Last December we launched the Project Fi referral program as a way to make sharing Project Fi with friends easier. Many of our users have gone above and beyond with their efforts, sharing Project Fi with friends, online communities, and even strangers at the airport.

As our way of saying thanks, today we’re launching a Fi Referral Challenge. We’ll be awarding Fi subscribers special prizes for their referrals—on top of the standard $20 Fi referral credit per referral. While we’re excited about all of the prizes, we're especially eager to meet the participants who bring the most new subscribers to Project Fi. Our top three referrers will score a trip to Google headquarters and spend time with the Project Fi team.

Here’s a breakdown of what you can earn for the referrals you make from now through September 25:

If you’d like to participate in the the challenge, remember to enter here and share your Project Fi referral code with friends and family by text, email, or on social media.
