• Account Management: Create multiple accounts for different purposes (personal, business, testing)

• Convenience: Instant access without waiting for carrier-specific delays

Preparation

Use an IP Address from a Supported Country

You must use an IP address from a country that is supported by OpenAI ChatGPT. As of 2025, OpenAI has expanded availability to over 160 countries and territories, but some restrictions still apply.

Step 4 – Sign Up for OpenAI ChatGPT

Once you have acquired a temporary phone number from the previous step, you can now proceed to sign up for an account on OpenAI ChatGPT.

Step-by-Step Registration Process:

1. Go to chat.openai.com
2. Click “Sign up” to create a new account
3. Enter your email address (use a valid email you can access)
4. Create a secure password
5. Verify your email address when prompted
6. Enter the temporary phone number from MobileSMS.io
7. Wait for the SMS verification code (usually arrives within 1-3 minutes)

The SMS Verification Code for OpenAI ChatGPT will be sent to the temporary phone number and displayed for you to see in your MobileSMS.io dashboard.

Pro Tips for Successful Verification

Follow these expert recommendations to ensure smooth account creation:

Timing is Everything

• Complete the registration process immediately after getting your number
• Don’t let your temporary number sit unused for more than 5 minutes

Best Practices for 2025

• Use a clean browser session: Clear cookies or use incognito/private browsing mode
