Quantum Fiber 3 Gig (2026)

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

Quantum Fiber 3 Gig is a high-end, multi-gigabit fiber-to-the-home plan, part of the lineup now branded Quantum Fiber from AT&T after AT&T acquired the consumer fiber business in early 2026 (the network and plans are unchanged). It sits near the top of the tier ladder, above the entry, 500 Mbps, 1 Gig, and 2 Gig options, with an up-to-8 Gig tier available only in select areas. Like all the plans, it comes with no annual contract, no early-termination fee, and no data caps.

What it is

Best for

Large or busy households where many people stream 4K, game, and video-call at the same time without anyone noticing the difference
Heavy uploaders: creators, photographers, and remote workers pushing big files to the cloud, where the multi-gig headroom matters most
Smart homes with dozens of connected devices, plus a wired desktop or NAS that can actually take advantage of multi-gig speeds
Anyone who wants long-term future-proofing and rarely wants to think about bandwidth again

The detail

Be honest with yourself about whether 3 Gig will feel different from 1 Gig in daily use: most single devices, Wi-Fi connections, and even typical streaming or gaming sessions can't saturate a gigabit, let alone three. The 3 Gig tier shines when speed is spread across many simultaneous users and devices, or when you have wired gear (a desktop, server, or NAS) with multi-gig Ethernet to plug into. One footnote worth knowing: Quantum Fiber advertises symmetrical speeds (matching download and upload) specifically on its 500 Mbps and 1 Gig plans, and the 2 Gig-and-above tiers, including 3 Gig, are excluded from that symmetrical claim, so confirm the exact upload figure for your address before deciding. Every plan includes 360 WiFi, a Wi-Fi 7 gateway plus mesh pods where needed, and self-install (SmartNID plus the gateway, roughly 10-15 minutes) is offered in many markets; otherwise a technician comes out. Pricing is promotional and varies, with the multi-gig tiers landing well above the roughly $75 indicative price of 1 Gig, so always check your exact address on quantumfiber.com, since availability is street-by-street across about 17 states.

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).
