Use case

OTP delivery that actually arrives.

Send one-time codes from your own SIM under your carrier's normal terms. No SMSKit 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.
  • Carrier registration slowed launch. Approval took time before you could even send.

How SMSKit fits

Real local number, typically delivered within seconds (carrier-dependent). Priority routing pushes OTPs ahead of bulk. Reuse an idempotency key when you retry a request and the API returns the original job instead of queuing a second code (while that job is retained). Delivery retries can still duplicate an SMS.
