SMS Gateway App

Overview

This application runs a socket server on your phone that listens for a message and number to send. This allows you to use your real phone to send messages in a programatic way.

Installation

Grab the apk from the bin folder, once it's open, run the example command with your devices IP address.

Usage

Once the app is running, it will start a socket server listening for incoming SMS requests on your local IP address at port 5000. You can send messages to this server using any terminal.

Sending a Message from the Terminal

To send a message, you can use the netcat command. Here’s the syntax:

echo '{"to_number": "1234567890", "message_body": "Hello from the terminal!"}' | nc YOUR_IP 5000

Replace YOUR_IP with the IP address of the machine running the SMS Gateway App.

Successful Message Response

Upon successful sending of the message, you will receive a JSON response similar to the following:

{
    "status": "success",
    "recipient": "1234567890",
    "message": "Hello from the terminal!"
}

Using Python to Send messages to multiple numbers

import socket
import json

# Replace with the actual IP address of the machine running the SMS Gateway App
SERVER_IP = "YOUR_IP"  # e.g., "192.168.1.10"
SERVER_PORT = 5000

# List of recipients and message body
recipients = ["1234567890", "0987654321", "1122334455"]
message_body = "Hello to all recipients!"

def send_sms(to_number, message_body):
    # Create a socket connection
    with socket.socket(socket.AF_INET, socket.SOCK_STREAM) as sock:
        sock.connect((SERVER_IP, SERVER_PORT))
        
        # Prepare the JSON payload
        payload = {
            "to_number": to_number,
            "message_body": message_body
        }
        
        # Send the payload as a JSON string
        sock.sendall(json.dumps(payload).encode('utf-8'))
        
        # Receive the response
        response = sock.recv(1024)
        print(response.decode('utf-8'))

# Send messages to each recipient
for number in recipients:
    send_sms(number, message_body)
