SMS
A text to their phone. Price can vary by country.
OTP verification
Send a code. Verify what they type.
Seamtel sends a one-time code over SMS, WhatsApp, or email. The user reads it. You
verify what they type. You never see the digits. You hold a
reference.
Login, signup, and transaction confirmation. Not a broadcast channel. Not marketing.
Channels
Three inboxes. One loop.
Pick a channel per send. The code, the expiry, and the verify step stay the same.
Same 6 digits, different inbox. If they live in WhatsApp, send them there.
Same code, to an inbox. One price, everywhere.
How it works
Ask. They read. You confirm.
01
You send
Your app asks Seamtel to deliver a code. You get a reference back, not the digits.
02
They read it
The code lands on their phone or in their inbox. They type it into your app.
03
You verify
Pair the reference with what they typed. We say yes or no. Guessing the code is free.
Disposable numbers
Rent a number to receive the code
Some sign-ups only accept a phone number. Rent a disposable one and the message arrives on this screen, so you never hand over your own.
Checking is automatic while the order is open, and the countdown shows how long the number stays live.
