Many beginners want to use GPT-4 but get stuck at the Plus subscription stage. This guide walks you through the full process of registering a ChatGPT account, upgrading your subscription, and switching between accounts — so you can quickly start using the more powerful AI model.
Step 1: Register Your Basic ChatGPT Account
Go to the OpenAI website and click “Sign Up” to create an account using your email or Google account. Note: If you're in a restricted region, you'll need a VPN with global proxy enabled to avoid blocks. After registering, verify your email to complete the basic account setup.
The free account gives you access to GPT-3.5. To unlock GPT-4, web browsing, image generation, and other features, you must upgrade to ChatGPT Plus.
Step 2: Add a Payment Method to Subscribe to Plus
After logging in, click “Upgrade to Plus” in the bottom-left corner and select the individual plan ($20/month). For payment, we recommend using an international credit card (e.g., a virtual card). Domestic Visa/Mastercard cards issued in some regions may occasionally be declined.
If you see “Your card has been declined,” try switching your IP address or binding Apple Pay/Google Pay to bypass risk control. Once the payment goes through, your Plus subscription is activated, and you can immediately use the GPT-4 model.
