## What it is
Low-cost SMS forwarding firmware for ESP32C3 + ML307R 4G modem hardware that automatically forwards received SMS messages to up to five configurable push channels (email, Bark, DingTalk, PushPlus, ServerChan, Feishu, generic HTTP). It includes a web admin UI for configuration, sending SMS, ping-based balance consumption, and AT command debugging.

## Use cases
- forward SMS from a spare SIM card to my phone
- receive verification codes remotely without carrying a second phone
- keep a phone number active by auto-consuming balance
- build a cheap DIY SMS gateway with ESP32
- push incoming texts to Telegram or Bark
- self-hosted SMS notification receiver

## When to choose
- you want an ultra-cheap (~¥28) dedicated device that only receives and forwards SMS
- you need multiple simultaneous push channels with a web configuration UI
- you want number-keeping features like remote SMS and ping-based data usage

## When to avoid
- you need calls, multi-SIM control, open APIs, or general automation - explicitly unsupported
- you need a software-only solution without dedicated hardware
- you need two-way SMS at scale or an SMS gateway API service
