Cellular Data will allow customers with a "Microsoft SIM card" and select Windows 10 devices to purchase data through the Windows Store. However, the store description currently implies that the card will only work with a select number of Windows 10 devices and will be available in France, U.K., and the U.S. initially. The full description reads:

Are you looking for a reliable, convenient way to stay connected everywhere you go, even when WiFi isn’t available? The Cellular data app allows you to connect to a trusted nationwide mobile data network using only your Microsoft account.

Connect with – and pay for – a mobile data plan on your Windows 10 device using only your Microsoft account information. That means no fixed contract and no long term commitments to a mobile network operator. Now you can buy and use mobile data at your own convenience. This is the easiest way to get online using a trusted nationwide network. Purchase a plan via Windows Store anywhere network coverage is available. The Cellular data app can get you connected at any time with a secure, high-speed mobile connection.

This app is designed to work solely with specific Windows 10 devices and requires a Microsoft SIM card.

Service is available in some markets and offers are for domestic plans only – international roaming offers will be available soon....
