Some Windows 11 devices have a SIM card or eSIM in them that lets you connect to a cellular data network, 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 to connect.
If necessary, check the info that might have come with your Windows device, SIM card, or cellular device for more info about what settings to use.
If your cellular data connection is working correctly, you shouldn't need to change the cellular settings. However, if you're having cellular connection problems, changing one or more settings may help.
The following is a list of key Cellular settings that you can use to try and fix cellular connection problems. Settings vary by Windows 11 device model and mobile operator.
Use this SIM for cellular data
Determines which SIM slot to use for your cellular connection—physical SIM card slot or your eSIM. You can choose the cellular network connection to use for cellular data. For example, you might use one profile for work and a different one for personal use. Or you might choose a different profile if you’re traveling to a new country.
This setting only appears on Windows 11 devices that have both a SIM and an eSIM. For more about using an eSIM, see Use an eSIM to get a cellular data connection on your Windows PC.
To find this setting, select the Start button, then enter settings. Select Settings > Network & internet > Cellular > Use this SIM for cellular data.
Let Windows keep me connected
Determines if your Windows 11 device will automatically connect to the cellular data network when it’s available. Turn it off if you want to manually connect each time you want to use your cellular data connection. Turn it on if you want Windows to manage the connection for you. When it’s on, you’ll connect to cellular data automatically when you’re not connected to another kind of network.
To find this setting, select the Start button, then enter settings. Select Settings > Network & internet > Cellular > Let Windows keep me connected.
A metered connection is an internet connection that has a data limit associated with it. By default, cellular data connections are set as metered. Some apps might work differently on a metered connection to help reduce your data usage. Also, some updates for Windows won't be installed automatically.
If you set a data limit in Data usage settings for your cellular data connection, Windows can help you stay under your data limit and set the metered connection setting for you. For more info about how to set a data limit, see Set your data limit.
If you can’t change the metered connection setting and want to, see Metered connections in Windows.
To find this setting, select the Start button, then enter settings. Select Settings > Network & internet > Cellular > Metered connection.
Data roaming options
Determines if your cellular data connection stays on when your Windows 11 device is outside your mobile operator's network. To help prevent data roaming charges, you can selecting Don't roam.
If you do allow roaming, you can use cellular data when your Windows device is in a roaming area. Depending on your data plan, you might pay more for data you use when roaming.
To find this setting, select the Start button, then enter settings. Select Settings > Network & internet > Cellular > Data roaming options.
Use cellular whenever Wi-Fi is 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. Turn this on if you want Windows to connect you to cellular in these circumstances. If it is turned off, Windows will use cellular only when Wi-Fi is not available. When cellular data is used, it will use data from your data plan and you may incur charges.
To find this setting, select the Start button, then enter settings. Select Settings > Network & internet > Cellular > Use cellular whenever Wi-Fi is poor.
Choose apps that can use your cellular data
To help control your data usage, you can choose which apps can or can’t use cellular data. For example, if you have an app that uses a lot of data, but you don’t use it often when you’re on the go, you might not want that app to use cellular data.
To find this setting, select the Start button, then enter settings. Select Settings > Network & internet > Cellular > Cellular data and apps > Choose apps that can use your cellular data. On the Cellular data screen, do one or more of the following:
Note: The Windows Subsystem for Android™, the Amazon Appstore, and any installed apps might still use cellular data even if they aren’t listed on the above Settings page for Cellular data and apps.

The internet access point name (APN) is the address your Windows 11 device uses to connect to the internet when using your cellular data connection. Usually, the internet APN is set automatically.
If your cellular data connection isn't working and you can't connect to the Internet, type a new internet APN based on your location and mobile operator. If you can connect to a Wi Fi network on your Windows 11 device or have a phone handy, try searching online to find the internet APN settings for your mobile operator.

When prompted, type your SIM PIN. If this is the first time using it, type the default SIM PIN. If you don't know the default SIM PIN, visit your mobile operator's website to see if they list it there. You must restart your Windows 11 device for your cellular data connection to be locked with a SIM PIN.

Unblock SIM PIN
This appears if you're using a SIM PIN and the incorrect PIN was entered three times. When this happens, the SIM will be blocked and can't be used until you unblock it. To unblock it, you’ll need to contact your mobile operator for the PIN Unblocking Key (PUK) code.
Next, select Unblock SIM PIN, and then type the PUK code. If an incorrect PUK code is entered too many times, your SIM card will be permanently blocked, and you'll need to get a new SIM card from your mobile operator.
To find this setting, select the Start button, then enter settings. Select Settings > Network & internet > Cellular > Mobile operator settings > Unblock SIM PINunder Security.
