Step 4: Complete Subscription
After filling in all information, click to confirm the subscription. The system will perform a small verification hold (which will be refunded). Once verified, $20 will be deducted, and the subscription is successful.
❓ Frequently Asked Questions (FAQ)
Q1: What is the most common reason for payment being declined?
The "Mismatch Trio": Your network IP location (must be USA), the MPCard issuing country (must be USA), and the country of the billing address (must be USA) must be 100% identical.
IP Quality Issues: Using data center IPs or flagged IPs is highly likely to fail. It is strongly recommended to use a clean U.S. residential IP.
Invalid Address: Randomly written addresses cannot pass risk control; you must use a real address generator that passes basic verification.
Q2: Can I log in and use Claude Pro from anywhere after subscribing? Yes, but it is recommended to maintain consistency in your login environment. Once subscribed, Claude Pro benefits are bound to your account. However, frequently switching login IPs between different countries may pose potential risks. Try to keep the network environment stable during daily use.
Q3: How do I cancel the subscription? Claude Pro is a monthly service and can be cancelled at any time. Click your account email in the left sidebar of the Claude web page and go to "Manage your plan" to find the cancellation option. Your benefits will continue until the end of the current billing cycle.
Q4: How does Claude's risk control differ from OpenAI's? Based on user experience, Anthropic's (Claude) payment risk control system may be stricter, requiring higher IP purity and billing address authenticity. If it fails once, prioritize switching to a higher-quality IP address.
💡 Summary and Tips
