KYROSMS Mobile Gateway Application

KYROSMS Mobile Gateway Application

Real-time mobile SMS gateway built with React Native (Expo), enabling smartphones to function as event-driven SIM bridges for SMS broadcasting and teleconferencing.

Overview

A cross-platform mobile gateway that transforms Android smartphones into low-latency communication hubs. The application maintains persistent WebSocket connections to receive real-time messaging requests, executes SMS transmissions through the device's native SIM hardware, stores immutable audit logs in SQLite, and supports programmatic teleconferencing.

Key Contributions

  • Developed the mobile gateway using React Native and Expo.
  • Implemented persistent full-duplex WebSocket communication for real-time message streaming.
  • Built a local SQLite audit system for transmission history and delivery tracking.
  • Integrated native Android SMS capabilities to automate SIM-based message delivery.
  • Implemented automatic reconnection logic to recover from network interruptions.
  • Developed a live monitoring dashboard for connection health, throughput, and transmission status.
  • Designed the architecture supporting teleconferencing workflows through native cellular services.

Challenges

Building a low-latency event-driven communication pipeline that reliably executes hardware-level SMS operations while maintaining persistent WebSocket connectivity, fault-tolerant reconnection, and consistent local audit logging under unstable mobile network conditions.

Outcome

Delivered a production-ready mobile gateway capable of processing real-time messaging requests through native SIM hardware, providing reliable audit trails, resilient network recovery, and scalable communication infrastructure without relying on third-party SMS providers.
