# Are there restrictions when using the Sandbox Account?

Yes, the Sandbox Account is limited to testing purposes. You can only send SMS to your registered mobile number (auto-whitelisted) using the default sender ID and provided templates. This keeps it safe and controlled. To test more numbers, whitelist them via the dashboard. It’s not for live campaigns—upgrade to a paid plan for full flexibility.
