Smart Tether - Use your Android phone's mobile data on Windows, no hotspot
by•
Smart Tether lets your Windows PC use your Android phone's mobile data over USB or Wi-Fi, with the phone's hotspot and USB tethering left off. Unplug the cable and it switches to Wi-Fi without dropping open connections, so calls and games keep going. A tray icon shows how you're connected. Pair once by QR code. No account, no telemetry. Free and open source (MIT).

Hi everyone 👋
Smart Tether lets your PC use your phone's mobile data without turning on the hotspot. The phone app opens normal mobile-data connections for each one the PC makes and relays the data, with no hotspot or tethering toggle.
What makes it different:
Seamless USB ⇄ Wi-Fi switching; open connections survive the switch and short drop-outs (~30 s)
Stable UDP ports, so voice calls and games keep working
Runs as a Windows service, can start before you sign in
Pause sends Windows back to Ethernet/home Wi-Fi without unpairing
Needs Windows 10 1809+ (x64) and Android 12+. Feedback very welcome, especially on phones I haven't tested.
