Frequently asked questions
Everything you need to know about asms.ai.
What is a temporary / OTP phone number?+
A real phone number you use for a short time to receive an SMS verification code, without using your own SIM or revealing your personal number.
How fast do codes arrive?+
Usually within seconds. You watch for the code live on screen, there is nothing to install.
Are there free numbers?+
Yes. The free public numbers are shared, with a public inbox anyone can see, ideal for low-stakes verifications. For a number only you can see, use a paid private number.
Which countries and services are supported?+
Hundreds of services across the US, UK, Germany and more, with live availability shown before you buy.
What if no code arrives?+
On the paid tier, if a code does not arrive within the window your wallet is refunded automatically, so you only pay for codes you actually receive.
How do I pay?+
Top up a wallet with crypto, card or PayPal and pay per code. No subscriptions, no hidden fees.
Can AI agents use it?+
Yes. A clean REST API and a native MCP server let scripts and AI agents order numbers and read codes on their own.
Is it private?+
Your real number is never exposed. Free numbers are shared with a public inbox; private numbers are dedicated to your account only.
