Katy, Texas broadband guide

Katy Internet Providers

Katy has a competitive broadband market built around multiple fiber networks, a broad Xfinity cable footprint, smaller Spectrum and Astound footprints, and fixed-wireless alternatives from T-Mobile, Verizon and AT&T. Fidium and Ezee Fiber have added particularly strong multi-gig fiber competition in parts of the Katy market.

Start with your address

A ZIP code helps identify the broader Katy market, but the complete service address is the reliable way to determine which provider, technology, speed and plan can actually be ordered.

Fiber Several fiber networks compete in the Katy market
8 Gbps Multi-gig symmetrical fiber is reported in parts of Katy
2 Gbps Current Xfinity maximum reported in the local market
Address-level Final availability requires a service-address check
Quick answer

What internet providers serve Katy?

Katy is a multi-network broadband market. The provider mix changes substantially between individual developments, streets and properties, particularly where newer fiber construction overlaps older cable infrastructure.

The providers worth checking first in Katy are Fidium Fiber, Ezee Fiber, AT&T Fiber and Xfinity. Spectrum and Astound also appear in portions of the market, while T-Mobile, Verizon and AT&T Internet Air provide fixed-wireless alternatives. Satellite services remain available as a fallback.

This is a market-level provider list, not a claim that every provider serves every Katy home. FCC-derived data shows where providers report service within geographic locations, while the provider's own address checker determines whether a particular property can actually be ordered.

Fidium Fiber

Fidium has become one of the most significant fiber competitors in Katy. The company identifies Katy as a Texas market for its fiber service and introduced 5 Gig and up to 8 Gig symmetrical tiers there in 2026.

Ezee Fiber

Ezee Fiber is another multi-gig fiber network appearing in Katy broadband data. Current FCC-derived market information reports speeds reaching 8 Gbps in portions of the market.

AT&T Fiber

AT&T maintains a Katy-specific residential internet presence and advertises fiber speeds up to 5 Gbps where available. Its reported fiber footprint is more limited than Xfinity's cable footprint, so address verification matters.

Xfinity

Xfinity provides the broadest reported cable footprint in the current Katy market snapshot. Current local information lists residential tiers reaching up to 2 Gbps, with upload performance varying by plan and network technology.

Spectrum

Spectrum has a residential presence in Katy and currently advertises service up to 1 Gbps. Its footprint should be treated separately from Xfinity because cable availability varies by local network territory.

Astound Broadband

Astound appears in current Katy market data with both fiber and cable service reported in portions of the area. Its footprint is smaller than Xfinity's, making exact-address verification especially important.

Always use the provider's address checker before treating a listed plan as available to your home.

Local broadband story

Katy has become a multi-fiber market

The most significant change in Katy broadband is the growth of competing fiber networks alongside the area's established cable infrastructure.

Katy should not be treated as a simple cable-versus-fiber market.

Current FCC-derived market data identifies Fidium Fiber, Ezee Fiber, AT&T and Astound among the fiber networks appearing in the Katy market. Fidium's own 2026 announcements identify Katy as the first Texas market where it introduced new 5 Gig and up to 8 Gig symmetrical tiers.

Ezee Fiber also appears in current market data with symmetrical speeds reaching 8 Gbps in parts of Katy. AT&T advertises up to 5 Gbps where its fiber network reaches an address.

The practical question for a resident is therefore not simply whether fiber exists in Katy. It is which fiber networks reach the property, which tiers are actually offered, and how those plans compare with the available cable and wireless options.

Fidium Fiber

Major Katy fiber network · Up to 8 Gbps symmetrical

Fidium is one of the most consequential recent broadband developments in Katy. The company identifies Katy as one of its Texas fiber markets and announced new 5 Gig and up to 8 Gig symmetrical tiers there in April 2026.

Current FCC-derived market data also places Fidium among the more widely reported fiber networks in the Katy market. That combination of footprint and multi-gig tiers makes Fidium a provider worth checking before defaulting to cable.

The reported market footprint is not an address-level service guarantee. New developments, apartment buildings and individual streets can have different serviceability results.

Check Fidium Availability

Ezee Fiber

Multi-gig Katy fiber network · Up to 8 Gbps reported

Ezee Fiber is another important part of Katy's changing fiber market. Current broadband data reports Ezee with symmetrical speeds reaching 8 Gbps in portions of the area.

Ezee's significance is not simply its maximum speed. A smaller fiber network can materially change the choices available at the properties it reaches, especially where Xfinity or another cable provider was previously the main wired alternative.

Availability should be verified at the complete service address because network construction does not mean every nearby property is activated.

Check Ezee Availability

AT&T Fiber

Established fiber option · Up to 5 Gbps where available

AT&T has a dedicated Katy residential internet presence and currently advertises fiber service up to 5 Gbps where available.

Current FCC-derived market information shows AT&T fiber in a substantially smaller portion of the Katy market than Xfinity's reported cable footprint. That does not make the service unimportant; it means the exact address is particularly important when determining whether AT&T offers fiber or another form of internet service.

Check AT&T Availability

Astound Broadband

Smaller overlapping network · Fiber and cable reported

Astound appears in current Katy broadband data with both fiber and cable service reported in portions of the market.

Its presence matters most at addresses where it competes directly with another wired provider. The available technology should be confirmed because an Astound listing does not by itself establish that the address receives the same network technology or speed tier as another location.

Check Astound Availability
Cable internet

Xfinity remains a major wired option across Katy

Fiber expansion has changed the competitive picture, but cable remains important because Xfinity has the broadest reported cable footprint in current Katy market data.

Why Xfinity remains relevant

Current Katy broadband data reports Xfinity cable across essentially the full defined market area used in the provider snapshot. That gives cable a different role from smaller fiber networks that reach only portions of Katy.

Download capacity can be substantial

Xfinity currently lists Katy residential plans reaching 2 Gbps. That provides enough download capacity for many households, even where fiber is not available. Upload performance varies by plan and network technology.

Fiber's clearest advantage is usually upstream

When a household uploads large work files, maintains cloud backups, livestreams or regularly moves large project files, symmetrical fiber can provide a meaningful advantage over a cable connection with substantially lower upload capacity.

Compare the full price

Xfinity's current Katy pricing includes promotional and everyday rates. Compare the standard rate, equipment, installation, discounts and any price guarantee rather than evaluating only the initial advertised monthly price.

Check Xfinity Availability
Wireless options

5G home internet gives Katy households another alternative to wired service

T-Mobile and Verizon both provide fixed-wireless home internet options in the broader Katy market. AT&T also reports Internet Air availability in much of the market where its fiber network does not reach the property.

T-Mobile 5G Home Internet

Current Katy broadband data reports T-Mobile 5G Home Internet across the market, with plan speeds reaching roughly 498 Mbps download and 55 Mbps upload on current plan information. Actual performance depends on network conditions, signal quality and local capacity.

Check Availability

Verizon 5G Home Internet

Verizon's current 5G Home lineup includes tiers reaching up to 300 Mbps. Verizon states that actual availability and speeds vary by location and wireless conditions, so a Katy address check is required.

Check Availability

AT&T Internet Air

AT&T Internet Air is a fixed-wireless option that can matter at Katy addresses where AT&T Fiber is unavailable. Current market data reports speeds up to 100 Mbps down and 20 Mbps up in the local footprint.

Mobile coverage is not home eligibility

A strong 5G phone signal does not automatically mean the address qualifies for a home internet product. Fixed-wireless providers manage residential capacity by location, so the exact property must be checked.

Satellite

Satellite internet is mainly a fallback option in the Katy market

Starlink, Viasat and HughesNet provide additional residential connectivity, but satellite occupies a different position from Katy's growing fiber, cable and fixed-wireless networks.

For most Katy properties with usable fiber, cable or fixed-wireless service, satellite is unlikely to be the first technology to compare. Its primary value is reaching locations where terrestrial broadband is unavailable, unsuitable or difficult to activate.

Starlink uses low-Earth-orbit satellites and can provide a different speed and latency profile from traditional geostationary satellite services. Current plan pricing, equipment requirements and performance should be checked directly at the address.

HughesNet and Viasat remain additional satellite options. Their relevance is greater at properties outside practical wired broadband footprints, although satellite latency and plan policies should be considered before choosing them over a qualifying fiber, cable or fixed-wireless service.

Popular Katy ZIP codes

Major Katy ZIP codes used for local broadband research

Katy-area ZIP codes cover a much larger geography than the incorporated City of Katy alone. The principal mapped Katy ZIP codes include 77449, 77450, 77493 and 77494, while 77491 and 77492 are primarily post-office box ZIP codes. The broader Katy mailing area also crosses Harris, Fort Bend and Waller counties.

77449 North and northeast Katy area / Morton Ranch / western Harris County 77450 Cinco Ranch / Grand Lakes / established west Katy area 77493 North and northwest Katy / newer development corridors 77494 South and southwest Katy / Cinco Ranch / Fort Bend County

ZIP codes are useful for organizing broadband research, but they do not define provider territories. A single ZIP can contain multiple network footprints, and a Katy mailing address does not necessarily mean the property is inside the incorporated City of Katy.

Speed guide

How much internet speed does a Katy household need?

Katy residents can encounter plans from ordinary broadband tiers through 5–8 Gbps fiber. The highest advertised speed is not automatically the best value for a household.

100–300 Mbps

Often sufficient for a smaller household using web browsing, streaming, video calls, schoolwork and ordinary smart-home devices.

300–500 Mbps

A practical range for many households with several simultaneous users, remote work, streaming, gaming and connected devices.

500 Mbps–1 Gbps

Useful for larger households, frequent large downloads, multiple high-resolution streams and busy home networks.

1–3 Gbps

More useful when several users or wired devices can consume substantial bandwidth simultaneously or when large files are transferred regularly.

5–8 Gbps

Specialized multi-gig service. A household needs compatible networking equipment, Ethernet infrastructure and devices capable of using the additional capacity before these tiers provide their full practical benefit.

Don't overlook upload speed

Upload capacity matters for cloud backups, remote work, video production, livestreaming and other activities that send large amounts of data upstream.

Practical comparison

Fiber vs. cable in Katy

At addresses where both technologies are available, the decision usually comes down to upload performance, price, equipment, household usage and the actual plans offered at the property.

Factor Fiber Cable What it means locally
Download speed 1–8 Gbps where corresponding fiber tiers are available Up to 2 Gbps on current Xfinity market information Both can provide more than enough download capacity for many homes
Upload speed Often symmetrical on Fidium, Ezee and AT&T fiber tiers Usually lower than download speed on cable tiers Fiber has the clearer advantage for upload-heavy activities
Remote work Strong option when uploads and video calls matter Can work well for ordinary remote work Compare upload speeds rather than download speeds alone
Gaming Strong wired option where fiber is available Can also provide a good wired gaming connection Latency, routing and home networking matter in addition to bandwidth
Price Varies considerably by fiber network and address Promotional pricing can be competitive Compare standard rates and equipment, not only signup pricing
Availability Several overlapping networks, but individual footprints vary Xfinity has the broadest reported local cable footprint Exact-address verification remains essential
Katy-specific research

Katy's mailing area is larger than the incorporated city

One of the most important local details for broadband research is that a Katy mailing address does not necessarily mean a property is inside the City of Katy.

The City of Katy states directly that a Katy mailing address does not mean the property is within city limits. The broader Katy area extends across Harris, Fort Bend and Waller counties, while many residential communities commonly associated with Katy are outside the incorporated city.

This distinction matters for an internet guide because provider coverage data can be organized around different geographic definitions. A provider can have a large Katy-area footprint without serving every property inside the much smaller incorporated city, and a newer development can have a different provider mix from an older subdivision only a few miles away.

Older Katy and the original city area

Older residential areas around the historic Katy core can have a different broadband mix from newer master-planned communities farther west and south. Cable and legacy AT&T infrastructure can coexist with later fiber upgrades.

The age of a neighborhood should not be used as proof of which technology reaches an individual home.

Cinco Ranch

Cinco Ranch is a large established residential area in the broader Katy market. Current provider information shows that cable and fiber can overlap across the broader Katy area, but availability still varies by individual address.

A ZIP code or community name is useful for narrowing the search, not for confirming a particular provider.

Morton Ranch

Morton Ranch sits within the larger 77449 Katy-area market and includes established residential development. Xfinity's broad cable footprint makes cable a significant baseline, while fiber eligibility should be checked separately at the property.

Elyson and newer development

Newer master-planned development is particularly relevant to broadband research because network construction can be incorporated into new residential areas at a different stage from older neighborhoods.

A nearby fiber network or construction project should not be interpreted as proof that every lot, building or apartment is activated.

Cane Island

Cane Island is part of the broader Katy residential market. Homes in newer communities can have different provider choices from nearby established subdivisions, which makes address-level verification more useful than a citywide provider list.

Firethorne and west Katy

The west and southwest Katy development corridor includes large residential communities where fiber competition has expanded alongside existing cable infrastructure.

Provider availability should still be evaluated at the complete property address rather than assumed from nearby construction.

Seven Meadows and south Katy

Established south Katy communities can have a different network mix from newer construction farther west. The practical broadband comparison depends on which wired networks have reached the specific street and property.

Fort Bend County Katy

Some Katy mailing addresses are in Fort Bend County rather than the City of Katy or Harris County. County and municipal boundaries therefore should not be used as substitutes for provider address verification.

The City of Katy's own resident information emphasizes that mailing addresses and municipal boundaries are not interchangeable. This guide therefore treats "Katy" as the broader residential broadband market commonly associated with the Katy mailing area, while distinguishing it from the incorporated city where relevant.

Local market analysis

What the fiber competition means for Katy residents

Multiple fiber networks change the buying decision in Katy because a household may have more than one wired provider offering high upload speeds.

You may have more than one fiber choice

Some Katy properties can encounter Fidium, Ezee or AT&T fiber alongside cable service. When that happens, the comparison is no longer simply fiber versus cable.

Fidium changed the multi-gig market

Fidium introduced 5 Gig and up to 8 Gig symmetrical tiers in Katy in 2026. That gives qualifying addresses access to a level of upload capacity that previously would have been much less common in the local residential market.

Ezee adds another fiber alternative

Ezee Fiber's reported 8 Gbps symmetrical capability means that some Katy households may have a second multi-gig fiber network to compare rather than choosing between one fiber provider and cable.

Cable remains a major competitor

Xfinity's broad reported cable footprint means fiber providers do not operate in isolation. At many addresses, the practical decision is between a fiber offer and a cable offer with different upload speeds, pricing and equipment.

Use-case recommendations

Which internet connection makes sense for different Katy households?

There is no single provider that is appropriate for every Katy address. The recommendation changes with the networks available at the property and how the household uses its connection.

Best fit for remote work

Start with fiber if Fidium, Ezee or AT&T Fiber reaches the property. Prioritize upload speed, latency, equipment and service terms. A symmetrical 300 Mbps or 500 Mbps connection can be more useful for some remote workers than a cable plan with much faster downloads but substantially lower uploads.

Best fit for gaming

Prefer a wired fiber or cable connection when available. Compare latency, connection consistency, upload capacity and the quality of the home's Ethernet or Wi-Fi network instead of choosing solely by advertised download speed.

Best fit for families

A 300–500 Mbps plan may be enough for many families. Larger households with simultaneous streaming, gaming, cloud applications and large downloads may benefit from 500 Mbps to 1 Gbps. Multi-gig service is not automatically necessary.

Best fit for heavy upload users

Fiber deserves priority where available. Symmetrical upload capacity can make a noticeable difference for large cloud backups, video production, livestreaming and large project files.

Best fit for a renter or temporary resident

Compare no-contract fiber and cable options with 5G home internet. A wireless service can be attractive when installation simplicity matters, but eligibility must be confirmed before relying on it.

Best fit for a budget-conscious household

Compare the complete monthly cost rather than choosing the lowest advertised promotional price. Check the standard rate, equipment, installation, AutoPay requirements, discounts and any price guarantee.

Best fit for a new construction home

Check the exact address with every relevant provider. A fiber network shown nearby does not necessarily mean the line has been activated at every lot, building or apartment.

Best fit when wired service is unavailable

Check T-Mobile, Verizon and AT&T Internet Air first if the address qualifies. If fixed wireless is unsuitable or unavailable, satellite services provide another path to connectivity.

Address verification

How to check internet availability at a Katy address

Provider presence in Katy does not prove that a particular home can be connected. The complete service address is the most important part of the search.

Identify the exact property

Use the complete street address, including the apartment or unit number when applicable. Do not rely only on the ZIP code or subdivision name.

Check the FCC National Broadband Map

Use the FCC map as an independent location-level reference. The map allows consumers to search an address and review providers, technologies and reported speeds at that location.

Check each provider directly

Use the same complete address with Fidium, Ezee Fiber, AT&T, Xfinity, Spectrum, Astound, T-Mobile and Verizon as applicable. Provider tools can reflect service changes that are not obvious from a broad citywide listing.

Confirm the technology

Make sure the result actually identifies fiber, cable or fixed wireless. This distinction matters particularly with AT&T, which offers more than one residential access technology in the broader market.

Record upload and download speeds

Write down both numbers. Download speed alone does not show whether the service is well suited to remote work, cloud backups, livestreaming or other upload-heavy activities.

Compare the complete monthly cost

Check the promotional price, standard rate, equipment, installation, taxes, discounts, AutoPay requirements, contract and price guarantee before deciding.

Why this matters:

The FCC National Broadband Map is based on provider-submitted Broadband Data Collection information. The FCC explains that consumers can search an address to see reported providers, technologies and speeds, but the map is not a live ordering system. A provider's own address checker remains the final serviceability check before ordering.

Compare Katy Providers
Pricing

What should you actually compare when looking at Katy internet prices?

The lowest advertised monthly price is not necessarily the lowest-cost internet service over a full year.

Promotional rate

Check whether the displayed price applies only to new customers, requires AutoPay, requires a mobile bundle or lasts for a limited period.

Standard rate

Determine what the service costs after the promotional period. This is particularly important when comparing temporary introductory pricing with a longer-term price guarantee.

Equipment

Determine whether the gateway, router, Wi-Fi equipment or mesh hardware is included or charged separately.

Installation

Fiber installation can have different requirements from cable or 5G self-installation. Check whether professional installation is included.

Data policy

Check whether the plan includes unlimited data and whether any network-management or priority-data rules apply.

Price guarantee

A price guarantee can be more valuable than a temporary promotional discount. Verify the duration and exclusions rather than treating the guarantee as a permanent rate.

Moving to Katy

Moving to Katy? Check internet before you move in

Broadband should be treated as an address-specific utility when evaluating a home, apartment or new development.

A Katy mailing address can cover properties outside the incorporated City of Katy and across multiple counties. Provider availability can also differ between established subdivisions, newer master-planned communities, apartment buildings and individual streets.

Before signing a lease or closing on a property, check the exact service address with the providers that appear relevant. If dependable internet is important for remote work, school or home-based business use, do not rely solely on a statement that "fiber is available in Katy."

Research methodology

How this Katy internet guide was researched

This page is designed as a research resource rather than an independent speed-testing or customer-review page.

Last reviewed: October 4, 2026

Provider information: Current provider pages were reviewed for advertised speeds, plan characteristics, pricing examples, equipment and availability language. Provider claims are presented as provider-reported information rather than independent performance testing.

FCC information: FCC Broadband Data Collection information and current FCC-derived market datasets were used to understand reported provider footprints, technologies and maximum advertised speeds. The market data reviewed for Katy is based primarily on the December 2025 BDC vintage published in 2026, with subsequent revisions reflected in current datasets.

Local information: City of Katy information was used to establish the distinction between Katy mailing addresses and the incorporated city limits, as well as the broader Harris, Fort Bend and Waller County geography associated with Katy.

Fiber expansion evidence: Fidium's 2026 Katy announcements were reviewed because the company identified Katy as its first Texas market for new 5 Gig and up to 8 Gig symmetrical tiers. This is provider-reported network information and does not establish availability at every Katy address.

Editorial analysis: Statements about which connection may make sense for remote work, gaming, families, heavy upload use or other households are editorial interpretations based on the characteristics of the technologies and plans. They are not claims of independent performance testing.

FAQ

Frequently asked questions about internet in Katy

These answers focus on questions where current provider, FCC and local geographic evidence supports a useful answer.

Which internet providers are available in Katy?

The current Katy market includes Fidium Fiber, Ezee Fiber, AT&T Fiber, Xfinity, Spectrum and Astound among the principal wired providers appearing in current market data. T-Mobile and Verizon offer fixed-wireless home internet, while AT&T also offers Internet Air in parts of the market. Satellite providers provide additional alternatives. Exact availability depends on the address.

Does Katy have fiber internet?

Yes. Current Katy broadband data identifies several fiber networks, including Fidium Fiber, Ezee Fiber, AT&T and Astound in portions of the market. Fidium and Ezee are particularly significant because current market data reports multi-gig symmetrical tiers reaching 8 Gbps in parts of Katy.

Does Fidium Fiber serve Katy?

Yes. Fidium identifies Katy as one of its Texas fiber markets. In 2026, Fidium announced 5 Gig and up to 8 Gig symmetrical tiers in Katy, making the area an important market for the company's multi-gig fiber expansion. The exact service address must still be checked.

Does Ezee Fiber serve Katy?

Yes. Ezee Fiber appears in current FCC-derived Katy broadband data with fiber service reaching portions of the market and reported symmetrical speeds up to 8 Gbps. Its footprint is smaller than Xfinity's cable footprint, so availability is especially address dependent.

Is AT&T Fiber available in Katy?

Yes. AT&T maintains a Katy residential internet presence and advertises fiber speeds up to 5 Gbps where available. Current market data shows a more limited AT&T fiber footprint than Xfinity's cable footprint, so an address check is required.

Does AT&T offer non-fiber internet in Katy?

Yes. AT&T's broader Katy market includes Internet Air and other legacy service types. An address result that says AT&T Internet should not automatically be interpreted as AT&T Fiber. Confirm the technology shown for the actual property.

Is Xfinity available throughout Katy?

Xfinity has the broadest reported cable footprint in the current Katy market snapshot. Current local information also lists residential plans reaching up to 2 Gbps. Individual addresses should still be checked before ordering.

Does Spectrum serve Katy?

Yes. Spectrum maintains a residential internet presence in Katy and currently advertises plans reaching up to 1 Gbps. Availability should be checked at the complete service address because Spectrum and Xfinity operate different local network footprints.

Does Astound Broadband serve Katy?

Astound appears in current Katy market data with both fiber and cable service reported in portions of the market. Its footprint is smaller than Xfinity's, so the technology and speed available at a particular property should be confirmed directly.

Does Katy have 5G home internet?

Yes. T-Mobile and Verizon offer fixed-wireless home internet in the broader Katy market, while AT&T offers Internet Air. Eligibility depends on the service address and network capacity. Mobile phone coverage alone does not guarantee home internet eligibility.

What is the fastest advertised internet in Katy?

Current market data reports symmetrical speeds reaching 8 Gbps from Fidium and Ezee Fiber in portions of Katy. AT&T advertises fiber speeds up to 5 Gbps where available. These are maximum advertised capabilities, not guarantees that every Katy property can order those tiers.

Does Katy have 8 Gig internet?

Yes, 8 Gbps symmetrical fiber service is reported in portions of the Katy market. Fidium announced new 8 Gig service in Katy in 2026, and current FCC-derived market information also reports Ezee Fiber with up to 8 Gbps. Address-level verification is required.

Is fiber better than Xfinity cable?

Fiber generally has the clearest advantage in upload capacity and symmetrical performance. Xfinity can still provide substantial download capacity and has a much broader reported cable footprint. The better choice depends on the plans available at the address, upload requirements, price and equipment.

Is fiber worth paying more for remote work?

It can be, particularly for households that regularly upload large files, use cloud applications, participate in frequent video meetings or perform other upstream-heavy work. The key comparison is upload capacity rather than download speed alone.

Do I need gigabit or multi-gig internet?

Not necessarily. Many households can operate comfortably on less than 1 Gbps. Multi-gig service becomes more useful when several wired devices can consume high bandwidth simultaneously, large files move frequently or the home network has equipment capable of using the additional capacity.

Why can two nearby Katy homes have different internet providers?

Fiber networks have different construction footprints, and network upgrades can occur in stages. Apartment buildings, subdivisions, new developments, street-level construction and individual service records can all affect which providers can actually activate service.

Is Katy a city or a broader area?

Katy is an incorporated city, but the broader Katy mailing area is much larger than the city limits. The City of Katy states that a Katy mailing address does not necessarily mean the property is inside the incorporated city. The broader Katy area spans Harris, Fort Bend and Waller counties.

Which ZIP codes are associated with Katy?

The primary mapped Katy ZIP codes commonly used for local research include 77449, 77450, 77493 and 77494. ZIP codes 77491 and 77492 are primarily post-office box ZIP codes. ZIP boundaries should not be treated as provider network boundaries.

Does newer construction affect internet availability?

It can. Broadband networks are often built in phases, so a provider may have infrastructure nearby without every home or building being activated. New construction should always be checked using the exact service address.

What should I compare besides download speed?

Compare upload speed, technology, latency, equipment, installation charges, promotional and standard monthly prices, data policies, contracts, price guarantees and the provider's actual availability at the address.

What is the best way to check internet availability at my Katy home?

Start with the complete address. Use the FCC National Broadband Map for independent location-level context, then verify the result directly with the providers whose networks appear relevant. Provider address checkers should be treated as the final step before ordering.
