You no longer need an invite to sign up for Google’s phone service. The company launched Project Fi about ten months ago and up till now entry was by invite only, even though it wasn’t that hard to score an invite. Nevertheless, the decision to go invite-free reflects Google’s confidence in this service as it opens up Project Fi to whosoever wishes to join.

Starting today, anybody in the United States can sign up for Project Fi. To promote the fact that the service is now open, Google is also offering the Project Fi-compatible Nexus 5X for $199, provided that the phone is bought and activated through this service.

Project Fi is a virtual mobile network that relies on the network provided by T-Mobile and Sprint, it switches automatically based on the best reception available in a particular area, and it provides unlimited calls and texts as well as international texts starting at $20 per month. Customers pay $10 per additional GB of data.

One big caveat with Project Fi is that it’s only compatible with the Nexus 6P, Nexus 6 and Nexus 5X so it’s not like you can use your brand spanking new Galaxy S7 Edge on this service. If you’re enticed by Project Fi you’ll have to dump your current smartphone and opt for one that’s supported.
