This tutorial will show you how to turn on or off use cellular whenever Wi-Fi is poor in Windows 11.
Some Windows 11 devices have a SIM card or eSIM in them that lets you connect to a cellular data network (ex: 5G), so you can get online in more places by using a cellular signal.
If your Windows 11 device doesn’t have a SIM card or eSIM, you can still connect to a cellular network by plugging in an external cellular device (also called a cellular modem or mobile broadband device). Either way, you must have a data plan from a mobile operator (ex: AT&T, T-Mobile, etc...) to connect.

Starting with Windows 11 version 22H2 KB5030310 Build 22621.2361, Microsoft has added a new toggle in Settings to control whether to use cellular whenever Wi-Fi is available but poor.
Sometimes you might be connected to a slower Wi-Fi network, or you might be in an area where using cellular data would be faster than Wi-Fi. In cases like this, Windows can connect you to the best network based on your current location if Use cellular whenever Wi-Fi is poor is turned on.
When cellular data is used, it will use data from your data plan and you may incur charges.
