How to check Quantum Fiber availability at your address

Quantum Fiber availability is decided street by street, so the only answer that matters is what your specific address shows on the official checker. This guide walks you through running that check correctly, then explains what happens next: the plans and speeds you may see, how install works, the AT&T rebrand, and the 60-day path to up to $100 cash through Refer-and-Earn.

Quantum Fiber availability is decided street by street, so the only answer that matters is what your specific address shows on the official checker.

How to actually check your address (and why your neighbor's result doesn't count)

Go to quantumfiber.com and enter your full address — house or unit number, street, city, and ZIP. Fiber is built out one block at a time, so coverage is strictly address-specific. A home across the street, or even the unit next door in the same building, can have a different result than yours, which is why you should never rely on a friend's experience or a general claim that a neighborhood is "covered." Enter the exact place you want service installed. The checker returns one of a few outcomes: service is available now (you can order online), it's coming soon to your area, or it isn't available yet at that address. If you rent or recently moved, re-check periodically, because Quantum Fiber continues expanding its footprint. Availability currently spans roughly 17 states — Arizona, Colorado, Florida, Idaho, Iowa, Minnesota, Montana, Nebraska, Nevada, New Mexico, North Dakota, Oregon, South Dakota, Utah, Washington, and Wyoming — with strong presence in metros like Las Vegas, Phoenix, Denver, Minneapolis/St. Paul, Seattle, Portland, and Omaha. Being in one of those areas is a good sign, but it never guarantees your specific address qualifies.

What you'll see if it's available: plans, speeds, and pricing

If your address qualifies, you'll typically be offered a range of fiber-to-the-home tiers: around 200 Mbps, 500 Mbps, 1 Gig, 2 Gig, 3 Gig, and up to 8 Gig in select areas. The 500 Mbps and 1 Gig plans are symmetrical fiber, meaning upload speeds match download — genuinely useful for video calls, uploading large files, cloud backups, and gaming. Note that Quantum Fiber's own footnote excludes the 2 Gig and higher tiers from the symmetrical claim, so don't assume identical up/down on the very top tiers. Indicative pricing runs from about $50 for 500 Mbps and roughly $75 for 1 Gig up to around $165 for 8 Gig, though promotions vary by market and over time, so treat these as ballpark figures rather than quotes. The terms are refreshingly simple: no annual contract, no early-termination fee, and no data caps. A 360 WiFi gateway (a Wi-Fi 7 device, with mesh pods added where a home needs them) is included. Whichever exact plan and price you see at checkout is what governs — the checker is the source of truth, not this guide.

Install: self-install vs. a technician visit

How you get connected depends on your address and what's already wired to your home. In many markets, self-install is available: if a SmartNID (the fiber network interface) is already in place, you plug in and activate the 360 WiFi gateway yourself, usually in about 10 to 15 minutes, with no appointment window to wait around for. The app and on-screen prompts walk you through activation. Where the fiber drop or interior wiring isn't ready, a technician visit is scheduled instead to run the connection and set up your equipment. During the availability and ordering flow you'll generally find out which path applies to your address. If you're choosing between dates, a self-install option tends to be faster and more flexible; a technician visit takes a bit more coordination but handles the physical groundwork for you.

The AT&T rebrand — what changed and what didn't

As of February 2, 2026, AT&T acquired Quantum Fiber's consumer fiber business from Lumen (formerly CenturyLink), and the service is now branded "Quantum Fiber from AT&T." The important part for customers: the network and the plans are unchanged. Only the ownership and branding changed — your speeds, equipment, and the address-by-address footprint are the same as before, so the availability checker still works exactly as described here. A common point of confusion is whether Quantum Fiber and AT&T Fiber are now the same thing. They are not. Both are owned by AT&T, but they remain distinct products with different network footprints. An address that can't get one may be able to get the other, and vice versa. If you're comparing the two, check each on its own — being eligible for Quantum Fiber from AT&T tells you nothing about AT&T Fiber availability at that address, and the reverse is equally true.

Refer-and-Earn: up to $100 cash each, and the 60-day wait explained

Once you're a customer, Quantum Fiber's Refer-and-Earn program (run through the Aklamio platform) lets both you and a friend you refer earn up to $100 each — paid as actual cash via PayPal or bank (ACH) deposit. It is not a gift card, not a prepaid Visa, and not a bill credit. Quantum Fiber also donates $10 to charity per successful referral. To participate, register on the Aklamio portal before making your first referral, then share your link. In the interest of transparency, the owner of a site sharing a referral link may earn a referral reward too. Here's the part that causes the most searcher anxiety: the reward isn't instant. Your friend must be a new residential customer at a serviceable address, order a qualifying internet plan, install and activate, and then keep service active for 60 consecutive days. Only after that does Aklamio audit the referral and release payment to both parties — and the full payout can take up to about 90 days. So the 60-day clock is a hold-and-verify period, not a delay or a problem. A few caps to know: $500 per referrer per calendar year, $100 per referee per calendar year, and business accounts are not eligible. The cleanest path is to first confirm your address at quantumfiber.com, get installed, and once you're set up, use a referral link so both you and your friend can collect up to $100 cash each.
