SMS verification infrastructure built for global scale
AtlasSIM connects millions of users to reliable virtual numbers in 180 countries, verifying any service within seconds.
From an idea to the reference platform
AtlasSIM was born in 2021 from a simple observation: receiving a verification code by SMS from a reliable number remained complicated, expensive, or insecure for millions of developers, testers, and digital marketing professionals.
Our founding team, coming from telecoms and software engineering, built a first version connected to a handful of operators in 12 countries. Demand exploded within months, driven by the developer and QA communities.
Between 2022 and 2024, we multiplied carrier partnerships, launched a public API, and industrialized our SMS routing infrastructure to guarantee near-permanent availability.
Today, AtlasSIM serves more than 180 countries and 1,500 services, with a user base that keeps growing every month, from independent developers to technical teams at technology companies.
