Dra-Ganzz/Premium-Call ? reverse-engineered prompt

Build me a simple Termux friendly Python app that helps me manage and test phone number notifications in a safe way.

I want a text based menu where I can paste a list of numbers, check which ones are valid, and send a test notification or call request only to numbers I own or have permission to contact. It should be easy to run from the terminal, save basic data locally, and show clear status messages for each number.

Please make it feel polished, with a clean menu, good error handling, and setup instructions that work on Android with Termux. If something needs current package info, look up the latest docs online. Keep it lightweight, reliable, and focused on legitimate testing and contact management, not mass messaging.
