## What it is
SMSSync is a free and open-source Android application that turns any Android phone into an SMS gateway by forwarding incoming SMS messages to a configured web service URL. It supports keyword filtering, phone number whitelisting/blacklisting, auto-replies, scheduled syncing, and multiple sync URLs with HTTP basic authentication.

## Use cases
- turn an android phone into an sms gateway
- forward incoming sms messages to a web service url
- build an sms-based alert or survey system without a paid gateway
- auto-reply to incoming text messages from a server
- filter sms by keyword or phone number before syncing
- relay sms from the field to a backend over http

## When to choose
- you need a low-cost SMS gateway using commodity Android hardware
- you want an offline-capable SMS relay for areas without internet-only messaging
- you need keyword filtering, auto-replies, and multiple sync endpoints on-device

## When to avoid
- you need high-throughput SMS sending (Android caps outgoing SMS at 100/hour)
- you need a maintained solution - the latest release is from 2021 and development appears dormant
- you need a server-side or cloud-hosted SMS gateway rather than a phone-based one
