Barebone background service that forwards your incoming new SMS (text message) into a chat with a telegram bot. This program does not connect to any intermediate server, it simply issues a new request to telegram bot API each time the phone gets a new SMS.
Only tested on
- Oneplus 5T on Android 10 (dual SIM)
- Oneplus 7t on Android 11 (dual SIM)
- Pixel 3 on Android 11
You'll need (1) a telegram bot key (2) the telegram chat id to which you want the bot to forward. You should be able to follow https://dev.to/rizkyrajitha/get-notifications-with-telegram-bot-537l to obtain your telegram bot key and chat id.
You'll also want to turn off battery optimisation for this APP to avoid it being killed by the system.
