New customers get $20 credit on their Google Project Fi account with referral code:
Or you can use this direct referral code link:
When signing up for Google Fi, I learned about their $20 account credit referral program. You also get additional $20 credits whenever you refer someone to Google Fi. My referral code (ACH724) is currently working. After you sign up, they give you your own referral code for handing out to other people. Important: the $20 account credit takes effect after the new customer’s account has been active for 30 days.
Feel free to leave your referral code in the comments below for other new users, and we can all share this incentive.
