NetBridge: Using iPhone Data on a Windows PC

I was looking for a way to use my iPhone’s T-Mobile data on my Windows PC without buying tethering software. I tried NetBridge, and it works with my setup. I’m saving the project here with the downloads and a short setup guide.

What NetBridge does

NetBridge runs a local relay on your iPhone. Its Windows companion connects to that relay and routes the PC’s traffic through the phone. The developer, Korporate1k, maintains the project’s instructions on GitHub.

My setup is an iPhone, T-Mobile mobile service, and a Windows PC. My result is a working connection; carrier-side usage accounting and longer-term reliability still need separate testing.

Basic iPhone-to-Windows setup

1. Install the iPhone beta. Open the NetBridge TestFlight invitation on your iPhone and follow the installation prompts.
2. Download the Windows companion. The official releases page provides an x64 ZIP for Intel/AMD PCs and an ARM64 ZIP for ARM PCs. The developer lists 64-bit Windows 10 or 11.
3. Extract the entire ZIP. Keep NetBridge.exe and wintun.dll in the same folder. The app needs administrator access to create its network adapter.
4. Start the phone relay. In NetBridge on the iPhone, open Dashboard → Start relay and keep the app open.
5. Connect the PC. For a phone-data setup, join the iPhone’s Personal Hotspot. Open NetBridge on Windows and select your iPhone under Nearby.
6. Use the displayed address if needed. If discovery fails, choose Enter address manually and copy the address and port from the iPhone. Enter the relay login if prompted.

These steps follow the developer’s current Windows instructions. For other connection arrangements, including a shared Wi-Fi network or supported router, use the project guide.

Keep the beta current

The iPhone app is distributed through TestFlight. Apple gives each beta build a testing period of up to 90 days, so install updates when available. The invitation page explains how beta installation and updates work.
