1. Executive System Overview & Purpose

SimRelay Android SMS Bridge is an innovative hardware-free GSM SMS gateway server that transforms standard Android smartphones into low-cost, high-volume SMS dispatch servers. Designed for cost-conscious startups, local alert services, and regional businesses, it bypasses expensive cloud SMS aggregator fees by utilizing local cellular mobile plans.

Featuring multi-SIM card rotation across connected Android devices to bypass carrier rate limits, a clean RESTful API for programmatically sending and receiving SMS, incoming message webhook callbacks, and battery status health monitoring, CellRoute delivers an economical SMS infrastructure.
