To activate the premium membership (ChatGPT Plus) for ChatGPT 5.2, you need to complete the following steps:

Register a ChatGPT account: Visit the official ChatGPT website and use your email to register an account.

Prepare a credit card that supports international payments: Since domestic credit cards may not be able to pay directly, it is recommended to use a virtual credit card service, such as WildCard or Depay.

WildCard: This is a convenient virtual credit card service that supports WeChat and Alipay payments, suitable for subscribing to overseas platforms like ChatGPT Plus. You can register and apply for a virtual credit card through the WildCard official website.

Depay: Depay is a US-based virtual credit card company, suitable for topping up ChatGPT Plus. You need to register a Depay account, download its app, complete identity verification, and then apply for a virtual credit card.

Top up the virtual credit card: Purchase USDT (Tether) and deposit it into your virtual credit card. You can use exchanges like OKX to buy USDT, then withdraw it to your virtual credit card account.

Upgrade to ChatGPT Plus: Log in to your ChatGPT account, click the "Upgrade to Plus" button in the bottom left corner, and select "Upgrade plan." On the payment page, fill in your virtual credit card information to complete the subscription.

Please note that ChatGPT Plus is a monthly subscription, costing $20 per month. If you do not wish to renew, you can cancel the auto-renewal; otherwise, the system will automatically deduct the fee.

Subscribing via Apple ID is currently very difficult to succeed. Using a Turkish ID is generally cheaper, but Apple's risk control is quite strict, and it relies entirely on luck.
