Introduction
If you’ve tried signing up for ChatGPT, you already know the frustration: you can’t get past phone verification without giving up your real number. For privacy-conscious users, students, and freelancers, this feels like a trap. MobileSMS.io, trusted since 2018, offers a safe way to use ChatGPT without phone number exposure.
This guide will explain why ChatGPT blocks many numbers, how to bypass this problem securely, and the exact steps to set up ChatGPT with MobileSMS.io. You’ll also see pricing comparisons and why long-term rentals are the best fit for most users.
Problems with Phone Verification
ChatGPT requires SMS verification to reduce spam and fraud. But for real users, this process creates three major pain points:
- Rejected VoIP numbers: Many people try free apps like Google Voice or TextNow. These are almost always blocked by OpenAI.
- Privacy risks: Using your personal number ties your identity to your ChatGPT account. This risks spam, tracking, and potential leaks.
- Limited global access: Some users outside the USA or Europe can’t verify at all because local numbers aren’t accepted.
Example: A student in India might try using a local virtual number, only to see ChatGPT reject it. Or a freelancer managing multiple accounts may get flagged for “suspicious activity” because the same number was reused.
These challenges make a reliable, privacy-first solution essential.
MobileSMS.io Solution
MobileSMS.io was founded in 2018 to solve exactly this problem. It provides real SIM-card-based numbers that work where VoIP fails.
Key Differentiators
- Non-VoIP Numbers – Accepted by ChatGPT, unlike free VoIP services.
- Flexibility and Privacy – Options for one-time use or long-term rentals.
- Global Reach with USA Specialization – 100+ countries supported, but USA numbers are most available.

Here’s a quick look at the main options:
| Service Type | Duration | Price (USA) | Best Use Case |
