Quantum Fiber vs Google Fiber is a fiber-against-fiber choice, so speed type rarely decides it. Price structure does. Quantum Fiber, now owned by AT&T, advertises 1 Gig at $50 a month through new-customer discounts, while GFiber, the new name for Google Fiber, charges $70 for 1 Gig, a price it says has not changed since 2012.[1][2]
Both companies changed hands or announced deals this year. Read that section before trusting older reviews, then check your address with each provider.
Who owns each provider now
Lumen completed the sale of its consumer fiber business in eleven states, including Quantum Fiber, to AT&T on February 2, 2026.[3] Lumen kept its copper-based consumer services, so CenturyLink DSL is a separate product from Quantum Fiber.[3] Quantum's site now brands the service "Quantum Fiber from AT&T."[1]
GFiber agreed on March 11, 2026 to combine with Astound Broadband under majority ownership by the investment firm Stonepeak, with GFiber's executives leading the combined company.[4] The deal needed regulatory approvals and was expected to close in the fourth quarter of 2026; we found no completion notice on GFiber's site on October 20, 2026.[4] Our Astound Broadband guide covers the other half of that deal.
Where Quantum Fiber and GFiber overlap
Our FCC data (filings as of December 30, 2025, before the AT&T sale closed) lists Lumen and Google Fiber together in places such as Seattle, Denver, Lakewood, Mesa, Chandler, Omaha, Bellevue in Nebraska, Des Moines, West Des Moines, Council Bluffs, Salt Lake City, Provo and Pocatello.[5] GFiber's current city list includes most of those, plus Queen Creek, Westminster, Wheat Ridge, Logan and Metro Las Vegas.[2]
Lumen's listing can include copper service, and both companies build neighborhood by neighborhood.[5] A shared city does not mean both fiber networks reach your home.
Price side by side, October 20, 2026
| Speed tier | Quantum Fiber | GFiber |
|---|---|---|
| 1 Gig | $50 a month after a $25 new-customer discount and $5 bank AutoPay discount; standard rate $80 | $70 a month |
| Around 3 Gig | 3 Gig at $70 after a $30 discount and $5 AutoPay, in select markets | 3 Gig at $100 a month |
| Upload speed | Equal to download, except on the 2 Gig plan | Equal to download on 1, 3 and 8 Gig |
| Extra charges named | Taxes and fees; paperless billing required | Taxes and a local access fee |
Table sources: Quantum Fiber's offer details and GFiber's plan page.[1][2] At 1 Gig the advertised gap is $20 a month.[1][2] That gap only holds while Quantum's discounts apply, which is the next question.
The question that decides it: how long does Quantum's discount last?
Quantum describes its 1 Gig price as a $25 monthly discount off an $80 standard rate, plus $5 off for paying by AutoPay from a bank account.[1] Its offer text does not say how many months the new-customer discount runs, and it says pricing can change.[1] If you switch from a bank account to a card, the standard monthly rate applies.[1]
GFiber's pitch is the opposite: one price, with the router included.[2] Use this worksheet with your written quotes:
- Quantum Fiber: How many months does the $25 discount last, and what is the monthly price after it ends?
- Quantum Fiber: Will I pay anything for the WiFi equipment after the first period?
- Quantum Fiber: Is my address fully fiber, or does it use a non-fiber link from the curb?
- GFiber: What is the local access fee at my address?
- GFiber: Is my building or street live now, or still under construction?
- Both: What is my total for the first 12 months and for months 13 to 24?
If Quantum's answer to the first question is about a year, compare a two-year total rather than the first bill.
Equipment and installation
Quantum includes 360 WiFi at no additional cost, with the technician deciding how many extender pods your home needs.[1] Technician installation is included, and Quantum absorbs the first $1,500 of any construction charges, asking your approval before charging more.[1] Quantum also notes that in limited cases it reaches the home with a non-fiber connection from the curb.[1]
GFiber includes its router, or lets you connect your own, and offers either self-setup with its app or free professional installation.[2] If you cancel, return GFiber equipment within 60 days to avoid a replacement fee.[2] Our self-install vs technician guide helps you decide which setup suits your home.
Bundles and budget plans
Quantum takes $20 a month off an eligible AT&T Wireless unlimited plan when you also have Quantum Fiber.[1] Where available, it also sells Simply Fiber, 200 Mbps at $30 a month for households in programs such as SNAP, Medicaid or SSI.[1] GFiber's listed prices are not tied to a bundle or a payment-method discount.[2]
Our verdict
Choose Quantum Fiber if your household already uses AT&T Wireless or you qualify for Simply Fiber, and get the length of the discount in writing. Choose GFiber if you prefer a price that does not depend on a promotion or payment method, or if you want the 8 Gig tier GFiber lists at $150.[2] For more fiber matchups, see AT&T Fiber vs Google Fiber.
