How Quantum Fiber Compares
Here is Quantum Fiber's 1 Gig plan next to other gig-tier plans we track, using each provider's own listed price. These providers don't all serve the same streets, so treat it as a price reference rather than a head-to-head at your address.
| Provider | Gig plan | Listed price | Price conditions | Checked |
|---|---|---|---|---|
| Quantum Fiber | 1 Gig (up to 940 Mbps) | $50/mo | $25 new-customer discount + $5 bank AutoPay discount; $80 standard | Nov 7, 2026 |
| Xfinity | 1 Gig | $60/mo | 5-year price guarantee; new customers; AutoPay from bank and paperless billing | Nov 6, 2026 |
| Google Fiber | Core 1 Gig | $70/mo | No promotional pricing; plus taxes and local access fee | Nov 6, 2026 |
| T-Mobile Fiber | Fiber 1 Gig | $55/mo | With AutoPay, includes a limited-time $5/mo discount; $70 standard | Nov 6, 2026 |
Quantum Fiber has the lowest listed gig price of the four, but it's also the one with no published end date on its discount and a rate that jumps to $80 if you stop paying by bank account. Xfinity's price comes with a five-year guarantee, and Google Fiber's $70 has no promo at all. In parts of Quantum Fiber's footprint, CenturyLink still sells DSL on the old copper lines; where both reach your address, Quantum Fiber's plans list much higher speeds. See our fiber internet guide for how fiber compares with cable and 5G home internet.
