Hotspot Bypass VPN 📱💻

A complete solution to bypass carrier hotspot data restrictions and share your internet connection (including VPN) from an Android device to other phones or laptops.

This project is specifically designed to work with 100% compatibility, supporting both standard web traffic and high-performance gaming (e.g., Roblox, Discord, UDP traffic).

🌟 Key Features

📱 Android Application

• Share Mode (Host):
  • Creates a high-performance Wi-Fi Direct hotspot.
  • Bypasses carrier "Tethering" limits by routing traffic through a local proxy.
  • Persistent: Stays active in the background, even when the screen is locked or the app is swiped away.
• Connect Mode (Client):
  • Connects to a "Host" phone and tunnels all system traffic through a VPN.
  • Uses tun2socks for robust, gaming-optimized packet handling.

💻 Laptop Client (Python)

• Two Routing Modes:
  • Simple Proxy: Best for browsers and light web use.
  • Global VPN (TUN): Captures 100% of Windows traffic. Required for games like Roblox.
• Automatic Setup: Downloads necessary drivers (wintun, tun2socks) automatically.
• Lightweight: Runs in a Python virtual environment with a clean GUI.
