GotSMS vs. Free public OTP sites
Only usable for demoing what NOT to do. Never use a public number for anything you actually care about.
GotSMS
- Every line is a dedicated physical carrier connection, never shared
- Self-service Refund button — no support ticket, available for 24 hours after purchase if no SMS arrives
- Full REST API for CI/CD and automation workflows
From $1.00/day, tiered rentals up to 1 year
Free public OTP sites
- Zero cost
- No signup required
- Codes are visible to every visitor on the page simultaneously
- Numbers are blacklisted by every major platform almost immediately
- Zero privacy, zero reliability, zero support
Free, but functionally unusable for anything but throwaway testing
