Need an internet connection for your PC or laptop, but don't have access to public Wi-Fi? The solution is simple: connect your smartphone's mobile internet connection to your PC. This process is known as tethering.

While tethering with your laptop or tablet may be faster than the public network in your favorite cafe, it can have its own problems. Here's what you need to know about tethering with Android and how to connect your mobile internet to your PC.

What Is Tethering?

Tethering is the term for connecting your mobile device to your computer, so your PC can get online via your phone's mobile data connection. It works via USB, Bluetooth, or Wi-Fi.

In the pre-iPhone days, this meant using an old-style feature phone to call a number that gave internet access anywhere. Some cell phones could share their internet connection, enabling you to get online via the device network's APN.

Following the release of the iPhone in 2007, many cell phone networks began charging extra for tethering plans. Fortunately, this money-grabbing practice has since been phased out almost completely—these days, tethering is usually free aside from using your data allowance.

Android Mobile Tethering Options Explained

Android owners have three tethering options to share a mobile internet connection with their laptop, tablet, or even desktop PC:

  • Connect via Bluetooth
  • Use your phone as a wireless hotspot
  • Connect your phone to your computer via USB

Below we'll look at each of these to discover which method will drain your battery quickest, and which transfers data fastest.

Before proceeding, make sure you have enabled mobile internet on your phone. It's important to note that mobile signal strength will impact your connection speed. Using tethering can also result in your phone's battery level decreasing quickly; wireless tethering is particularly power-intensive.

We provide speed results from for comparison. The actual speeds you get will depend on various factors, including what phone you're using and the speed of the mobile network you're connected to. We were on 4G. 5G will obviously be a lot faster.

1. How to Connect Mobile Internet to a PC With a USB Cable

Mobile phones have long had a modem feature, allowing you to hook up the device to your computer using USB tethering. This lets you share the mobile internet connection over a wired connection with your laptop or other devices.

It's easy to do when you're using Windows. Connect the USB cable that you use for charging your phone to your computer, then plug it into the phone's USB port.

Next, follow these steps to configure your Android device for sharing mobile internet. Some of the menus may be slightly different depending on the device and Android version you're using, but the general instructions are the same on all models.

  1. Open Settings > Network and internet > Advanced > Hotspot and tethering. You can also tap the notification that appears when you connect the device.
  2. Tap the USB tethering slider to enable it. If this appears grayed out, make sure the USB cable is properly connected on both ends.
  3. The Hotspot and tethering warning will appear, informing you that continuing will interrupt any existing data transfers between your phone and PC.
  4. Tap OK to proceed.

A notification icon should appear to confirm that tethering is active. In testing, we found the following results:

  • Speed: 97Mbps download, 2.02Mbps upload, with an average ping of 66ms.
  • Battery Impact: The effect on your phone's battery depends on whether your laptop is plugged in or not. If it is, battery decrease should be slow to non-existent, as the phone will slowly charge through the USB connection.

If your computer is running on its battery, your phone will potentially drain the computer's battery, rather than its own.

2. Use Bluetooth Tethering With Mobile Internet

Want to know how to connect mobile internet to a PC without a USB cable? The answer is to use Bluetooth. The short-range wireless technology has enough bandwidth to route data to and from your phone and a paired device.

Start by pairing your phone with your computer:

  1. Open your Android phone's Bluetooth settings. You can do this by long-pressing the Bluetooth icon in Quick Settings, or browse to Settings > Connected devices.
  2. Select Pair new device, which will make your device discoverable.
  3. Now, on your Windows computer, press Win + I to open the Settings app.
  4. Here, select Devices > Bluetooth & other devices.
  5. Switch Bluetooth to On if it's not already. Click Add Bluetooth or other device followed by Bluetooth.
  6. Select your phone when it appears and walk through the pairing steps. If you run into problems, see our guide to setting up Bluetooth in Windows 10—the same steps can be used in Windows 11.
  7. Once paired, on your phone, open Settings > Network and internet > Hotspot and tethering and turn on Bluetooth tethering.

Once the phone is paired with your computer, you can share the mobile internet connection:

  1. Expand the Windows System Tray to find the Bluetooth icon, right-click this, and select Join a Personal Area Network.
  2. In the resulting menu, find your phone's icon and right-click it.
  3. Choose Connect using > Access point.

Your phone should then display a notification that Bluetooth tethering is active. Our testing found:

  • Speed: 3.5Mbps download, 0.78Mbps upload, with an average ping of 289ms.
  • Battery Impact: Heavy Bluetooth use really puts pressure on your battery. Ten minutes of usage ate up about 5% of the charge on my phone.

3. How to Connect Your Mobile Internet to a PC Wirelessly

Combining the wireless benefits of Bluetooth with the speed of USB, connecting your phone as a Wi-Fi hotspot is perhaps the most popular tethering option.

Using your mobile internet and Wi-Fi connection, your phone creates a private network to connect your devices with a secure password. It's definitely the most convenient choice. To set up Wi-Fi tethering:

  1. Open Settings > Network and Internet > Advanced > Hotspot and tethering.
  2. Tap Wi-Fi hotspot (called Portable hotspot on some phones).
  3. At the next screen, switch the slider On.
  4. You can then adjust options for the network on this page. For example, change the Hotspot name, Security type, or open the Advanced options to turn off the hotspot automatically when no devices are using it.
    1. On some devices, you'll need to open the Configure hotspot menu to change these options.
  5. Tap the Hotspot password (sometimes called Show password) box to view the password, if needed.

Then, on your Windows PC:

  1. Press Win + I to open Settings.
  2. Go to Network & Internet > Wi-Fi.
  3. Click Show available networks and browse to find the network your phone created. (You can also do this by clicking the wireless internet icon in the System Tray).
  4. Select the network and click Connect.
  5. Input the password as displayed on your phone (making any other changes as required) to establish the connection.
Tether phone in Windows

Here are the results we found from this option:

  • Speed: 10Mbps download, 4.45Mbps upload, with an average ping of 55ms.
  • Battery Impact: As with Bluetooth tethering, heavy use reduced battery by around 5% in 10 minutes. Standard usage seems better with Wi-Fi tethering, however, and could potentially last around 5-6 hours.

Once you've set up wireless tethering for the first time, it's easy to activate again. Open the Quick Settings panel on your phone by swiping down from the top twice. Tap the Hotspot button, then wait for your computer to connect. As long as you don't change the network name or password, it should reconnect automatically.

The big advantage to using Wi-Fi for tethering is that it works with any device. Once you've set up the wireless hotspot on your Android phone, you can connect a Mac, a Chromebook, an iPad, or anything else. Just connect to it in the same way you'd connect to any other wireless network.

How to Connect an iPhone Mobile Hotspot to a PC

Not using Android? Need to borrow a phone to connect your PC to the internet and only have an iPhone available? iPhones have a hotspot mode that you can enable at Settings > Personal Hotspot. This is a Wi-Fi hotspot that any wireless-enabled device can connect to.

For further compatibility, iOS also supports Bluetooth and USB tethering, just like Android. For full details on how to connect the mobile internet from an iPhone to your computer, check out how to use the hotspot feature on your iPhone.

Mobile Tethering? Use USB for Best Battery Life

Now you know how to connect mobile internet to your computer, using Wi-Fi, USB, or Bluetooth. But which is best?

Our tests show that USB tethering is the option that drains your phone's battery the slowest. Meanwhile, Bluetooth offers the worst speeds. Thanks to improvements in Bluetooth technology, though, its impact on battery is acceptable.

Stuck choosing between a Wi-Fi hotspot and USB tethering? Well, USB isn't the fastest at everything, making Wi-Fi the best all-around option. But if Wi-Fi isn't available, relying on USB tethering is your best alternative.
