How to Enable or Disable Cellular Use in Windows 11
You enable or disable cellular use in Windows 11 to manage your PC’s connection to mobile networks via a SIM or eSIM.
Cellular data access in Windows 11 allows your PC to use a cellular network, just like your smartphone connects to the internet. This feature uses a built-in modem or a USB cellular modem to provide internet access when Wi-Fi is not available.
It provides a crucial backup internet connection when Wi-Fi is unavailable or unreliable.
For instance, Windows 11 can automatically switch to your cellular connection if your Wi-Fi signal degrades, ensuring you remain online. This is especially helpful if you’re working remotely and your primary connection fails.
Open Settings, go to Network & internet, then Cellular. Toggle “Use cellular whenever Wi-Fi is poor” to On to enable or Off to disable. You may also need a mobile data plan and SIM or eSIM.
