How to Enable or Disable Cellular Use in Windows 11
You can enable or disable cellular use in Windows 11 to control your PC’s ability to connect to mobile networks using a SIM or eSIM.
This feature allows your Windows 11 device to access the internet via cellular data, much like your smartphone does, providing an alternative connection when Wi-Fi is unavailable or unreliable.
Windows 11 automatically monitors your network quality; if your Wi-Fi signal weakens, it seamlessly switches to your cellular data connection, ensuring you remain online.
For example, this is incredibly useful if you’re working remotely and your hotel’s Wi-Fi suddenly drops, letting you continue your tasks without interruption.
How to Check if Your PC Supports Cellular Data
Not all laptops have a built-in cellular modem. To check, open Device Manager by right-clicking the Start button. Expand the Network adapters section. If you see a device labeled Mobile Broadband, LTE, or 5G, your hardware is ready to go.
Enable or Disable Cellular in Settings
You can manage this feature easily through the Windows settings menu.
- Open the Windows Settings app by pressing the Windows key + I.
- Click on Network & internet in the left-hand menu.

Can I use both Wi-Fi and cellular data at the same time?
