Referral Program Terms

For a limited time from November 28, 2018 through January 8, 2019, referrers can earn $100 referral credit per eligible referral for up to $700 in total referral credits, including past referral credits earned to date. Referred users must activate on Google Fi by January 8, 2019, complete 30 days of active service by March 1, 2019, and satisfy the below terms and conditions to qualify for this promotion.

This referral program may end at any time and is subject to these terms. Each eligible referral gets the referring user a $100 referral credit and the referred user a $20 referral credit after the referred user accepts the referral and activates a new Google Fi account for at least 30 days, including paying for 2 months of service on that account. You understand and agree that both the referring user and the referred user can see each other’s names, contact information, and referral status, such as purchase and account activation status. The referring user and the referred user are only eligible to receive a referral credit if they both maintain active Google Fi accounts in good standing for which they pay a monthly fee. Group plan accounts are not eligible for this referral program.

Referral credits may only be used for Google Fi service and will be applied in increments toward monthly service costs such as data, calls, text, and device protection; they cannot be applied to taxes or device purchase or financing, and they are not transferable. If you cancel service, you will not receive a refund for referral credit. Your participation in the referral program constitutes your acceptance of these terms and conditions, and your use of Project Fi is subject to the Project Fi Terms of Service.

This program is only available for U.S. residents ages 13 and older, and requires Google Payments and Google Fi accounts. Referrals and referral credits are not transferable, and are not valid for cash or cash equivalent. Void where prohibited.
