## What it is
An Android application that turns a smartphone into an SMS and MMS gateway, exposing a REST API for sending messages programmatically and webhooks for receiving incoming messages. It supports local, public cloud, and self-hosted private server modes, with end-to-end encryption, multiple SIM support, scheduled messages, and SMPP/SMTP bridges.

## Use cases
- send sms messages programmatically from my app via an android phone
- receive incoming sms as webhooks for two-factor authentication codes
- self-host an sms gateway without a paid sms provider
- send automated sms notifications from a server using a sim card
- integrate sms sending into home automation or iot systems
- bridge email or smpp traffic to sms

## When to choose
- you want low-cost SMS sending using an Android phone and SIM card instead of a paid SMS API
- you need to receive SMS (e.g., OTP codes) and forward them to your systems via webhooks
- you need privacy-sensitive messaging with a self-hosted server and end-to-end encryption
- you need multi-SIM, scheduled messages, or SMPP/SMTP integration

## When to avoid
- you need high-volume, carrier-grade SMS delivery with guaranteed throughput
- you cannot dedicate an always-on Android device with an active SIM
- you need delivery to international recipients at scale where aggregator services are more reliable
- your target device lacks Google Play Services and you rely on cloud mode push (though SSE fallback exists)
