Smart Channel Fallback
Maximizes delivery by attempting cheaper routes (WhatsApp) first, then falling back to SMS or Voice instantly if undelivered.
Global Reach

Silent Verification
Verify phone numbers without user interaction using SIM-based network authentication (Header Enrichment).
Managed Logic
We handle code generation, storage, expiry, and retry logic. You just call "Verify" and "Check".
Fraud Detection
