Research internet service in Houston ZIP code 77027, where AT&T fiber, Xfinity cable and fixed-wireless services create a competitive broadband market across Greenway/Upper Kirby and Afton Oaks/River Oaks.
ZIP-level research identifies the broadband options worth investigating. Your complete service address determines what can actually be ordered.
77027 is not a uniform residential service area. The ZIP combines established single-family neighborhoods, apartment communities, commercial corridors and the River Oaks District. Broadband availability therefore needs to be interpreted at both the ZIP and property levels.
FCC-derived ZIP data reports fiber availability across about 93.5% of 77027, with AT&T identified as the dominant fiber provider. Reported AT&T fiber speeds reach up to 5 Gbps in the ZIP, but the available tier still depends on the individual address.
Current FCC-derived data reports Xfinity cable coverage at roughly 99.77% of 77027. Reported maximum cable speeds reach 2 Gbps at some locations, while upload performance can vary substantially by network and service tier.
The table separates ZIP-level evidence from address-level serviceability. A provider shown below is an option to investigate, not a guarantee that every 77027 property can order it.
| Provider | Technology | 77027 evidence | Reported maximum | Verify |
|---|---|---|---|---|
|
AT&T Strong ZIP evidence |
Fiber / fixed internet | Fiber is reported across about 93.5% of the ZIP, with AT&T identified as the principal fiber provider. | Up to 5 Gbps fiber | |
|
Xfinity Strong ZIP evidence |
Cable | FCC-derived data reports approximately 99.77% cable availability from Xfinity across 77027. | Up to 2 Gbps | |
|
T-Mobile Home Internet Fixed wireless |
5G fixed wireless | FCC-derived data reports T-Mobile Home Internet across most of 77027, with availability determined by service address and network capacity. | Up to about 100 Mbps in ZIP-level FCC-derived data | |
|
Verizon 5G Home Internet Address dependent |
5G fixed wireless | Verizon 5G Home Internet is a Houston-market option and address-level records identify service in portions of 77027. | Up to 1 Gbps in some local records | |
|
EarthLink Retail option |
Fiber / DSL / fixed wireless | ZIP-level records identify EarthLink services using multiple underlying technologies. EarthLink should be evaluated as a retail provider rather than automatically treated as a separate physical network. | Up to 5 Gbps where fiber is available | Underlying network, technology, exact address, speed, price and installation terms. |
|
Satellite providers Alternative |
Satellite | Satellite is available as a separate broadband technology, but the dense wired-network environment in 77027 means it should be evaluated after checking terrestrial options. | Provider dependent | Current plan, latency, equipment, installation, data policies and total monthly cost. |
The most useful finding is not simply the number of providers. It is the combination of a broad cable footprint, extensive fiber reporting and several fixed-wireless alternatives.
FCC-derived data reports fiber as available to about 93.51% of 77027 and indicates fiber is the fastest connection type for roughly 82.13% of locations in the dataset. AT&T is the principal fiber network behind that pattern.
Xfinity cable is reported at approximately 99.77% availability. That makes cable particularly important when an address does not qualify for the desired AT&T fiber tier, or when a household is comparing wired plans by price and equipment rather than maximum upload performance.
T-Mobile and Verizon fixed-wireless services appear in local broadband records. Their practical value depends on address eligibility and network capacity, so a strong ZIP-level wireless percentage should not be interpreted as a guaranteed speed at a particular home.
Greenway includes multiple apartment properties, while the ZIP also contains established single-family neighborhoods. A provider that reaches a nearby detached home may not have identical installation arrangements inside a multifamily building.
These figures describe the reported ZIP-level market and should be used as a research starting point rather than an ordering guarantee.
The connection type matters because advertised download speed alone does not describe the full service.
Fiber is the dominant high-capacity technology in the ZIP-level data. AT&T currently advertises fiber service in the River Oaks area with speeds up to 5 Gbps where available. Fiber also generally provides much stronger upload capability than conventional cable. The specific fiber tier must be checked at the address.
Xfinity's cable network has a very broad 77027 footprint. Current ZIP-level records report up to 2 Gbps download at some locations. Upload capability is more variable than fiber, so households doing large cloud backups, frequent video uploads or other upload-heavy work should compare the actual upload figure shown for the address.
T-Mobile Home Internet uses a fixed wireless gateway connected to the cellular network rather than a dedicated wired line to the home. Local FCC-derived records show substantial 77027 coverage, but eligibility and performance depend on the service location and available network capacity.
Verizon is another fixed-wireless option worth checking at an eligible 77027 address. Local records show Verizon fixed wireless service in the ZIP, but the exact service tier and eligibility should be confirmed directly because cellular home-internet capacity can differ between nearby locations.
Houston's official ZIP records identify several recognizable local areas within 77027. They are useful for understanding the physical setting, but they are not substitutes for an address-level provider check.
Houston's 77027 records identify the Greenway / Upper Kirby area. The area contains apartment communities and commercial corridors alongside residential properties. For renters, building wiring, existing provider arrangements and installation access can affect the practical broadband choices.
Afton Oaks / River Oaks is another major local reference associated with 77027. Afton Oaks housing records show a substantial single-family component, including 438 single-family properties in the cited 2025 neighborhood dataset. A detached-home service result should not automatically be applied to nearby apartments or condominium buildings.
River Oaks District at 4444 Westheimer Road has multiple 2026 renovation projects registered with the Texas Department of Licensing and Regulation. This is commercial rather than residential broadband evidence, but it illustrates why individual buildings and developments in 77027 should be checked separately rather than treating the ZIP as a single uniform network footprint.
The ZIP's physical development pattern is relevant because broadband availability can be determined at the building or service-location level.
Current property records identify multiple apartment communities along Cummins Street and nearby Greenway streets. Residents should ask management whether the building has preferred providers, existing wiring, bulk-service arrangements or installation restrictions.
Afton Oaks contains a significant established single-family housing stock. At these addresses, the key question is normally whether the provider's network reaches the specific lot and which technology the provider's address checker assigns to it.
Ongoing tenant renovations at River Oaks District demonstrate that 77027 includes substantial commercial and mixed-use development. Business connectivity should not be inferred from residential availability records, and residential availability should not be inferred from business fiber records.
Houston's official 77027 map places the ZIP beside 77005, 77007, 77019, 77024, 77046, 77056, 77081 and 77098. A property only a short distance across one of these boundaries can therefore require a separate broadband lookup.
ZIP-level broadband data is useful for identifying the networks worth checking. The complete property address is the final serviceability test.
Include the apartment, condominium or unit number when applicable.
Compare the reported providers, technologies and advertised speeds associated with the location.
Use each provider's own address checker to determine what can currently be ordered.
Review regular pricing, promotional terms, equipment, installation, taxes and fees.
Apartment and condominium residents should ask management about bulk service, wiring and installation rules.
The ZIP has an unusually strong overlap between fiber and cable networks. That means the question is often not simply whether broadband exists, but which network reaches a particular building or lot. A single-family property can have a different technology mix from an apartment building a few blocks away. Provider records should therefore be treated as location-specific evidence rather than a ZIP-wide guarantee.
These ZIP codes appear around 77027 on the City of Houston's official ZIP map. Each should be researched separately because postal boundaries do not necessarily follow broadband network boundaries.
Start with AT&T Fiber and Xfinity for the main wired comparison, then check T-Mobile or Verizon fixed wireless if those options are relevant to the address. Apartment and condominium residents should also confirm building-level service arrangements.
This page separates ZIP-level broadband evidence, provider information, local geographic records and address-level serviceability rather than treating them as interchangeable.
These answers distinguish documented ZIP-level broadband patterns from actual serviceability at an individual Houston property.
