Frequently asked

What is Seamtel?
Seamtel is a messaging platform for businesses and developers. Use our APIs to send SMS, deliver verification codes, and keep customers informed across SMS, WhatsApp, and email. We also offer virtual phone numbers for receiving SMS and verification codes online. Access our services through your dashboard or integrate them into your application using our REST API.
Is there an API?
Yes. Every account can mint a bearer API key and call the same catalog the dashboard uses: providers, countries, services, pricing, orders, and OTP send and verify. The endpoints are documented at /documentation, with a full API reference alongside.
Can I use this inside my own product?
That is what the API is for. Send verification codes from your own signup or login flow, order numbers programmatically, and track everything against your wallet. Keys carry their own rate limits, so one busy integration cannot starve the rest of your account.
Do I need to write code to use it?
No. The dashboard does everything the API does: order a number, read the code, send a verification, manage keys. If you never touch the API, nothing is missing.
Which countries can I get numbers from?
Over 50 countries, including the United Kingdom, United States, India, South Africa, Canada, Ghana, Bangladesh, Germany and France. Verification codes go further still. Email reaches anywhere.
How do I fund my wallet?
Open Deposit in your dashboard, enter an amount, and pay with a card, PayPal, bank transfer or cryptocurrency. Your USD balance updates automatically once the payment is confirmed.
What are credits?
Credits are prepaid bundles you buy once and spend on numbers. Each number costs a set amount of credits based on its price, shown before you confirm. No monthly cap and no price ceiling. Unused credits expire at the end of your subscription period.
What if a number does not receive a code?
If a number never receives a code, you are automatically refunded. We sit in front of multiple provider networks precisely so success rates stay high across the services you care about.

Your next number is
one account away.

Create an account, fund a wallet, and order your first number. Or skip the clicking and wire it into your product with a key.

Good conversations start with a hello.
