How It Works

OTP Delivery That Nigerian Fintech Trusts

When a user triggers an OTP request in your application, NigeriaSMS receives the API call, immediately routes the message through our direct MTN or Airtel connection based on the recipient's network, and delivers the OTP in under 3 seconds.

If primary delivery fails, our retry engine automatically attempts delivery through alternative network routes. If all SMS routes fail, the system can automatically initiate a Voice OTP call as final fallback — ensuring your users always receive their verification code.
