Android app forwarding SMS messages to Telegram bot

It is just a handy thing when you work on your laptop. You probably don't want to pick up your phone every time you need to enter an OTP code.

This is parametrized fork of original smsq by Igor Mikushkin

Original repository

Since Igor's backend doesn't seem to work anymore, I decided to set up my own.

This fork allows you to set up your own backend and telegram bot.

Backend installation (optional)

For convenience you can use docker image tarasverq/smsq-backend

Just run it with command
docker run --name smsq -d --env=DOMAIN=<DOMAIN_HERE> --env=BOT_TOKEN=<BOT_TOKEN_HERE> --env=ADMIN_ID=<YOUR_TG_ID_HERE> -p <PORT_HERE>:80 tarasverq/smsq-backend:latest

Variable name	Description
DOMAIN_HERE	Domain with port for tg webhook. Webhook can be set up only on ports 80, 88, 443 or 8443
BOT_TOKEN_HERE	Your bot token obtained from @BotFather
YOUR_TG_ID_HERE	Your TG ID. Easiest way to get it: @username_to_id_bot
PORT_HERE	Host Machine port

Example:
docker run --name smsq -d --env=DOMAIN=domain.com:443 --env=BOT_TOKEN=6531881811:AAF111e3coTifgug03-MdxN2tUEh7kp4Sm4 --env=ADMIN_ID=123321 -p 8888:80 tarasverq/smsq-backend:latest

IMPORTANT: Don't forget to send /start message to your bot before starting up docker image

In case you want to use https (recommended) set up nginx reverse proxy with letsencrypt certs.
Manual

Example nginx conf matching with ports from command above.

server {
    server_name   domain.com;
    location / {
        proxy_pass         http://127.0.0.1:8888;
        proxy_http_version 1.1;
        proxy_set_header   Upgrade $http_upgrade;

        proxy_set_header   Host $host;
        proxy_cache_bypass $http_upgrade;
        proxy_set_header   X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header   X-Forwarded-Proto $scheme;
    }

    listen 443 ssl; # managed by Certbot
    ssl_certificate /etc/letsencrypt/live/domain.com/fullchain.pem; # managed by Certbot
    ssl_certificate_key /etc/letsencrypt/live/domain.com/privkey.pem; # managed by Certbot
    include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot
    ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot
}

Installation client

Just install mobile app from releases

⚠️ WARNING

If you want to use it into long-running background mode, you need to disable Google Play Protect. Instruction
Otherwise, the Google Play Protect service will unload the app every 4 hours because it doesn't have a certification.
Certification requires an android developer account, which I don't have.

Usage

Install Android app
Open the app
Put your bot name to first text field. e.g. my_sms_bot
Put your backend url with ending slash. e.g. https://domain.com/
start forwarding, connect Telegram
Now you receive your SMS messages in this bot!

In case you don't want to set up backend you can use backend deployed by me.
