Simscribe turns an Android phone into an SMS gateway you control via API. Pair it in seconds with a QR code, then send single or bulk messages with templates, track delivery in real time, and integrate via REST API + signed webhooks. No carrier-grade fees — just the SIM plan you already have. Built for indie hackers, small teams, and anyone sending SMS notifications or alerts who wants a cheaper alternative to Twilio. Free plan, no credit card required.
