In 2025, mobile data is everywhere. But what happens when your phone runs out of data, or the Wi-Fi network around you is weak? That’s when using your PC’s internet on your mobile with a USB cable becomes a life-saver. This method, known as reverse tethering, allows your computer to share its internet connection directly with your phone.

It’s fast, reliable, and doesn’t drain your battery like Wi-Fi hotspots do. The best part? You don’t need expensive apps or complicated setups. Just a USB cable and a few simple steps.

This guide will cover everything you need to know in 2025 about sharing your PC’s internet with your phone using USB. From step-by-step instructions to advanced tips, we’ll break it all down in a simple way.

Why Use PC Internet on Mobile with USB?

Before jumping into the steps, let’s understand why people still use this method in 2025, even when Wi-Fi is so common.

  1. No Wi-Fi available – Sometimes you’re at work, in a hotel, or on a desktop without a hotspot option.
  2. Save mobile data – If you’re on a limited data plan, using your PC’s internet keeps your mobile data untouched.
  3. Stable and faster speeds – USB connections are often more stable than Wi-Fi tethering.
  4. Better battery life – Unlike Wi-Fi or Bluetooth tethering, USB tethering charges your phone while sharing the internet.
  5. Bypass restrictions – Some workplaces disable Wi-Fi sharing. USB reverse tethering is a way around it.

What You Need Before You Start

To make sure everything works smoothly, here’s a quick checklist:

  • A Windows or Mac computer with an active internet connection.
  • USB cable that connects your phone to your PC.
  • A smartphone (Android or iPhone) with USB debugging or tethering support.
  • Drivers installed (for Android phones, this usually installs automatically when you connect via USB).
  • A little patience – since the setup can be tricky the first time.

Method 1: Share PC Internet to Android via USB (Windows 10/11)

If you’re using Windows, this is the simplest way to share your PC’s internet with your Android phone.

Step 1: Connect Your Phone

  • Plug your Android phone into your PC using a USB cable.
  • On your phone, swipe down the notification panel.
  • Tap USB Preferences and select USB tethering or USB for Internet access.

Step 2: Enable USB Tethering on Your Phone

  • Go to Settings > Network & Internet > Hotspot & Tethering.
  • Toggle USB Tethering on.

Step 3: Configure on Windows

  • Open Control Panel > Network and Sharing Center.
  • You’ll see your mobile device under network connections.
  • Your PC’s internet will automatically be shared with your phone.

Now, try opening a website on your phone. If it loads, you’re good to go!

Method 2: Share PC Internet to Android via USB (Mac)

For Mac users, the process is slightly different because macOS doesn’t directly support reverse tethering. You’ll need a third-party tool.

Step 1: Install HoRNDIS (Legacy Users)

  • In the past, HoRNDIS was used for Android reverse tethering.
  • In 2025, newer alternatives like AndroidToolKit for macOS work better.

Step 2: Connect and Enable Tethering

  • Plug your phone into your Mac.
  • On your phone, enable USB Tethering.
  • Open the third-party tool and select Share Internet via USB.

This will allow your phone to use your Mac’s internet.

Method 3: Share PC Internet to iPhone with USB

If you’re an iPhone user, you can also share your PC’s internet via USB. Apple’s ecosystem makes it straightforward.

Step 1: Install iTunes (Windows Users Only)

  • Install iTunes to ensure iPhone drivers are properly set up.

Step 2: Connect iPhone to PC or Mac

  • Use your Lightning or USB-C cable to connect your iPhone.

Step 3: Enable Personal Hotspot

  • Go to Settings > Personal Hotspot on your iPhone.
  • Turn on Allow Others to Join.
  • Select USB Only if given the option.

Your iPhone will now use your computer’s internet connection directly.

Method 4: Using Third-Party Tools for Reverse Tethering

In some cases, built-in tethering doesn’t work. That’s where third-party tools come in handy.

  1. Reverse Tethering NoRoot (Android) – Allows you to share PC internet without rooting your device.
  2. EasyTether – A paid app, but very reliable. Works on Windows, Mac, and Linux.
  3. PDANet+ – One of the oldest and most stable apps for USB tethering.

These apps provide extra features, like bypassing mobile carrier restrictions.
