Use case

OTP delivery that actually arrives.

Send one-time codes from your own SIM. No short-code filtering, no A2P registration, no per-code fee.

Why teams switch

  • Codes were arriving late — or not at all. Aggregator short codes get filtered; a 30-second delay on a 5-minute OTP is lost users.
  • Per-message billing on auth traffic adds up fast.
  • Registration slowed launch. A2P 10DLC vetting before you can even send.

How SMSKit fits

Real local number, carrier-trusted, typically delivered within seconds (carrier-dependent). Priority routing pushes OTPs ahead of bulk. Idempotency keys mean a retried request never sends two codes.
