How It Works

Three simple steps to start sending SMS through your own devices.

Connect Your API

Generate your API key from the web dashboard. Integrate our REST API into your app with a few lines of code — we provide SDKs and full documentation.

Install the App

Download the Android app on any phone or tablet. Pair it with your account in seconds — the device registers automatically and starts listening for jobs.

Send at Scale

Submit messages via API or dashboard. Your devices send SMS through their own SIM cards with real-time delivery tracking and automatic retry on failure.

Multi-Device Fleet Management

Manage dozens of Android devices from a single dashboard. Monitor battery levels, signal strength, and carrier status in real time. Automatic load balancing distributes messages across your fleet for maximum throughput.

REST API + Web Dashboard

A full-featured REST API with webhooks, batch messaging, and scheduled delivery. Prefer a visual interface? The web dashboard lets you compose, send, and track messages without writing a single line of code.

Real-Time Delivery Tracking

Know exactly when each message is sent, delivered, or failed. Detailed analytics show delivery rates, response times, and per-device performance. Webhooks notify your app the instant a status changes.

Enterprise-Grade Security

JWT authentication with RS256 signing, full tenant isolation with separate databases, optional two-factor authentication, and encrypted token storage on devices. Every access is logged for complete audit trails.

Simple, Transparent Pricing

No per-message fees. Pick a plan that fits your volume and scale when ready.

Messages are automatically re-routed to other available devices in your fleet. The platform monitors device health in real time and will redistribute pending messages within seconds. When the device comes back online, it resumes processing immediately.
