Internet Providers With Data Caps (2026): Who Still Limits Your Data, and What It Costs

For most U.S. households, the internet bill is no longer just about speed. It is also about how much data you are allowed to use. A data cap is a monthly limit on the data a home internet plan includes, measured in gigabytes (GB) or terabytes (TB). Every video stream, cloud backup, game download, and video call counts toward it.

The landscape has shifted quickly. A few years ago, caps were standard on cable internet. In 2026, fiber providers, Spectrum, and the major 5G home carriers sell unlimited data, and some of the best-known cap enforcers have loosened or dropped their limits. But caps have not disappeared. BroadbandNow's provider database listed 92 providers with data caps as of September 24, 2026. Household usage keeps climbing, so a cap that seemed generous in 2021 is easier to hit today.

This guide explains which internet providers still have data caps, how those caps work, what happens when you exceed them, how much data households actually use, and how to avoid overage fees. It is written as consumer research, not a sales pitch, and it flags places where sources disagree.

Which internet providers still have data caps in 2026?

Providers that still apply caps to at least some plans include Xfinity (legacy plans, 1.2 TB), Cox (1.25 TB on wired plans, though Cox markets are now moving to Spectrum), AT&T (non-fiber Internet plans at 1.5 TB and fixed wireless at 350 GB), HughesNet (100–200 GB of priority data), Viasat (soft caps that vary by plan), Sparklight (as low as 700 GB), Buckeye (as low as 250 GB), and some Mediacom, EarthLink and Starlink plans. Fiber networks such as AT&T Fiber, Verizon Fios, Google Fiber, Frontier Fiber, and Quantum Fiber, along with Spectrum and Optimum, generally include unlimited data.

Key Findings

Caps are shrinking but not gone. Xfinity's newest plans include unlimited data, and Charter says former Cox markets now have access to Spectrum's no-cap packaging as of mid-September 2026.

Technology predicts the cap. Fiber rarely has one. Limits concentrate on older copper, DSL, fixed wireless, and satellite connections.

Overage fees follow a pattern. Many wired providers charge about $10 per extra 50 GB, usually with a monthly maximum of around $100.

Usage keeps growing. OpenVault reported average household usage of about 767 GB per month in Q4 2025, and roughly one in four households used 1 TB or more.

"Unlimited" can still have fine print. Satellite and fixed wireless plans may slow speeds after a threshold instead of billing overages.

Policies depend on plan and location. Two neighbors on the same provider can have different data rules if they are on different plans.

Provider-by-Provider Breakdown

Xfinity (Comcast)

Xfinity's own support pages say its latest internet plans include unlimited data. A 1.2 TB limit remains on older, "legacy" plans. Customers on legacy plans get alerts as they approach the limit, and Xfinity's FAQ describes a courtesy policy where the first overage in 12 months is not charged, although the company notes that policy is subject to change.

Third-party guides published earlier in 2026 describe overages of $10 per 50 GB, up to $100 a month, and an optional unlimited add-on. Some of those guides still describe the cap as applying to "most" Xfinity plans, which conflicts with Xfinity's current language. The most likely explanation is timing: those guides describe the older structure. If you are an Xfinity customer, sign in to your account to see which category your plan falls into.

Cox and the Charter Merger

Cox has been the most prominent cable holdout. One September 2026 analysis reports a 1.25 TB monthly allowance on every wired Cox plan, with $10 charged per 50 GB and a $100 monthly maximum.

That is changing. Charter completed its acquisition of Cox on August 20, 2026, and Charter states that as of mid-September, customers in former Cox markets have access to Spectrum's products and pricing, including internet with no data caps. The FCC's approval reportedly included a commitment letting Cox customers keep their existing plans, so an existing Cox customer may still be on a capped plan until they switch. If you are a current or prospective Cox customer, ask specifically whether your plan or a Spectrum plan applies at your address.

AT&T

AT&T's cap depends on the technology reaching your home.

AT&T Fiber includes unlimited data.

AT&T Internet delivered over older copper or hybrid infrastructure has a 1.5 TB allowance on plans up to roughly 100 Mbps.

AT&T fixed wireless has a much lower 350 GB allowance, and one review notes overage charges can reach $200 a month.

The practical takeaway: if fiber is available at your address, it removes the data question entirely. Readers can also see our related guide, Does AT&T Home Internet Have a Data Cap?, for a deeper look at AT&T's tiers.

Regional Cable Providers: Mediacom, Sparklight, Buckeye

Regional cable providers are where caps are most varied. Mediacom has largely removed caps from its Xtream packages, but older or lower tiers may still be limited, and some sources cite allowances up to 3 TB. Sparklight and Buckeye can be far stricter: allowances as low as 700 GB (Sparklight) and 250 GB (Buckeye) appear on some plans, while other plans from the same companies are unlimited. Always check the specific plan's terms.

Satellite Internet: HughesNet, Viasat and Starlink

Satellite is where "unlimited" most often has an asterisk.

HughesNet plans include 100–200 GB of "priority" data. After that, reviewers report speeds falling to roughly 1–3 Mbps for the rest of the billing cycle, which makes video streaming impractical. HughesNet also offers a late-night "Bonus Zone" allowance.

Viasat uses soft caps rather than hard limits. Its Unleashed plan is described as having an 850 GB threshold beyond which speeds may be reduced during congestion. Other Viasat plans carry smaller priority allowances, reported anywhere from 40 GB to 300 GB depending on the plan.

Starlink residential service is generally described as unlimited standard data. Some budget plans limit roaming data (reported as 50 GB) or use deprioritized data.

Fixed Wireless: T-Mobile and Verizon 5G Home

The major 5G home internet products do not enforce hard caps, but they reserve the right to deprioritize heavy users when the network is busy. In practice, that means speeds can dip at peak times for very high-usage households. Coverage is address-specific, so availability checks matter.

Consumer Impact: How Much Data Do You Actually Need?

Use household size and habits, not just speed, to estimate need.

These are illustrative ranges based on the averages and distributions reported by OpenVault, not measurements for any specific home.

How to Check Your Own Usage

Log in to your provider's app or online account and look for a data usage meter.

Review at least three months of history, since usage swings with seasons and events.

Check your router's traffic statistics if your provider does not display usage.

Note whether your provider counts uploads (cloud backups and video calls count on most plans).

How to Avoid Data Cap Overages

Switch to an unlimited plan from the same provider if one is offered.

Choose fiber where available.

Move large downloads to off-peak hours if your provider has a bonus window (HughesNet offers one).

Adjust streaming quality for devices that don't need 4K.

Turn on usage alerts so you are warned before you cross the threshold.

Compare the add-on price against the price of a competing unlimited plan.

Frequently Asked Questions

Which internet providers have data caps?

Providers with caps on at least some plans include Xfinity (legacy plans, 1.2 TB), Cox (1.25 TB, transitioning to Spectrum), AT&T's non-fiber plans (1.5 TB) and fixed wireless (350 GB), HughesNet, Viasat, Sparklight, Buckeye, and some Mediacom and EarthLink plans. Caps vary by plan and location, so confirm the terms for your address.

Does Xfinity still have a data cap?

Xfinity says its newest internet plans include unlimited data. A 1.2 TB monthly cap still applies to older legacy plans, where overages may be charged after a courtesy allowance. Third-party guides sometimes describe the cap as universal, so sign in to your Xfinity account to confirm which plan you have.

Does Cox have a data cap?

Cox has enforced a 1.25 TB monthly cap on its wired plans, with overages of $10 per 50 GB up to $100 a month. After Charter completed its acquisition on August 20, 2026, Spectrum's no-cap products became available in former Cox markets from mid-September. Existing customers may still be on legacy plans.

Does fiber internet have data caps?

Generally no. AT&T Fiber, Verizon Fios, Google Fiber, Frontier Fiber, and Quantum Fiber are reported as unlimited. Fiber networks have high capacity, so caps are rare. Provider terms can change, so review the plan details before you sign up.

What happens if I go over my data cap?

It depends on the provider. Cable and DSL providers typically bill overages, often $10 per extra 50 GB with a monthly maximum around $100. Satellite and fixed wireless providers usually reduce your speed instead. Some providers waive the first overage or offer a courtesy month.

How much data does the average household use?

OpenVault reported average household usage of roughly 767 GB per month in Q4 2025, with a median near 532 GB and about one in four households using 1 TB or more. A mid-2026 reading put the average around 711 GB. Averages are rising each year.

Is 1 TB of data enough for a family?

For many households, yes, but not for all. The median home uses well below 1 TB, but families with several 4K streams, gaming, remote work, and cloud backups can approach or pass it. If you regularly use more than 700–800 GB, look for an unlimited plan.

Is satellite internet really unlimited?

Not always. HughesNet gives 100–200 GB of priority data, then slows speeds sharply. Viasat uses soft caps that reduce priority after a threshold. Starlink residential is generally unlimited for standard data. Check the "priority data" and "deprioritization" terms in the plan details.

Can I get an internet plan without a data cap?

Usually yes, depending on your address. Options include fiber, Spectrum, Optimum, Astound, and 5G home internet where covered. Enter your address on each provider's site or call (855) 210-8883 to ask about availability where you live.

Conclusion

Data caps are no longer the default, but they have not vanished. Fiber, Spectrum, Optimum, and the 5G home carriers have largely moved to unlimited plans, and Xfinity and Cox customers are seeing the biggest changes of the year. Caps persist mainly on legacy cable plans, older AT&T copper and fixed wireless services, satellite, and some regional providers.

Because usage keeps rising, the safest approach is to check your current plan, review three months of usage, and compare it with the terms of any provider you are considering. If your household is near the limit, an unlimited plan often costs less than repeated overages.
