To subscribe to ChatGPT Plus, log in to your OpenAI account, navigate to the sidebar, and click “Upgrade Plan” to select the standard $20/month tier. Users can complete the purchase using a credit card on the web interface or utilize Apple Pay and Google Play billing through the official iOS and Android apps to bypass potential regional payment restrictions.
However, the new $200/month ChatGPT Pro tier complicates matters, leaving standard users frustrated by strict usage caps and locked out of advanced tools like Sora 2 Pro.
GlobalGPT solves this fragmentation by aggregating over 100 top-tier AI models—including GPT-5.2, Claude 4.5, and Sora 2 Pro—into a single platform that costs significantly less than a standard Plus subscription.

How to Subscribe to ChatGPT Plus? (Web & Mobile Guide)
Subscribing to ChatGPT Plus is relatively straightforward, but choosing the right platform (Web vs. App) can determine whether your payment succeeds or fails. OpenAI currently supports direct payments via Stripe for web users and integrated store billing for mobile users.
Method 1: Upgrading via OpenAI Official Website
- Log in and Locate Upgrade: Navigate to
chatgpt.com, log in, and click on your profile name in the sidebar. Select “Upgrade Plan” from the menu.

- Select the Tier: You will see the standard Plus plan ($20/month) alongside the new Pro/Team options. Select “Upgrade to Plus.”

- Complete Checkout: Enter your credit card details. Note that OpenAI strictly verifies that your card’s billing address matches your current IP region.
Method 2: Subscribing via iOS/Android App (Recommended for International Users)
- Download the Official App: Ensure you have the genuine OpenAI ChatGPT app from the App Store or Google Play Store.
- Use Apple Pay / Google Play: Go to Settings > Upgrade to ChatGPT Pro > Get Pro. This method often bypasses the strict “credit card declined” errors common on the web version because the payment is processed by Apple or Google, not Stripe directly.

- Manage Easily: Subscriptions made here must be cancelled through your phone’s subscription settings, not the web dashboard.
Why Was Your Credit Card Declined When Subscribing?
“Your card has been declined” is the most common error message users face when attempting to upgrade. OpenAI uses a highly sensitive fraud detection system (powered by Stripe) that flags transactions for minor discrepancies.
Common Triggers for Payment Failures:
- Prepaid and Virtual Cards: Most prepaid cards (e.g., Vanilla Visa) and some virtual banking cards (like early Revolut or Wise batches) are automatically blocked to prevent fraud.
- IP Address Mismatch: If you are using a VPN to access ChatGPT from a supported country but your credit card is issued in a different region, the transaction will be flagged as “High Risk.”
- Browser Caching Issues: Sometimes, residual browser cookies trigger false security flags. Clearing your cache or using Incognito mode can occasionally resolve the “Upgrade button not working” glitch.
Pro Tip: If you consistently face these blocks, switching to an AI aggregator like GlobalGPT can bypass these payment friction points entirely, as they support a wider range of global payment methods without strict region locking.
Is the $20 ChatGPT Plus Subscription Actually Enough in 2025?
While the $20/month Plus plan was once the gold standard, the introduction of the $200/month ChatGPT Pro tier has significantly devalued the standard offering. Users are often surprised to find that “Plus” no longer grants access to OpenAI’s most powerful capabilities.
The “New Tier Trap” & Hidden Limitations:
- Gatekept Models: The most advanced reasoning models (like the full unquantized OpenAI o3-proor GPT-5.2 Pro) are increasingly reserved for the $200 Pro tier, leaving Plus users with “distilled” or slower versions.
- Sora 2 Restrictions: Standard Plus users facing strict generation limits. To get Sora 2 Pro features—such as 25-second video generation and watermark-free downloads—you are often pushed toward the expensive Pro subscription.
- Usage Caps: Plus users are still subject to message caps (e.g., 40 messages every 3 hours) during peak times. This means heavy workflows can be interrupted abruptly, forcing you to wait or switch to inferior models.

Can You Get GPT-5.1 & Sora 2 Pro Without Paying $200?
For most users, paying $200 per month for a single platform is financially impractical. This price shock has led to the rise of “All-in-One” AI platforms that aggregate top-tier models for a fraction of the cost.
The GlobalGPT Advantage:
- Sora 2 Pro Integration: Unlike the standard ChatGPT Plus plan, platforms like GlobalGPT integrate Sora 2 Pro directly, allowing users to generate longer videos (up to 25 seconds) without watermarks or waitlists.
- Cost Efficiency: Instead of paying $200 for official Pro, users can access the same high-end models (including GPT-5.1 and Claude 4.5) starting at approximately $5.75.
- No “Ecosystem Lock”: You are not restricted to OpenAI’s ecosystem. You can switch from GPT-5.2 to Google Gemini 3 or Claude 3.5 Sonnet in the same chat window, ensuring you always use the best model for the task at hand.

Which Subscription Should You Choose? (Detailed Comparison)
Choosing between the official direct subscription and an aggregated platform depends on your specific workflow needs and budget.
Scenario A: The Casual Mobile User
- Recommendation:Official ChatGPT Plus ($20).
- Why: If you primarily use Voice Mode on your iPhone while driving or need the history sync feature heavily on the official mobile app, the $20 official plan is a solid, albeit limited, choice.
Scenario B: The Power User & Content Creator
- Recommendation:GlobalGPT (~$5.75).
- Why: If you need Sora 2 for video creation, require access to Claude 4.5 for coding, or simply refuse to pay $200 for “Pro” features, an aggregator offers superior value. You get watermark-free video generation and access to 100+ models without usage caps.
