Compatibility with Windows Phone

While there is no official Windows phone app for Outline VPN available, the Outline platform uses the Shadowsocks protocol which is compatible with several third-party Windows Phone solutions:

  • Shadowsocks (UWP)
  • Risely for Shadowsocks
  • Simple Shadowsocks Socket5 Client

These apps allow manually configuring and connecting to Outline VPN or other Shadowsocks VPN providers using account details. (Note: Terms may prohibit access.)

Steps to Install and Configure on Windows Phone

For example, with Shadowsocks (UWP):

  1. Download and install app from Microsoft Store. Grant permission requests.
  2. Get access details from VPN provider/server for address, encryption, password.
  3. Open app settings and enter required connection details under manual configuration:
    • Server Address ( or public IP)
    • Server Port number
    • Encryption method (chacha20-ietf-poly1305)
    • Password
  4. Enable system proxy under client options. Set mode to global proxy. Configure proxy port to match app.
  5. Connect to VPN server using toggle switch. Verify connection status.

Connecting to VPN Server from Windows Phone

Once configured, the Windows Phone device can connect to Outline VPN:

  1. Launch Shadowsocks app from the Start screen.
