An SMS OTP alternative is any phone-ownership check that does not send a one-time code. For Egypt and MENA apps, missed-call verification is the practical alternative: the user proves they control the SIM by placing a brief unanswered call.
SMS OTP vs missed call
| Topic | SMS OTP | Missed call |
|---|---|---|
| User action | Wait, copy, type a code | Place a short call |
| Failure mode | Message delayed or blocked | Call cannot be placed |
| Cost shape | Pays even when the user abandons | Credits for completed verification |
| Spam folders | Yes | No code to lose |
Why teams in MENA look for an OTP alternative
Messaging rates add up. Deliverability is uneven across operators. Users on prepaid plans may receive OTP late or not at all. Product teams then add “resend code” buttons that still do not fix the route.
How Shernova fits
Shernova is phone verification as a service for developers: REST API, Flutter SDK, and signed webhooks. You keep your own login, users, and database. Shernova confirms that the submitted mobile number can place the missed call for that session.
See the migration guide if you already send SMS OTP today.
Next step for developers
Shernova is a phone-verification layer for your app, not an end-user consumer app. Create a developer account, follow the quick start, then test the flow from the dashboard.
