Android SMS Gateway is a lightweight Android application that turns a smartphone into an SMS gateway for sending and receiving messages through an API.
The tool solves the problem of integrating SMS functionality into applications without relying on third-party SMS services. It works by running on an Android device and exposing an API endpoint that allows programmatic sending of SMS messages and receiving of incoming messages via webhooks. Users can access the API directly on the device or route it through a cloud server when direct device access is not feasible. The application requires no registration in local mode, making it straightforward to deploy for personal or internal use.
The tool suits developers building applications that need SMS integration but want to avoid commercial SMS gateway costs or dependencies. It works well for small-scale deployments, testing environments, or scenarios where you control the Android device infrastructure. The project is compatible with Android 5.0 and later versions. The README does not name alternative projects for comparison.
Development activity shows consistent engagement with bug reports and feature requests being tracked through the issue system. The project maintains documentation through a dedicated docs site, indicating attention to user onboarding and API clarity. Build variants are offered to support different deployment scenarios, suggesting the maintainers have refined the tool based on real-world usage patterns.
