A "config file" (often ending in extensions like .dt or similar) is a set of pre-configured instructions that tells the exactly how to connect to a specific server. For Airtel users, these files are often tuned to work with specific network ports or bypass local ISP throttling. Key Protocols Supported:
Locate the downloaded file in your device's "Downloads" folder and select it.
When you connect using the config, your phone sends data to the tunnel server via port 443. The server then decrypts the data and forwards it to the open internet. Airtel only sees encrypted noise going to a trusted HTTPS port.
