt is an electronic bill, not necessarily an invoice in the tax sense — confirm your organization's receipt requirements before asking for reimbursement.
Unsubscribing
Cancellations are handled on the subscription platform side. Refund eligibility for current-period charges depends on the purchase channel and applicable rules; your benefits last until the end of this billing cycle, and no further charge is made on the next billing date. If you just want to lower costs, downgrading is usually simpler than "cancel and resubscribe" — the latter means going through payment risk control again.
Refunds and balance recovery: two pools, two paths
Many people treat "unsubscribing" and "refunding" as one thing; they are actually two different pools:
| Pool | How it's handled | Key point |
|---|---|---|
| Card balance | Move it back to the account balance per the rules | The move back itself is free, but must come a certain time after the last card transaction (currently 48 hours) |
| Account balance | Returned to your USDT address per the refund process | Flat $3 per transaction; this is a prepayment refund, not a withdrawal, and the account is not closed because of it |
Suggested order: first unsubscribe (stop future charges), then move the card balance back to the account, and finally return USDT from the account as needed. Skipping steps tends to produce situations like "unsubscribed but the card still has money" or "the funds were moved back but next month's charge still went through". For details on the two paths, see Moving card balance back to the account and Withdrawing account balance.
Frequently asked questions
Can a domestic Chinese credit card subscribe to ChatGPT?
In practice, almost never. Even with a dual-currency card that has an international channel, the payment side's country-consistency check can't be passed — if the card's country, the IP's country and the billing address's country don't match, the request is blocked in the lead risk control before the card is even reached.
Why is my bill around $21 when I subscribed at $20?
The listed price is exclusive of tax; the checkout adds the tax back in. Rates vary by US state, so a difference of a dollar or two is normal. Go by what the checkout page shows, and keep a few extra dollars of buffer when funding.
How much does a card top-up cost?
Flat 3%, and it's the only tier; account top-up is free. The minimum top-up is 20 USDT per transaction, supported on TRC20 and ERC20 only.
Can I get back the money left on the card?
Yes. Card balance can be moved back to the account per the rules (free, needs 48 hours after the last card transaction); the account balance can then be returned as USDT via the refund process, at a flat $3 per transaction.
How long can I keep using the subscription after unsubscribing?
Refund eligibility for current-period charges depends on the purchase channel and applicable rules; benefits last until the end of this billing cycle, and no further charge is made on the next billing date.
Do subscription and API share the same balance?
No. Subscription and API top-up are two separate billing systems with different merchant names on the bill; buying a subscription doesn't turn into API balance.
Does card balance reset monthly?
No. Card balance is a one-time total pool; you top up again once it's used up. There is no monthly reset.
