Quantum Fiber vs CenturyLink (2026)
If a fiber line reaches your exact address, Quantum Fiber is usually the stronger pick: symmetrical speeds on its 500 Mbps and 1 Gig plans, no data caps, no annual contract, and Wi-Fi 7 360 WiFi gear included. CenturyLink remains a sensible choice where fiber hasn't been built yet, since its DSL footprint reaches far more rural and small-town addresses than Quantum Fiber's roughly 17-state map. The deciding factor is almost always what's actually wired to your home, so check both at your specific address before choosing.

If a fiber line reaches your exact address, Quantum Fiber is usually the stronger pick: symmetrical speeds on its 500 Mbps and 1 Gig plans, no data caps, no annual contract, and Wi-Fi 7 360 WiFi gear included. CenturyLink remains a sensible choice where fiber hasn't been built yet, since its DSL footprint reaches far more rural and small-town addresses than Quantum Fiber's roughly 17-state map. The deciding factor is almost always what's actually wired to your home, so check both at your specific address before choosing.
CenturyLink is the legacy consumer brand under Lumen (formerly CenturyLink Communications) and now carries most of the company's copper-based DSL service, while the consumer fiber business was sold to AT&T on February 2, 2026 and rebranded Quantum Fiber from AT&T. In practice that means CenturyLink today is largely where you'll find DSL over existing telephone lines, with availability stretching well beyond Quantum Fiber's fiber map.
Where Quantum Fiber tends to win
- Pure fiber-to-the-home with symmetrical speeds on the 500 Mbps and 1 Gig plans, so uploads match downloads — a real advantage over CenturyLink DSL, which is asymmetric and slows the farther you sit from the exchange.
- Higher ceiling: tiers run from about 200 Mbps up through 1 Gig, 2 Gig, 3 Gig and up to 8 Gig in select areas, versus DSL that often tops out in the tens of Mbps at many addresses.
- No data caps, no annual contract, and no early-termination fee, so you can leave any time without penalty.
- Wi-Fi 7 360 WiFi gateway (plus mesh pods where needed) is included, and self-install is available in many markets in roughly 10 to 15 minutes.
- Refer-and-Earn through Aklamio: you and the friend you refer can each earn up to $100 in cash via PayPal or bank deposit (not a gift card or bill credit), and Quantum Fiber donates $10 to charity per successful referral.
Where CenturyLink has a case
- Much wider availability: CenturyLink's combined DSL-and-fiber footprint reaches far more states and rural addresses than Quantum Fiber's roughly 17-state fiber map, so it's often the only wired option in smaller communities.
- Like Quantum Fiber, CenturyLink generally offers month-to-month service with no annual contract and no data caps, so it isn't locking you in either.
- CenturyLink's long-running 'Price for Life' guarantee on eligible plans has historically held your rate steady for as long as you keep the service at the same address, which appeals to people who dislike promo-price step-ups.

How to switch to Quantum Fiber
Switching to Quantum Fiber is straightforward, and it pays to start from a friend's referral link. First, register on the Aklamio Refer-and-Earn portal and have an existing customer send you their link, or share yours. Then check whether fiber actually reaches your home by entering your exact address at quantumfiber.com, since availability is street-by-street and never guaranteed by neighborhood. If your address is serviceable, order a qualifying internet plan as a new residential customer, then either self-install the SmartNID and 360 WiFi gateway (about 10 to 15 minutes in many markets) or schedule a technician visit. Once you install, activate, and keep service active for 60 consecutive days, Aklamio audits the referral and pays both you and the friend who referred you up to $100 each in cash via PayPal or bank deposit. The full payout can take up to about 90 days. Caps apply: $100 per referee and $500 per referrer per calendar year, and business accounts aren't eligible. To be transparent, the owner of this site may also earn a referral reward if you sign up through a link here.
FAQs
How does the Quantum Fiber refer-a-friend program work?+
You share a referral link (the program runs on the Aklamio platform). A friend orders Quantum Fiber at a serviceable address, gets it installed, and keeps it active for 60 consecutive days. After that, both of you are paid up to $100 in cash — and Quantum Fiber also donates $10 to charity. Always confirm the current terms on quantumfiber.com.
How much is the Quantum Fiber referral reward?+
Up to $100 for the new customer and $100 for the referrer — paid as cash via PayPal or bank deposit (not a gift card or bill credit). Annual caps apply: $500 per referrer and $100 per referee per calendar year.
Is Quantum Fiber available at my address?+
Quantum Fiber is fiber-to-the-home, so it’s available only where the fiber has been built — address by address, across roughly 17 states. Enter your address on quantumfiber.com to check (our referral link drops you into that flow).
When does the referral reward arrive and how?+
It’s tied to the friend’s service, not their order: they must install and stay active for 60 consecutive days, then Aklamio audits the referral and pays both parties as cash to PayPal or a linked bank account. Full payout can take up to about 90 days.
