farukalpay/SMS-Sender ? reverse-engineered prompt

Build me a Python app that can send SMS messages to one number or a whole list of numbers from the command line.

I want it to feel simple to use, with a clean start screen, prompts for country code and phone number, and a way to load message text and send it through different website based SMS sources. It should support batch sending, show progress while it runs, and let me add my own website config files so I can plug in new providers without rewriting the whole app.

If possible, include proxy support so it can switch between proxies while sending, and make sure it keeps working even if one site fails. I also want a basic example config included, plus the country code data it needs. Keep it in Python, use the existing file structure where it makes sense, and make the setup easy enough to run after installing the requirements. If you need to check current docs or examples online, go ahead.
