Why can’t I connect or browse using my mobile broadband connection?

Here are the most common problems you might encounter when using a mobile broadband connection, and the steps you can take to solve them.

This could be because:

    Your subscriber identity module (SIM) or device is locked, not readable, or no longer valid.

    Your mobile subscription has expired or isn't activated.

    You're in an area where there's no network signal.

To try to find the exact cause of the problem and a solution, start the Network troubleshooter by following these steps:

    Click to open Network and Sharing Center.

    In the left pane, click Change adapter settings.

    Right-click the mobile broadband connection, and then click Diagnose.

If you have a signal and can see the connection in Network Connections, but the connection to the mobile broadband network fails, it could be because:

    You don’t have a valid data subscription.

    The access point name (APN), user name, or password used for the connection isn't valid.

    You're roaming and the currently selected network operator doesn’t allow data services or you don’t have roaming enabled for data services.

To try to find the exact cause of the problem and a solution, start the Network troubleshooter by following these steps:

    Click to open Network and Sharing Center.

    In the left pane, click Change adapter settings.

    Right-click the mobile broadband connection, and then click Diagnose.

Depending upon the service plan you have, access to certain sites (IP addresses), ports, and types of services might be blocked by your mobile operator. Contact your mobile operator to make sure you have the service necessary to use the program over the mobile broadband connection.

Certain mobile operators have separate settings for Internet access using a data card versus a phone. Contact your mobile operator to make sure that your subscription allows using a data card and that you have the correct settings.
