How to Enable or Disable Cellular Use in Windows 11
Cellular use in Windows 11 lets you control your PC’s connection to mobile networks, using either a physical SIM card or an eSIM.
This feature allows your computer to connect to a cellular network, similar to how your smartphone accesses the internet. It uses a built-in modem or a separate USB cellular modem to provide internet when Wi-Fi is not available.
Cellular data can act as a vital backup internet connection. For example, Windows 11 can automatically switch to your cellular connection if your Wi-Fi signal weakens, keeping you online.
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.
