Quick Answer: Fios vs Xfinity
Verizon Fios wins for speed reliability, symmetrical uploads, and customer satisfaction. Xfinity wins for broader availability, more plan options, and bundling flexibility. Fios uses fiber-optic technology delivering consistent speeds with no data caps, while Xfinity uses cable (HFC) with a 1.2 TB monthly data cap on most plans. If both are available at your address, Fios is the better overall choice for most households.
Verizon Fios vs Xfinity: Head-to-Head Comparison
Choosing between Verizon Fios and Xfinity is one of the most common decisions for internet shoppers in the northeastern United States. Both providers serve millions of customers, but they use fundamentally different technologies and pricing strategies. This in-depth comparison breaks down every factor that matters.
Technology: Fiber vs Cable
The most significant difference between these two providers is the underlying infrastructure. Verizon Fios uses a 100% fiber-optic network (FTTH - Fiber to the Home), while Xfinity uses a hybrid fiber-coaxial (HFC) cable network.
Fiber-optic (Fios) transmits data as pulses of light through glass strands, delivering symmetrical upload and download speeds with extremely low latency. Fiber is less susceptible to electromagnetic interference, weather conditions, and distance-related signal degradation. Fios customers consistently receive speeds at or above their advertised plan speeds.
Cable (Xfinity) uses coaxial cable for the last mile to your home, sharing bandwidth among neighborhood nodes. During peak usage hours (typically 7-11 PM), cable speeds can slow as more users in your area consume bandwidth. Upload speeds on cable are significantly slower than downloads, typically 5-35 Mbps depending on the plan.

Speed Performance
Verizon Fios consistently delivers speeds at or above advertised rates. In Ookla Speedtest data, Fios ranks among the top three fastest ISPs nationwide. The symmetrical upload speeds are a massive advantage for video conferencing, cloud backup, content creation, and smart home devices that upload data continuously.
Xfinity delivers competitive download speeds but falls behind significantly on uploads. The 10-35 Mbps upload on most Xfinity plans is a notable limitation for remote workers and creators. During evening peak hours, some Xfinity users report speed reductions of 10-30% as neighborhood bandwidth becomes congested.
Data Caps
Verizon Fios: No data caps on any plan. Unlimited usage is included at no extra cost.
Xfinity: Most plans include a 1.2 TB monthly data cap. Exceeding this cap costs $10 per 50 GB block, up to a maximum of $100/month in overage charges. You can remove the cap by adding the Unlimited Data option for $30/month or by upgrading to a Gigabit-tier plan in some markets where caps have been removed.
For context, 1.2 TB handles most households comfortably. However, families with multiple 4K streamers, heavy gamers, or remote workers uploading large files may exceed this limit. The average US household uses around 500-600 GB per month, but power users can easily surpass 1.2 TB.
Equipment and Installation
Fios: Includes a router at no extra charge with all plans. The Fios Router (Wi-Fi 6E) comes standard with Gigabit and higher plans. Installation is free for online orders and typically takes 2-4 hours for new fiber installations. A technician visit is required for new Fios installations since an ONT must be mounted on your home.
Xfinity: Charges $14/month for the xFi Gateway modem-router combo. Self-installation kits are available for $15 (one-time). Professional installation costs $100. You can use your own modem to avoid the rental fee (see our Best Modem-Router Combos Guide).
Customer Satisfaction
Verizon Fios consistently ranks higher than Xfinity in customer satisfaction surveys. In the 2025 ACSI (American Customer Satisfaction Index), Fios scored 73/100 compared to Xfinity's 63/100. J.D. Power's 2025 Residential Internet Service Provider Satisfaction Study placed Fios in the top three nationally, while Xfinity ranked in the bottom half.
Key satisfaction drivers for Fios include speed consistency, transparent pricing with no hidden fees, and a straightforward cancellation process with no early termination fees. Xfinity's lower scores stem from pricing complexity, data cap frustrations, and aggressive promotional-to-standard pricing jumps after the first year.
Availability
Verizon Fios is available in parts of 9 states plus Washington, D.C.: Connecticut, Delaware, Maryland, Massachusetts, New Jersey, New York, Pennsylvania, Rhode Island, and Virginia. Even within these states, coverage is not universal. Fios availability is concentrated in suburban and urban areas.
Xfinity is available in 40+ states, covering roughly 58 million homes. It has significantly broader geographic reach than Fios. In many areas, Xfinity is the only high-speed broadband option available.
Bundling Options
Both providers offer TV and phone bundles. Fios offers Fios TV (traditional cable), YouTube TV partnerships, and a digital phone option. Xfinity offers X1 TV, Flex streaming device, and Xfinity Mobile (cellular service). Xfinity's mobile service is a standout perk, offering Verizon-network coverage at reduced prices for internet customers.
Who Should Choose Fios?
- Remote workers who need fast, reliable upload speeds
- Heavy data users who want no data caps
- Gamers seeking low-latency connections
- Households with multiple 4K streamers
- Customers who value price transparency and consistent speeds
Who Should Choose Xfinity?
- Customers in areas where Fios is not available

- Users whose monthly data usage stays under 1.2 TB
- Customers who prefer self-installation flexibility
The Verdict
If both Verizon Fios and Xfinity are available at your address, Fios is the better choice for most users. The symmetrical fiber speeds, no data caps, included router, and higher customer satisfaction scores make it the more reliable and straightforward option. Xfinity is a strong alternative when Fios is unavailable, and its lower-tier plans offer good value for light internet users on a budget.

Frequently Asked Questions
Is Verizon Fios faster than Xfinity?
Yes, in real-world performance. While both offer gigabit download speeds, Fios provides symmetrical upload speeds (1 Gbps up and down) versus Xfinity's 20-35 Mbps upload on comparable plans. Fios also delivers more consistent speeds during peak usage hours due to its dedicated fiber connection.
Does Xfinity have data caps?
Yes. Most Xfinity plans include a 1.2 TB monthly data cap. Exceeding this cap incurs overage charges of $10 per 50 GB, up to $100/month maximum. You can add unlimited data for $30/month. Verizon Fios has no data caps on any plan.
Can I get Verizon Fios and Xfinity at the same address?
In many parts of the northeastern US, yes. Both providers serve overlapping areas in states like New York, New Jersey, Pennsylvania, Connecticut, and Massachusetts. Use both providers' availability checkers to confirm service at your specific address.
Which is cheaper, Fios or Xfinity?
Xfinity's entry-level plan ($19.99/mo for 75 Mbps) is cheaper than Fios' lowest tier ($49.99/mo for 300 Mbps). However, at the gigabit level, Fios ($89.99/mo with included router and no data cap) and Xfinity ($75/mo plus $14/mo gateway rental plus potential $30/mo for unlimited data = up to $119/mo) are comparable or favor Fios when factoring in total costs.
Is fiber better than cable internet?
Generally yes. Fiber offers symmetrical speeds, lower latency, no shared bandwidth, and greater reliability. Cable is more widely available and can deliver fast download speeds at lower entry-level prices. For power users, gamers, and remote workers, fiber is the superior technology.
Can I keep my email address if I switch from Xfinity to Fios?
Xfinity allows you to retain your @comcast.net email address for 90 days after cancellation. After that, it may be permanently deleted. We recommend migrating to a provider-independent email service like Gmail or Outlook before switching to avoid losing access.
Do I need a contract for Fios or Xfinity?
Neither provider requires contracts for internet-only plans in 2026. Both have moved to month-to-month pricing. However, Xfinity promotional pricing may change after 12-24 months, while Fios prices have been more stable without drastic increases after the promotional period.
