About Google Fi

Google Fi Wireless, launched by Google on April 22, 2015, began as Project Fi and has since grown into a full-featured mobile service provider. Their plans are designed to meet a range of needs, from unlimited data options to flexible pay-as-you-go choices. With Google Fi, customers benefit from transparent, flexible pricing and the freedom of no annual contracts.

To attract new and returning customers, Google Fi regularly offers promotions. Recent deals have included 50% off the Unlimited Plan for the first three months for new subscribers, savings of up to $650 on select phones through monthly installment plans, and credits for activating new lines or switching from another carrier. For questions or help, you can head to the “Contact Us” section of their website. There, you can request a callback, use the live chat, or fill out a contact form to connect with support.

Frequently asked questions about Google Fi

Share Fi, earn rewards

With Google Fi’s refer-a-friend program, both you and your friend can save. Share your referral code, and your friend gets $60 off their service. Once they stay active for about 30 days, you get credits on your own bill. You can earn up to $600 this way, which adds up fast. Save your referral link and post it in chats or on social media since anyone and everyone could benefit from it!

Trade in and save on a new phone

Instead of letting your old phone sit in a drawer, trade it in with Google Fi for instant credit toward a new one. At checkout, you’ll see an estimate of how much your phone is worth. Just ship it in, and after it’s assessed, the final amount will be applied like a discount. Many users receive their new phone in about five days, making this a quick and cost-effective way to upgrade.

Our advice? Always check the trade-in estimate before shopping. You can also choose to reject it if it’s not what you expected, so you’re not locked in! While we’ve found that values can be surprisingly high for newer models, we’ve also seen older phones fetch a good trade-in value when owners took great care of them. Using screen protectors and a durable case goes a long way in maintaining value for trade-ins.

How do I use a promo code at Google Fi?

It's easy. Just pick your plan or phone, go to checkout, and drop your promo code into the "Promo Code" box before completing payment. Hit Apply and you’ll see the savings right in your subtotal. Our tip: use promo codes early since some are single-use only. That way, you can also confirm the discount is applied before purchase.
