How to Enable or Disable Cellular Use in Windows 11

If your computer has a SIM card or eSIM, you can connect to a cellular data network anywhere you have a mobile signal. This works just like Wi-Fi or hotspot connections. Once you connect, you can browse the web and send emails.

Why use this? Sometimes your Wi-Fi signal is weak or slow. This Windows 11 Dev Build 23471 feature lets your computer automatically switch to your cellular data to keep your internet connection strong.

What happens when done? Your computer will constantly monitor your internet quality. If the Wi-Fi signal drops, Windows will seamlessly switch to cellular data so you do not lose your connection.

You can manage this feature easily through the Windows settings menu.

1. Open the Windows Settings app by clicking the Start menu or pressing the Windows key + I on your keyboard to open the Settings app.
2. Click on Network & internet in the left-hand menu.

3. Click the Cellular tile on the right side of the screen.

4. Find the option labeled Use cellular whenever Wi-Fi is poor.
5. Toggle the switch to On to enable it, or Off to disable it.
