Quantum Fiber 500 Mbps (2026)

Reviewed by the Quantum Fiber Code team● Referral verified June 1, 2026Re-verified on the 1st of every month.

Quantum Fiber 500 Mbps is the entry mid-tier on Quantum Fiber's fiber-to-the-home network (now branded Quantum Fiber from AT&T), delivering roughly 500 Mbps both ways. It is one of the two plans Quantum Fiber markets as fully symmetrical, meaning your upload speed matches your download speed rather than the lopsided uploads typical of cable. Indicative pricing sits around $50 a month, though promotions vary by market and time.

What it is

Best for

Households of two to four people who stream, browse, and video call across several devices at once without buffering
Remote workers and students who upload large files, back up to the cloud, or join HD meetings and need the matching upload speed symmetrical fiber provides
Cost-conscious homes that want true fiber reliability and no data caps without paying for gigabit-plus tiers they will not use
Anyone who tried cable internet and was frustrated by slow uploads, since the symmetrical 500 Mbps fixes that imbalance

The detail

The 500 Mbps tier hits a practical sweet spot: 500 Mbps down is plenty for simultaneous 4K streams, large game downloads, and a houseful of connected devices, while the equal 500 Mbps up is where it pulls ahead of cable at a similar price. That symmetry matters for uploading video, backing up photos, running a home NAS, or hosting clean two-way calls where your outbound feed stays crisp. Like every Quantum Fiber plan it comes with no annual contract, no early-termination fee, and no data caps, and the 360 WiFi Wi-Fi 7 gateway is included (with mesh pods added where a larger home needs them). Self-install is available in many markets in about 10 to 15 minutes using the SmartNID and 360 WiFi; otherwise a technician handles setup. If you later outgrow 500 Mbps, you can move up to 1 Gig (also symmetrical) or higher 2 Gig and up tiers, which are not covered by the symmetrical claim. One caveat that applies to every tier: availability is street-by-street across roughly 17 states, so the only way to know if 500 Mbps is offered at your home is to check your exact address 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.
