Microsoft is planning to make LTE access a little easier soon, thanks to its own SIM card. The software giant is currently testing a cellular data app that lets Windows 10 devices connect to various mobile network operators without a contract. The cellular data app has been published to the company’s Windows Store, but Microsoft has not yet announced its plans for the service.

The app is designed to work on Windows 10 and “requires a Microsoft SIM card,” according to the listing. It’s not immediately clear which markets Microsoft plans to launch its SIM card in, and the pricing of the cellular data. Microsoft is planning to sell plans through the Windows Store, so the data will be tied to a Microsoft Account.

Depending on availability, Microsoft could be planning to create its own mobile virtual networks to allow Windows 10 users to connect to partner carriers. The lack of contracts suggests Microsoft may need to create its own network with partners, but the company could also offer access in a similar method to Apple's own SIM card. We’ve reached out to Microsoft for more information on its mysterious cellular data app, and we’ll update you accordingly.
