FAQ: virtual numbers for SMS OTP

How do I receive SMS verification codes online?
Open SMS Duo, pick an app and country, buy a virtual number, enter it in the app, then read the OTP in the dashboard.
Is it free, and is delivery guaranteed?
Only the shared numbers in our free public inbox are free (anyone can read those messages and many apps reject them). The private numbers on this page are paid per use. Delivery is not guaranteed: delivery rates depend on upstream carriers and app risk controls.
Do I need a physical SIM?
No. Numbers are virtual sessions inside the web app.
Can I reuse the same number?
Usually each purchase is one session. Buy again when you need another verification.
