If you are running Windows 10 Fall Creators Update (version 1709) or above build, you likely have an app called Mobile Plans on your PC. Mobile Plans is a free app from Microsoft designed to help you easily view and cellular data plans and buy them through Windows Store.
As per Windows Store, Windows 10 users can use Mobile Plans app to buy a data plan to get connected to paid Wi-Fi hotspot or cellular network in your area. Users who cannot find a free Wi-Fi hotspot or need a data plan to access the internet on the go can use the Mobile Plans app.
While this is a useful app, not all users buy additional Wi-Fi hotspot or cellular data plans. Besides that, in order to use cellular data service on your Windows 10 device, your device must have a cellular modem which most Windows 10 devices do not have. That is, your Windows 10 device must have a cellular modem as well as a supported SIM card to use cellular data.
Lastly, there is another catch with this app. As you know, paid cellular data plans are not available in all regions or countries. So, the Mobile Plans app might not be able to display plans in your country or region even if there is a built-in cellular modem on your device.
If, like me, you also feel that the Mobile Plans app is not useful, you can uninstall the app from your Windows 10 device. You can either remove it via the Settings app or use a third-party utility such as the CCleaner to uninstall Mobile Plans app from Windows 10.
