Why Choose Claude Sonnet 3.5?#
The Claude series models are developed by the Anthropic team, and compared to other AI models, it stands out in safety, contextual understanding, and multilingual support. Sonnet 3.5, as the latest version in 2025, further optimizes performance, capable of handling complex programming tasks and generating text that aligns more closely with human language habits. For domestic users, whether for academic research, content creation, or enterprise-level applications, Claude can provide strong support. However, the process of subscribing to Claude Plus or recharging the API often deters many people—issues like overseas credit card payments and network restrictions are common. At this point, WildCard becomes the "key" to unlocking this service.
WildCard: A Subscription Tool Tailored for Domestic Users#
Among numerous virtual credit cards or payment tools, WildCard is undoubtedly the best choice tailored for domestic users. Compared to tools like Dupay, VCard, PokePay, WasabiCard, or LocalCard that require cumbersome USDT recharges, WildCard's advantages lie in its simplicity and stability. It supports domestic payment methods like Alipay and WeChat, eliminating the need for additional cryptocurrency exchanges, and can be directly used for subscribing to Claude Plus or recharging the Anthropic API after recharging. More importantly, WildCard's service has been optimized over a long period, with a high success rate for payments, and almost no occurrence of the common "card declined" issue.

Complete Steps to Subscribe to Claude Plus#
To unlock all the features of Claude Sonnet 3.5, subscribing to Claude Plus is the most direct way. Below, we will guide you through the entire process step by step.
1. Register a WildCard Account#
First, open WildCard Official Website and click the "Register" button in the upper right corner. Enter your phone number (default +86 for mainland users, +852 for Hong Kong users), obtain a verification code, and submit it to complete the registration. Don't forget to enter the invitation code "LEIXUE" during registration to enjoy the card opening fee waiver. After registration, log in to your account, and you will enter a clear and concise management backend.
2. Open Card and Recharge#
In the WildCard backend, click the "My Cards" menu on the left, select the card opening duration (1 year for $11.99 or 2 years for $16.99, with a better deal using the invitation code). After confirmation, click "Pay" and complete the payment via Alipay or WeChat scan code. After successful card opening, the system will automatically generate a virtual card number, including the card number, expiration date, and CVV code. Then, go to the "Recharge" page and use Alipay or WeChat to recharge the card. It is recommended to recharge $25 for the first time, as there may be a $5 pre-authorization fee when binding payment, to avoid insufficient balance leading to subscription failure.
3. Visit the Claude Website and Subscribe#
Open the Claude website (https://www.anthropic.com), log in or register an account. On the subscription page, select Claude Plus (approximately $20 per month), and when filling in payment information, enter the virtual card number provided by WildCard. After submission, payment usually completes within seconds. If you encounter network issues, you can try switching to a stable overseas node or directly using the home network IP environment provided by WildCard to ensure smooth payment.
4. Verification and Use#
After successful payment, your Claude account will automatically upgrade to the Plus version. At this point, you can directly experience the powerful features of the Sonnet 3.5 model, such as a longer context window, faster response speed, and higher daily usage limits. If API access is needed, you can bind the same WildCard card in account settings for recharging.
Tips for Recharging Anthropic API#
In addition to subscribing to Claude Plus, many developers prefer to call the Sonnet 3.5 model through the API for automation tasks or integration into their applications. WildCard also supports API recharging, with steps similar to subscribing:
- On the API management page of the Anthropic website, add a payment method and enter the WildCard card number.
- Set the recharge amount (minimum $5) and confirm payment.
- After successful recharge, the API key can be used normally, and the cost of calling Sonnet 3.5 will be deducted from the card balance.
It is worth mentioning that WildCard does not charge cancellation fees, and only has a small fee for refunds or non-USD transactions (2% for refunds, 1% + $0.5 for non-USD transactions), making it highly cost-effective.
Comparison of WildCard with Other Tools#
There are some alternative tools on the market, such as Dupay, VCard, and PokePay, which mainly target cryptocurrency users and require recharging through USDT and other means, suitable for users with crypto assets. However, for ordinary users, this method is not only cumbersome but may also increase costs due to exchange rate fluctuations. The stability of WasabiCard and LocalCard is often questioned, and payment failures are not uncommon.
In contrast, WildCard's Alipay/WeChat recharge method is more in line with the habits of domestic users, with low thresholds for card opening and recharging (minimum $5), and no KYC certification is required for use (uncertified monthly limit of $100, increased to $3000 after certification). This makes it the preferred tool for domestic users to subscribe to Claude in 2025.
Notes and Common Questions#
- Network Environment: If payment is intercepted, it may be because the IP is recognized as a high-risk node. Switching to a less crowded proxy node or using a home network IP can resolve the issue.
- Insufficient Balance: When subscribing to Claude Plus, ensure that the card balance is greater than $20 + $5 (pre-authorization fee) to avoid failure.
- Service Support: WildCard provides real-time customer support. If you encounter problems, you can contact them through the official website, and response speed is fast.
