Google Voice is not available everywhere and is not designed as a disposable OTP shop. SMS Duo offers session-based virtual numbers when you need to receive Google (and other) SMS codes online.
Comparison phrasing only — we are not affiliated with Google. Use SMS Duo when you need pay-per-use verification tooling.

Google Voice can be a great personal number product in supported regions, but many users simply need a one-time SMS for Google account recovery, Gmail-related checks, or other services that ask for a code. A dedicated Voice line is overkill for that workflow.
SMS Duo is a different product category: buy a virtual number session, receive the SMS in your dashboard, and move on. Stock spans multiple countries when available. We do not claim to replace every Voice feature (calling, voicemail, long-term number porting).
If your goal is Google OTP specifically, also see our Google SMS guide. Always follow Google policies; automated abuse is not supported.
