Cellular settings in Windows 10

Determines if your PC will automatically connect to the cellular data network when it’s available. Clear the check box if you want to manually connect each time you want to use your cellular data connection. Select it if you want Windows to manage the connection for you. When selected, 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 select Settings  > Network & Internet  > Cellular  > Let Windows manage this connection. This setting is available when you're disconnected from the cellular data network, and it's applied when you select Connect.

Determines which SIM or eSIM profile is used for your cellular data connection. To help control costs, you can choose the cellular network connection to use for cellular data. For example, you might choose one SIM or eSIM profile over another because data costs less. This setting only appears on Windows 10 PCs that have both a SIM and an eSIM.

To find this setting, select the Start button, then select Settings  > Network & Internet  > Cellular  > Use this SIM for cellular data.

Determines if your cellular data connection stays on when your PC is outside your mobile operator's network. Selecting Don't roam can help prevent data roaming charges.

To find this setting, select the Start button, then select Settings  > Network & Internet  > Cellular  > Data roaming options.

The Internet access point name (APN) is the address your PC 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 PC or have a phone handy, try searching online to find the Internet APN settings for your mobile operator.

1. Select the Start button, then select Settings  > Network & Internet  > Cellular  > Advanced options > Add an APN.
2. Next, do one or more of the following:
   • In the Profile name box, type a name for the APN profile.
   • In the APN box, type the address for the APN to use.
   • In the User name box, type the user name for your mobile account.
   • In the Password box, type the password for your mobile account.
   • Select Type of sign-in info, and then select the authentication method that's used.
   • Select IP type, and then select the type of IP address to use.
   • Select APN type, and then select Internet.
3. Select the Apply this profile check box if you want the APN profile to be used right after you save it.
4. Select Save > OK.
5. To go back and view the list of APN profiles you have, select Back, and look under Internet APN.

This displays information about your SIM and cellular data connection. Select Copy to copy the information to paste into an email or elsewhere. This can be helpful if you’re having connection problems and need to send information to your mobile operator or support person.

Determines if you want to use a PIN for the SIM in your PC to help prevent other people from using the cellular data connection when they’re not authorized. After you've set up your SIM PIN, you'll be prompted to type the SIM PIN when you try to connect.

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 PC for your cellular data connection to be locked with a SIM PIN.

If you’ve already set up a PIN for the SIM, type your SIM PIN when prompted, and then select OK.

To find this SIM PIN setting, select the Start button, then select Settings  > Network & Internet  > Cellular  > Advanced options > Use SIM PIN under the Security section.

This appears when you're using a SIM PIN. If you’re using a SIM PIN and decide you don’t want to use a PIN anymore, select Remove SIM PIN, type your current SIM PIN, and then select OK.

To find this SIM PIN setting, select the Start button, then select Settings  > Network & Internet  > Cellular  > Advanced options > Remove SIM PIN under the Security section.

This appears if you're using a SIM PIN. To change your SIM PIN if you’re using one, select Change SIM PIN, type your current SIM PIN in the Current SIM PIN box, type a new SIM PIN in the New SIM PIN box, type the same new SIM PIN in the Confirm new SIM PIN box, and then select OK.

To find this setting, select the Start button, then select Settings  > Network & Internet  > Cellular  > Advanced options > Change SIM PIN under the Security section.

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 if your SIM is blocked, select the Start button, then select Settings  > Network & Internet  > Cellular  > Advanced options > Unblock SIM PIN under the Security section.
