iPhones and Android phones have a hidden internet sharing feature that’s more secure than a Wi-Fi hotspot — here’s how to use it

2025 was a big year for me. I traveled to cover events like MWC 2025 and IFA 2025, along with plenty of other smartphone launches. One thing I quickly realized while moving between all these places is just how unreliable the internet can be.

Wi-Fi outside my home, even in places like cafes, airports, and malls, is often patchy at best and a privacy risk at worst. Sure, I can rely on a VPN to make it more secure, but the connection being unreliable to begin with still makes it far from ideal for social media, work, or even staying in touch with friends and family back home.

USB wired hotspot sharing is seriously underrated

For months, I've been using my iPhone as a portable Wi-Fi hotspot whenever I travel. I usually pick up an unlimited data plan and turn on Wi-Fi tethering on one of my phones to keep all my devices connected. Recently, though, switching to a wired hotspot has fixed a lot of problems for me.

The biggest improvement has been battery life. Running a Wi-Fi hotspot all day meant I'd need to charge my iPhone during the day, which is especially stressful when you are traveling in a foreign country.

With my iPhone plugged into my Mac via USB and used as a hotspot, it not only shares internet with my laptop but also charges at the same time. That means my iPhone stays topped up while I work, even when hotspot usage is heavy.

Moreover, because it's a wired connection, it's also far more reliable than a Wi-Fi hotspot. You don't have to worry about your laptop's Wi-Fi acting up, speeds dropping because your phone is overheating, or interference from crowded wireless channels.

On top of that, it's also a big win for privacy. Using a wired hotspot means my phone is not broadcasting a Wi-Fi network to everyone around me. My iPhone and the connected device stay secure, without exposing a network name in public spaces. Sure, you can hide the SSID on a Wi-Fi hotspot, but that quickly becomes annoying when connecting new devices.

USB tethering is genuinely one of the most underrated ways to share internet from your phone to your computer. Here's how you can set it up on your devices.

How to use a wired USB hotspot on your iPhone

Setting up USB tethering on an iPhone is almost as simple as turning on a Wi-Fi hotspot, and you can get started in just a few steps. Here's how to do it.

1. Enable Personal Hotspot on your iPhone

Before you can start sharing an internet connection from your iPhone to your computer, you need to enable Personal Hotspot. This allows your iPhone to share its mobile data connection with other devices.

To do this, head over to your iPhone's Settings app and tap on Personal Hotspot. Inside the Personal Hotspot settings, turn on the toggle that says Allow Others to Join.

Alternatively, you can also enable Personal Hotspot directly from Control Center. Just tap the beacon icon (the blue rings with a white triangular cutout at the bottom) so it lights up.

2. Connect your iPhone to your computer

Next, connect your iPhone to your computer using a USB cable. If this is your first time doing this, your iPhone will ask you to trust the connected device. Tap Trust and enter your iPhone's passcode to continue.

3. Enable the right settings on your computer

If you own a Mac, and have used the Wi-Fi hotspot on your iPhone before, your Mac might automatically connect over Wi-Fi. To make sure you are using USB tethering instead, disable Wi-Fi on your Mac.

Then, open the System Settings app and go to Network from the left sidebar. You should see your iPhone listed as iPhone USB.

If it does not appear, click the three-dot menu at the bottom, select Add Service, choose iPhone USB from the Interface dropdown, and tap Add. Once added, your Mac will recognize the iPhone as a wired connection, and the internet should start working immediately.

On a Windows PC, connect your iPhone using a USB cable, then install the Apple Devices app from the Microsoft Store. Sign in with the same Apple account used on your iPhone.

Once installed and signed in, your iPhone will work as a USB tethering device without any additional workarounds. You may need to disable Wi-Fi on your PC to ensure it uses the wired connection.

How to set up a wired USB hotspot on Android

If you're using a Google Pixel 10, Samsung Galaxy S25 Ultra, or most other Android phones, you can also get USB tethering up and running in just a few minutes.

1. Connect your Android device to your computer

Start by connecting your Android phone to your computer using a USB cable. On some devices, you may be prompted to unlock your phone or enter your password to allow the connection.

2. Enable USB tethering on your Android phone

Once connected, you should see a notification on your phone showing how the USB connection is being used.

Tap on that notification and select USB tethering from the following menu. This will allow your phone to share its mobile data connection over the cable.

3. Configure USB tethering on your computer

On Windows, USB tethering usually starts working immediately after you enable it on your phone. In some cases, you may need to turn off Wi-Fi to make sure your system uses the wired connection. Your Android phone should show up as a wired network in the system tray.

On a Mac, the process is similar to setting up an iPhone. Open the System Settings app, disable Wi-Fi, and then go to Network from the left sidebar. Click the three-dot menu at the bottom and select Add Service.

From the Interface dropdown, choose your Android device's name and tap Add. Once added, your Mac should recognize your Android phone as a wired Ethernet connection, and the internet should start working.

It's worth noting that this process may not work with all Android phones on macOS. Some Android phones don't support the CDC NCM protocol, which is required for USB tethering to work properly on a Mac, so you'll have to rely on Wi-Fi hotspot on those devices.

That's all you need to turn your phone into a wired internet connection for your computer. Do keep your data limits in mind, though, since not every mobile plan offers unlimited data. If you plan to use this frequently, it may be worth opting for an unlimited data plan to stay fully covered.
