Houston ZIP 77033

77033 Internet Providers

Broadband in 77033 is unusually strong on the wired side of the market: current ZIP-level records identify AT&T fiber and Xfinity cable across most or nearly all of the ZIP, while Verizon and T-Mobile add fixed-wireless alternatives. The ZIP includes established South Park and Sunnyside-area housing alongside newer infill, so the provider list for a specific property still needs to be verified at the address level.

● This guide separates ZIP-level network evidence from address-level ordering results. A provider appearing in 77033 data does not mean every house, apartment or newly built property can order every technology.

What the 77033 broadband evidence shows

The current evidence does not describe 77033 as a cable-only or fiber-only market. Secondary FCC-derived ZIP records report AT&T fiber at about 97.76% of the ZIP and Xfinity cable at 100%, while fixed-wireless records show T-Mobile and Verizon as additional choices. The exact percentages vary by dataset and reporting vintage, so they are used here to describe the market rather than to promise service to an individual home.

Fiber

AT&T fiber is the key wired alternative

Current FCC-derived ZIP research reports AT&T fiber across about 97.76% of 77033, with a ZIP-level maximum around 5 Gbps. Current property-level records also show AT&T fiber at multiple 77033 addresses. The exact address remains the deciding test.

Cable

Xfinity has the broad cable footprint

Current ZIP-level records report Xfinity cable at 100% of 77033 in one FCC-derived dataset, with maximum reported cable speeds reaching 2 Gbps. That makes Xfinity an important comparison even at addresses where AT&T fiber is also reported.

77033 provider comparison

This table combines current provider information with ZIP-level research. Coverage percentages are dataset estimates, not household-level guarantees. Provider availability tools remain the final check for service, technology, speed and current pricing.

Provider	Technology	77033 evidence	Advertised maximum	Verify
AT&T Fiber Major ZIP footprint	Fiber	FCC-derived ZIP research reports AT&T fiber at approximately 97.76% of 77033. Current 77033 property records also show fiber service reaching individual addresses.	Up to 5 Gbps where available	Check AT&T
Xfinity ZIP-wide cable evidence	Cable	Current ZIP-level FCC-derived data report Xfinity cable across 100% of 77033 in the cited dataset. Individual plans can still differ by address.	Up to 2 Gbps in applicable locations	Check Xfinity
T-Mobile 5G Home Internet Broad wireless evidence	5G fixed wireless	Current ZIP-level records report T-Mobile fixed-wireless coverage across about 98.44% of 77033 in the cited dataset. Eligibility remains address and capacity dependent.	Plan and location dependent	Check T-Mobile
Verizon 5G Home Internet Substantial wireless footprint	Fixed wireless	Current ZIP-level records report Verizon fixed-wireless coverage across about 61.52% of 77033 in the cited dataset. Verizon also states that Houston has 5G Home Internet, with address-level eligibility determining the actual result.	Up to 1 Gbps where available	Check Verizon
AT&T Internet Air Wireless alternative	Fixed wireless	AT&T is reported in 77033 data for both wired and fixed-wireless service. Internet Air should be treated as a separate technology from AT&T Fiber when comparing a particular address.	Up to 300 Mbps in current Houston offerings	Check AT&T
EarthLink Resold / dataset-listed	Fiber, DSL and fixed wireless depending on location	FCC-derived ZIP datasets list EarthLink alongside AT&T for fiber, DSL and fixed-wireless records. The underlying network should be identified before comparing EarthLink with facilities-based providers.	Network and location dependent	Check the exact address and underlying technology
Satellite providers Broad geographic option	Satellite	Satellite networks are geographically relevant throughout 77033 because they do not depend on the local fiber or cable plant. They are included as an alternative technology, not as evidence of a preferred connection.	Provider and plan dependent	Check equipment, latency and current plan terms

77033 interpretation: The strongest local finding is the coexistence of a very broad Xfinity cable footprint and a very broad AT&T fiber footprint in current FCC-derived data. That creates a materially different comparison from ZIPs where only one major wired network is present. Wireless options add another layer, but their eligibility is not equivalent to a wired footprint.

Internet providers serving the 77033 market

Provider descriptions below emphasize evidence that is specific to 77033. Where a dataset identifies a broad footprint, the percentage is labeled as a dataset estimate rather than treated as a guarantee.

AT&T Fiber

Fiber ~97.76% in cited ZIP dataset Up to 5 Gbps

AT&T is the most significant fiber finding in the available 77033 data. A current FCC-derived dataset reports AT&T fiber availability at approximately 97.76% of the ZIP, with a maximum advertised download speed around 5,000 Mbps. Recent property records for 77033 also show AT&T fiber at individual addresses, providing address-level evidence that the ZIP-wide fiber result is not merely a citywide claim.

Fiber is the principal AT&T wired technology reported for 77033.
AT&T's current Houston information advertises fiber tiers up to 5 Gbps where available.
Upload performance can differ substantially from cable, so upload capacity should be compared separately.

Local evidence: The 77033 fiber dataset reports approximately 97.76% AT&T fiber coverage. Current 77033 property records independently show AT&T 5,000/5,000 Mbps fiber at multiple listed addresses. These examples establish local availability but do not prove every address qualifies.

Xfinity

Cable 100% in cited ZIP dataset Up to 2 Gbps

Xfinity is the other major wired network in the 77033 comparison. A current FCC-derived ZIP dataset reports cable availability at 100% of the ZIP and maximum cable speeds up to 2,000 Mbps. This makes Xfinity especially important because its reported footprint overlaps the broad AT&T fiber footprint rather than simply filling a gap where fiber is absent.

The cited ZIP dataset reports Xfinity cable throughout 77033.
Current 77033 property records show Xfinity cable alongside AT&T fiber at specific homes.
Cable upload performance should not be inferred from the 2 Gbps download maximum.

Local evidence: FCC-derived 77033 records report 100% Xfinity cable availability and an average maximum cable speed of about 1,697 Mbps in that dataset, with local maximum tiers reaching 2 Gbps.

T-Mobile 5G Home Internet

5G fixed wireless ~98.44% in cited ZIP dataset Capacity dependent

T-Mobile is a meaningful wireless alternative in 77033. Current ZIP-level records report fixed-wireless availability at approximately 98.44% in the cited dataset. That broad geographic result should not be read as guaranteed ordering eligibility: T-Mobile's own home internet process requires an address check, and wireless capacity can differ between nearby locations.

The network reaches 77033 broadly in the cited FCC-derived data.
Wireless performance depends on signal, congestion and local network conditions.
T-Mobile's live address checker is the correct test for current eligibility and plan terms.

Local evidence: The current 77033 provider dataset lists T-Mobile Home Internet at approximately 98.44% availability, with an average maximum speed around 47 Mbps in that older FCC-derived dataset. Current T-Mobile plan capabilities can differ from that historical filing, so the live provider result should control the plan comparison.

Verizon 5G Home Internet

Fixed wireless ~61.52% in cited ZIP dataset Address dependent

Verizon provides another fixed-wireless layer in 77033. The cited ZIP-level data report Verizon fixed-wireless availability across approximately 61.52% of the ZIP, with a reported average maximum speed of about 346 Mbps in that dataset. Verizon's current Houston information confirms 5G Home Internet service is offered in Houston, while its coverage guidance explains that address-specific factors determine eligibility.

Verizon's local footprint is materially narrower in the cited ZIP data than Xfinity or AT&T fiber.
5G Home availability can differ between neighboring properties.
Building materials, signal conditions and network capacity can affect the final result.

Local evidence: The 77033 fixed-wireless dataset reports Verizon at approximately 61.52% availability. Verizon separately states that Houston has 5G Home Internet and that eligibility is determined at the home address.

AT&T Internet Air

Fixed wireless Separate from fiber Address dependent

AT&T appears in 77033 records under more than one technology. That distinction matters. A property can be associated with AT&T in ZIP-level data without the service being AT&T Fiber; fixed wireless and older copper/DSL records also appear in the local data. Current AT&T offerings include Internet Air as a wireless option where fiber is not available.

Do not treat every AT&T record in 77033 as proof of fiber.
AT&T's availability tool identifies the actual technology at the address.
Fiber should be compared separately from Internet Air or older copper service.

Evidence standard: The 77033 dataset reports AT&T fixed wireless and DSL in addition to fiber. This is why the provider comparison identifies technology rather than simply listing AT&T as one undifferentiated service.

EarthLink

Multiple technologies Dataset-listed Verify underlying network

EarthLink appears in current ZIP-level datasets alongside AT&T for fiber, DSL and fixed-wireless records. Because EarthLink can market service over underlying network infrastructure rather than operating the same facilities in every location, the useful question for a 77033 address is which technology and network actually supports the offered plan.

Fiber and fixed-wireless records are both associated with EarthLink in the cited data.
The underlying network matters when comparing upload capacity and service characteristics.
Current plan availability should be checked at the exact address.

Evidence standard: EarthLink is included because it appears in the current 77033 provider dataset. It is not presented as a separate physical network equivalent to AT&T or Xfinity without address-level verification.

Satellite providers

Satellite Broad geographic option Different network model

Satellite service is geographically available in 77033 and remains relevant as a backup or alternative technology. It does not depend on the neighborhood fiber or cable plant, but latency, equipment, weather sensitivity and plan characteristics differ from wired broadband.

Satellite does not require a local cable or fiber line to the home.
Performance should be compared using latency and upload capacity as well as download speed.
Where AT&T fiber or Xfinity cable is available, satellite is a materially different connection type.

Evidence standard: Satellite is included as a geographically broad technology category, not as a claim that it is the best or most appropriate connection for a particular 77033 property.

77033 internet speed guide

The ZIP has enough fiber and cable capacity that the practical comparison is not simply whether a home can get broadband. At many properties, the meaningful choice is between fiber and cable, with 5G fixed wireless as another option. Upload capacity becomes especially important when two wired networks are available.

100–300

Mbps

Suitable for ordinary browsing, video calls, streaming and moderate household use when the connection is stable.

500 Mbps

Mbps

Useful for several simultaneous users, multiple streaming devices and larger downloads without requiring a multi-gig tier.

1–2 Gbps

High-capacity plans

Relevant to larger households and heavy downloads where the local AT&T or Xfinity network supports the tier.

5 Gbps

AT&T fiber

AT&T currently advertises fiber speeds up to 5 Gbps in Houston where available; 77033 data show a broad fiber footprint.

Do not compare download speed alone. At a 77033 address where AT&T Fiber and Xfinity both appear, upload capacity, latency, equipment, installation, pricing and the actual technology reaching the property can matter more than the difference between two headline download numbers.

Connection types in 77033

The local network picture is shaped by the coexistence of a mature residential street grid, established mid-century housing and newer infill. Those physical differences can affect how the same ZIP-level provider list translates to a particular property.

Fiber

AT&T fiber is the dominant fiber finding in the cited 77033 data, reported at about 97.76% of the ZIP. Current property records also show 5 Gbps symmetrical AT&T fiber at multiple 77033 addresses.

Cable

Xfinity cable is reported throughout 77033 in the cited dataset, with local maximum tiers reaching 2 Gbps. Cable remains a direct competitor to the broad AT&T fiber footprint.

5G / fixed wireless

T-Mobile and Verizon both appear in 77033 fixed-wireless records. Wireless service can be useful where a household wants an alternative to wired installation, but eligibility and performance are address and capacity dependent.

Satellite

Satellite networks are available across the ZIP as a separate infrastructure model. They can serve properties outside a provider's terrestrial footprint but usually have different latency and upload characteristics from fiber or cable.

What is different about broadband in 77033?

Several local findings are more useful than a generic provider list because they explain why two 77033 addresses can produce different results even inside the same ZIP.

77033 has broad fiber and broad cable at the same time

The cited FCC-derived data report AT&T fiber at about 97.76% of the ZIP and Xfinity cable at 100%. That is a significant local finding: many residents are not choosing between fiber and a fallback connection, but potentially between two major wired networks. Exact address verification is still required.

Current 77033 property records show the wired overlap in practice

Recent 77033 property records list AT&T fiber at 5,000/5,000 Mbps together with Xfinity cable at up to 2,000/250 Mbps at individual addresses. These examples are not a ZIP-wide coverage estimate, but they provide direct local evidence that fiber-versus-cable is a real comparison in 77033.

The housing stock is predominantly established rather than uniformly new

City and housing sources describe South Park as a series of tract-home subdivisions developed largely in the 1950s, while current ZIP housing records show many subdivisions with average build years from the 1940s through the 1960s. Newer infill also exists. This mix makes building condition and property-specific wiring more relevant than a single ZIP-wide assumption.

Sunnyside and South Park do not represent one uniform local network

Houston's own neighborhood records identify South Park as a distinct super neighborhood, while city planning records show Sunnyside and South Park spanning different ZIP boundaries. ZIP 77033 is therefore better treated as a service-market boundary than as a single neighborhood with one infrastructure pattern.

Wireless coverage is broad, but it is not equivalent to wireline coverage

The cited ZIP dataset reports T-Mobile fixed wireless at about 98.44% and Verizon at about 61.52%. Those numbers identify a meaningful wireless market, but 5G Home eligibility can change between nearby addresses because cellular capacity and signal conditions are not mapped the same way as a fixed cable or fiber plant.

New infill can sit inside an older street network

Housing records for 77033 show older subdivisions such as South Park, Sunnyside Gardens and Inwood Terrace alongside newer properties and subdivisions such as Bayou Estates and Contemporary South. A newer building can therefore have different internal wiring or service arrangements from an older neighboring house even when both share the same ZIP code.

77033 local broadband findings

These findings translate the provider data into practical conclusions without treating ZIP-level percentages as exact-address service maps.

Finding	Evidence	What it means for a 77033 address
AT&T fiber	About 97.76% in the cited ZIP-level FCC-derived dataset; up to 5 Gbps reported	AT&T should be checked as a primary fiber option rather than treated only as a legacy copper provider.
Xfinity cable	100% cable availability in the cited 77033 dataset; up to 2 Gbps locally reported	Xfinity is a major wired competitor across the ZIP and may overlap with AT&T fiber.
AT&T fiber + Xfinity at one property	Recent 77033 property records list 5,000/5,000 AT&T fiber and 2,000/250 Xfinity cable	At least some 77033 homes can make a direct fiber-versus-cable comparison; this should not be generalized to every address.
T-Mobile Home Internet	About 98.44% fixed-wireless availability in the cited ZIP dataset	T-Mobile is a substantial local alternative, but live eligibility and capacity should be checked.
Verizon 5G Home	About 61.52% fixed-wireless availability in the cited ZIP dataset	Verizon is relevant but has a narrower reported ZIP footprint than AT&T fiber or Xfinity cable.
Older housing stock	South Park was largely developed in the 1950s; many 77033 subdivisions have mid-century average build years	Property-level wiring and the physical condition of the residence can affect installation details even where the street network is present.
Newer infill	ZIP housing records also identify newer developments and homes	New construction can have different conduit, internal wiring or building arrangements from older nearby homes.

Areas and development patterns inside 77033

These are useful geographic reference points for the ZIP. They are not substitutes for an address-level broadband check, and provider footprints can cross neighborhood boundaries differently from ZIP boundaries.

South Park Houston officially recognizes South Park as Super Neighborhood 72. The city describes the area as a series of tract-home subdivisions developed along South Park Boulevard in the 1950s, with multiple parks in ZIP 77033. The established housing pattern makes property-level service verification useful.

Sunnyside Sunnyside forms a major part of the local residential context, but Houston planning records show that the super neighborhood crosses multiple ZIP codes. A 77033 provider result should therefore not be transferred automatically to Sunnyside addresses in other ZIPs.

Sunnyside Gardens Current housing records identify Sunnyside Gardens as one of the largest named subdivision areas in 77033, with an average build year in the late 1940s in the cited dataset. Older housing can make internal wiring and installation conditions more relevant.

Inwood Terrace Inwood Terrace is another substantial 77033 subdivision. Current housing data place much of its housing stock in the mid-1950s, reinforcing that the ZIP contains established residential infrastructure rather than a uniform new-build environment.

Bayou Estates Bayou Estates appears among the newer housing areas in current 77033 subdivision records, with a cited average build year around 2003. Newer development can have different internal wiring from nearby mid-century subdivisions.

Crestmont / South Crest Crestmont and South Crest are established residential areas identified in 77033 housing and city records. Their presence illustrates why a ZIP-level provider list should be interpreted as a market overview, not as a statement that every residential block has identical infrastructure.

Why this matters: 77033 combines older tract-home neighborhoods with newer infill and multiple housing types. The broad AT&T fiber and Xfinity footprints make the ZIP look highly connected at the market level, but the exact serviceable technology still belongs to the individual property.

How to verify internet service at a 77033 address

The broad ZIP-level picture is useful for narrowing the choices. The final comparison should be performed at the property.

1. Wired networks

Check AT&T Fiber and Xfinity separately

Because both have broad reported footprints in 77033, check both address tools rather than assuming one is unavailable because the other is present. Confirm the actual technology, maximum tier and installation requirements.

2. Wireless

Check T-Mobile and Verizon separately

A broad wireless footprint does not guarantee an offer at a particular address. Network capacity, radio conditions and the provider's eligibility system can produce different results between nearby homes.

3. Property type

Check whether the address is a house or multifamily property

Apartment and other multifamily properties can have building-specific wiring, provider agreements or equipment arrangements. The provider list for a nearby single-family property is not a reliable substitute.

4. ZIP data

Use coverage percentages as a research layer

ZIP-level data help establish that a provider is materially present in 77033. They should not be converted into claims that a specific house or apartment can order the service.

What to compare before choosing a 77033 connection

In a ZIP with broad fiber and cable footprints, the useful comparison is about the actual service delivered to the property, not just the provider's headline maximum.

Fiber versus cable

Check upload capacity

Current 77033 property records show AT&T fiber with symmetrical 5 Gbps capability alongside Xfinity cable with lower reported upload capacity. Upload performance can matter for remote work, cloud backups, large file transfers and content creation.

Address overlap

Check which wired networks reach the property

The ZIP-level data suggest that many 77033 properties have both major wired networks nearby. The live address result determines whether that overlap actually exists at the property.

Established housing

Check building-level infrastructure

Mid-century housing is common in parts of 77033, while newer infill also exists. Installation paths, internal wiring and equipment can differ between older homes, remodeled properties and newer construction.

Check the exact 77033 address

ZIP-level research identifies the local market. Provider address tools determine which services can actually be ordered at the property.

Check Availability

Sources and methodology

Provider-specific claims are weighted toward official provider information. ZIP-level network comparisons use current secondary datasets derived from FCC Broadband Data Collection records, with limitations stated where the underlying dataset is older than the current provider pages.

Official provider sources

AT&T's current Houston home-internet and fiber pages were used for current Houston availability guidance and advertised fiber capabilities up to 5 Gbps where available.
AT&T's current address-availability guidance was used to distinguish ZIP or city service-area information from exact-address eligibility.
Verizon's Houston home-internet information was used to confirm that 5G Home Internet is offered in Houston and that availability depends on the home address.
T-Mobile's current Home Internet eligibility page was used for the requirement to check a specific address rather than infer eligibility from broad wireless coverage.
Xfinity and other provider address tools should be treated as the final source for current property-level service, technology, plan and pricing.

FCC and ZIP-level broadband data

FCC Broadband Data Collection-derived ZIP records were reviewed for 77033 provider technologies and estimated availability footprints.
One current 77033 dataset reports AT&T fiber at 97.76% and Xfinity cable at 100%, with T-Mobile fixed wireless at 98.44% and Verizon fixed wireless at 61.52%.
The cited detailed ZIP dataset states that its underlying data were based on FCC availability information as of December 31, 2024; those percentages are therefore treated as a historical coverage layer rather than a live ordering result.
A separate current provider index and recent 77033 property records were used as cross-checks for the continuing presence of AT&T fiber, Xfinity cable and fixed-wireless alternatives.
The FCC explains that its National Broadband Map supports address searches that show the providers, technologies and speeds reported for an individual location. That location-level approach is the appropriate final verification method.

77033 internet provider FAQ

Answers below are limited to what the current local evidence can support.

What internet providers serve ZIP code 77033?

Current ZIP-level broadband records identify AT&T fiber, Xfinity cable, T-Mobile fixed wireless and Verizon fixed wireless as major options in 77033. AT&T also appears in fixed-wireless and older DSL records, while EarthLink is listed across multiple technologies. Satellite services are a geographically broad alternative.

Is AT&T Fiber available in 77033?

Current FCC-derived ZIP research reports AT&T fiber across about 97.76% of 77033 in the cited dataset, and recent 77033 property records show AT&T 5 Gbps symmetrical fiber at individual addresses. Availability must still be confirmed at the exact address.

Does Xfinity serve 77033?

Yes. The cited 77033 cable dataset reports Xfinity cable throughout the ZIP, with local maximum download speeds reaching 2 Gbps. The address-level Xfinity result should be used to confirm the current plan and upload characteristics.

Can a 77033 home have both AT&T Fiber and Xfinity?

Yes, at least some 77033 properties have both. Recent property records show addresses with AT&T fiber at 5,000/5,000 Mbps and Xfinity cable at up to 2,000/250 Mbps. That is evidence of local overlap, not a guarantee that both networks reach every address.

Is T-Mobile 5G Home Internet available in 77033?

Current ZIP-level records report T-Mobile fixed-wireless coverage across about 98.44% of 77033 in the cited dataset. T-Mobile's current process requires an address check, and the service can vary with network capacity and local wireless conditions.

Is Verizon 5G Home Internet available in 77033?

Current ZIP-level records report Verizon fixed-wireless coverage across about 61.52% of 77033 in the cited dataset. Verizon confirms 5G Home Internet availability in Houston, but its own coverage guidance states that eligibility is determined at the home address.

Does AT&T in 77033 always mean fiber?

No. The 77033 data contain AT&T fiber, fixed-wireless and DSL records. A household should check the actual technology returned by AT&T's address tool rather than infer fiber availability from the provider name alone.

Why does housing age matter when checking 77033 internet?

Much of the ZIP's housing stock dates from the mid-20th century, while newer infill and subdivisions also exist. The provider network outside a property can be broad while internal wiring, installation paths or building arrangements differ. This is particularly relevant for older homes, remodeled properties and multifamily buildings.

Can two nearby homes in 77033 have different internet options?

Yes. Wired infrastructure can differ by street, property or building, and fixed-wireless eligibility can change with network capacity and signal conditions. A nearby address is useful context but is not a substitute for checking the actual service address.

Why does this page use ZIP-level data instead of claiming exact coverage?

ZIP-level data are useful for identifying the broadband market around 77033, but provider networks do not follow ZIP boundaries perfectly. The FCC's National Broadband Map supports location-level searches because service, technology and speed can differ from one address or building to another.

Availability disclaimer: Provider names, technologies, advertised speeds, pricing and availability can change. ZIP-level broadband information does not guarantee service at an individual address. Apartment buildings, subdivisions and individual properties may have different network infrastructure. Some ZIP-level percentages cited on this page come from FCC-derived datasets with older reporting dates and are used as research evidence, not as live ordering results. Always confirm service, technology, speed, equipment requirements and current pricing directly with the provider before ordering.
