Signal requires a phone number to register. Buy a virtual number on SMS Duo and receive the Signal SMS verification code online — useful when you want a session line instead of your personal SIM for every check.
SMS Duo is unaffiliated with Signal. Delivery is not guaranteed; some ranges may be blocked.

Signal registration is phone-number based. If you prefer not to bind your primary mobile for every new install or recovery flow, a pay-per-use virtual number lets you submit a session line and read the OTP in the SMS Duo dashboard.
Success is not guaranteed on every attempt. Signal may reject some virtual ranges. When that happens, try another country with available stock instead of expecting 100% delivery or free codes — we do not offer either claim.
Use verification only for legitimate account access and follow Signal's terms. SMS Duo provides the SMS receive layer only and is not affiliated with Signal Messenger LLC.
