Google is now expanding the reach of its Project Fi pre-paid carrier service. Previously, the service was only available to access by those who received an invite, but that is no longer required.

In addition to ditching the invite signups, Google is also running a special for the Nexus 5X. People can buy the phone for as low as $199 for the next month if it is bought and activated with Project Fi. That's for the 16GB model in black and white colors; the 32GB version can be bought via Project Fi for $249 in black, white and ice colors. 24-month financing is still available for $8.29 a month for the 16GB version and $10.38 a month for the 32GB version.

Google has also offered some information on how Project Fi customers have used the service since its launch less than a year ago:

Since launch, more than 15% of our customers have used Project Fi abroad. From Mexico to Montenegro, customers have visited 110 of our 120+ supported countries all while paying the same rate for data that they would in the U.S.

We believe that using Wi-Fi should be seamless which is why we created Wi-Fi Assistant - a tool that automatically connects to high-quality hotspots and helps secure your connection. Over 50% of Project Fi customers are connecting to public hotspots using Wi-Fi Assistant on a weekly basis.
