You can now sign up to try Microsoft's upcoming game-streaming service, xCloud, which begins a limited public preview next month.

Invited customers can stream Xbox games on their Android smartphones and tablets. Participants will get free access to titles such as the recently released Gears 5, Halo 5: Guardians, Sea of Thieves, and Killer Instinct.

Eligible gamers will need a 5GHz Wi-Fi or mobile data connection that can reach download speeds of 10Mbps or higher; test users in the US and UK can be on any wireless carrier. They will also need a smartphone/tablet with at least Android 6.0, and a Bluetooth-enabled Xbox One wireless controller.

One of the carriers participating in the test is T-Mobile, which plans on streaming the games using its 4G LTE network. Both companies hope the test will help them refine the technology behind cloud gaming. Microsoft has already been outfitting its data centers with Xbox One components to run the games and send the data online. Broadband providers and carriers such as T-Mobile will then need to seamlessly funnel the data over their networks and down to customer devices without much lag.

The big advantage to cloud gaming is you'll no longer need to buy a $300 video game console; you can simply stream the experience on your existing devices on the go. But on the down side, you're going to be guzzling lots of data. It's why T-Mobile is limiting the xCloud trial to those with an unlimited data plan.

For now, Microsoft is launching the trial for consumers only in the US, UK, and South Korea. "We anticipate many people will register for a limited number of spots and invites may not be sent until several months after registration," the company's xCloud website says.

The preview will last until "customers are consistently reporting a great, fun experience and the technology meets our internal quality standards," Microsoft said in today's announcement. The company will add more game titles to the trial over time.

To register, you'll need a Microsoft account. The company will then send you an email if you've been selected for the trial.

Editor's Note: This story has been updated with more information from Microsoft to clarify the trial is open to US and UK consumers regardless of wireless carrier.
