Quantum Fiber vs AT&T Fiber (2026)
If Quantum Fiber reaches your exact address, it is a strong fiber pick: symmetrical speeds on its 500 Mbps and 1 Gig plans, no annual contract, no data caps, and a Wi-Fi 7 gateway included. AT&T Fiber is an excellent, widely available fiber service too, often with deeper bundle options and a larger national footprint. Since both are now AT&T-owned but remain distinct networks, the real deciding factor is which one actually serves your street, so check your address with both before you choose.

If Quantum Fiber reaches your exact address, it is a strong fiber pick: symmetrical speeds on its 500 Mbps and 1 Gig plans, no annual contract, no data caps, and a Wi-Fi 7 gateway included. AT&T Fiber is an excellent, widely available fiber service too, often with deeper bundle options and a larger national footprint. Since both are now AT&T-owned but remain distinct networks, the real deciding factor is which one actually serves your street, so check your address with both before you choose.
Quantum Fiber is now branded "Quantum Fiber from AT&T" after AT&T acquired its consumer fiber business from Lumen (formerly CenturyLink) on February 2, 2026; the network and plans are unchanged, only ownership and branding shifted. As a result, Quantum Fiber and AT&T Fiber are both AT&T-owned but remain distinct products running on separate network footprints, so being covered by one does not mean you are covered by the other.
Where Quantum Fiber tends to win
- Full fiber-to-the-home with symmetrical upload and download on the 500 Mbps and 1 Gig plans, which is ideal for video calls, cloud backups, and uploading large files.
- No annual contract and no early-termination fee, so you can leave anytime without penalty.
- No data caps on any plan, so streaming, gaming, and working from home never hit an overage.
- A Wi-Fi 7 360 WiFi gateway is included (with mesh pods where needed), and self-install is available in many markets in about 10 to 15 minutes.
- Switching through a referral link means both you and the friend who refers you can each earn up to $100 in cash via PayPal or bank deposit, not a gift card or bill credit.
Where AT&T Fiber has a case
- AT&T Fiber generally has a much larger and more established national footprint, so it is available at far more addresses across more states than Quantum Fiber.
- AT&T offers broader bundle options, including pairing fiber internet with AT&T wireless plans for combined discounts that Quantum Fiber does not match.
- AT&T Fiber's higher-tier multi-gig plans and brand recognition, plus extensive retail and support presence, can make it a more familiar, one-stop choice for some households.

How to switch to Quantum Fiber
Switching to Quantum Fiber is straightforward. Start by using a referral link from a current customer (the site owner may earn a referral reward too), then check whether your exact address is serviceable at quantumfiber.com, since availability is street-by-street across roughly 17 states. If fiber is available, choose a plan, place your order, and either self-install with the included SmartNID and 360 WiFi gateway in about 10 to 15 minutes or schedule a technician visit. Once your service is active, keep it running for 60 consecutive days; after Aklamio audits the referral, both you and the friend who referred you can each receive up to $100 in cash via PayPal or bank deposit, with full payout taking up to about 90 days. You must be a new residential customer at a fiber-available address to qualify.
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.
