worth knowing.
Still have a question?
We’re here to help
When can I use MobiMatter in ChatGPT?
The integration is coming soon. This page gives you a preview of the experience. Availability and supported ChatGPT experiences will be confirmed at launch. You can already browse and buy eSIMs on MobiMatter.
Do I need to connect my MobiMatter account?
Not to find and compare plans. Account connection is optional and is only needed when you want to see your own eSIMs, remaining data and validity.
Can I buy an eSIM inside ChatGPT?
You can compare plans in the conversation. When you choose one, you’ll open its product page on MobiMatter to review the details and complete your purchase.
What can ChatGPT see when I connect my account?
The integration provides read-only access to your eSIM plans, providers, saved labels and usage information. Saved labels are shared as you wrote them and may contain personal information. The tools do not expose your profile, payment details or eSIM activation secrets.
Are prices, coverage and usage always up to date?
Recommendations use the current MobiMatter catalog. Always review the final price, coverage and plan terms on the product page before buying. Network access does not guarantee reception everywhere, and providers may report usage with a delay.
