Broadband in 77048 is a relatively competitive Houston market with substantial fiber and cable coverage alongside fixed-wireless options. Current ZIP-level records identify AT&T fiber, Xfinity cable, EarthLink, T-Mobile 5G Home Internet and Verizon as significant residential broadband choices. The local network picture is not uniform: older South Acres, Crestmont Park, Sunnyside and Minnetex-area housing sits alongside newer subdivisions and recently built homes.

The current 77048 data point to a stronger wired market than a simple cable-only Houston ZIP. Xfinity has an extensive cable footprint, while AT&T and EarthLink are associated with substantial fiber coverage. T-Mobile also reports a large fixed-wireless footprint in the ZIP, with Verizon providing another wireless alternative.
Current FCC-derived ZIP data report AT&T fiber availability across approximately 83.8% of 77048. AT&T's Houston service information currently advertises fiber speeds up to 5 Gbps where available. The percentage is a ZIP-level estimate, not a guarantee for an individual address.
Current ZIP-level data report approximately 99.3% Xfinity cable availability in 77048. The same data identify a smaller Xfinity fiber footprint. That makes Xfinity the dominant cable network in the dataset, but the technology reaching a particular property still needs to be verified.
Current ZIP-level records report approximately 98.5% T-Mobile fixed wireless availability and about 59% Verizon fixed-wireless availability. Those figures make wireless worth checking independently rather than treating it only as a fallback when wired service is unavailable.
The table distinguishes provider evidence reported for the ZIP from address-level ordering information. FCC-derived availability data are useful for mapping the local market, but location-level verification is necessary before treating a provider, technology or speed as available at a particular property.

The provider descriptions below focus on networks with meaningful current evidence in ZIP 77048. Coverage figures are presented as dataset findings, not as guarantees that every residence can order the listed service.
AT&T is one of the most important broadband networks to investigate in 77048 because current ZIP-level data identify a substantial fiber footprint. One current FCC-derived dataset estimates AT&T fiber availability at approximately 83.8% of the ZIP, with maximum reported fiber speeds reaching 5 Gbps.
Xfinity has the broadest wired footprint reported in the current 77048 dataset. Approximately 99.3% cable availability is reported, with a smaller fiber footprint of about 17.7%. The distinction is useful because the Xfinity brand does not necessarily describe the same underlying technology at every address.
EarthLink is significant in 77048 because current ZIP-level records associate it with a substantial fiber footprint. The same dataset reports EarthLink fiber availability at approximately 83.8%, with maximum fiber speeds of 5 Gbps. EarthLink should be evaluated as a service provider rather than assumed to operate a completely separate physical network from the infrastructure underlying its availability.
T-Mobile is unusually important to the 77048 comparison because the current ZIP-level data report approximately 98.5% fixed-wireless availability. That makes T-Mobile a meaningful alternative to wired service in the ZIP rather than merely a backup for locations without cable or fiber.
Verizon provides another fixed-wireless option in 77048, although its reported footprint is substantially smaller than the current T-Mobile estimate. One current ZIP-level dataset reports approximately 59% Verizon fixed-wireless availability, with a maximum reported speed of 300 Mbps.
Satellite service remains geographically available in 77048 and operates independently of the local fiber and cable plant. It is therefore relevant when a specific property has fewer terrestrial options, although the performance characteristics differ substantially from fiber and cable.
The current 77048 market includes multi-gig fiber, high-capacity cable and fixed wireless. The most useful comparison depends on the technology available at the property, not simply the largest advertised download number.
Suitable for ordinary browsing, video calls, streaming and moderate household use when the connection is stable.
Useful for households with several simultaneous users, multiple streaming devices and larger downloads.
Relevant for larger households, frequent large downloads and homes with many active devices when the local network supports the tier.
AT&T and EarthLink are associated with 5 Gbps maximum fiber service in current 77048 ZIP-level records, where the address and underlying network support the tier.
The ZIP contains a mix of established postwar housing, newer subdivisions and other residential development. That combination makes the distinction between fiber, cable and fixed wireless particularly relevant when comparing the actual choices available at a property.
AT&T and EarthLink have substantial fiber footprints in current 77048 data, while a smaller Xfinity fiber footprint is also reported. Fiber availability is therefore a major part of the ZIP's broadband market rather than a limited niche.
Xfinity is the principal cable network identified in current ZIP-level data, with approximately 99.3% cable availability reported. Cable can provide high download capacity, but upload performance should be compared separately with fiber.
T-Mobile and Verizon provide wireless alternatives that do not require a dedicated cable or fiber drop. The current data report extensive T-Mobile coverage and a smaller but significant Verizon footprint.
Satellite remains geographically available throughout 77048 regardless of local fiber or cable construction. It can provide an additional option where terrestrial choices are limited, but latency and equipment requirements differ materially from wired broadband.
ZIP 77048 covers a south Houston area that includes the South Acres / Crestmont Park, Sunnyside and Minnetex portions of the city, along with a mixture of older residential subdivisions and newer housing developments. That development history helps explain why a ZIP-wide provider percentage should not be treated as a property-level result.
Current data show substantial Xfinity cable availability alongside large AT&T and EarthLink fiber footprints. This gives many addresses more than one high-capacity wired technology to investigate. The actual competitive set still depends on the individual property.
A current FCC-derived dataset estimates AT&T fiber availability at approximately 83.8% of 77048. AT&T's Houston service information separately confirms fiber service in Houston with speeds up to 5 Gbps where available. The two pieces of evidence support treating fiber as a central local option rather than assuming AT&T is primarily a legacy copper provider in this ZIP.
Current ZIP-level records estimate approximately 99.3% Xfinity cable availability in 77048. That makes Xfinity the broadest reported wired network in the dataset, even though it is not the only wired technology available. A household with AT&T fiber should compare the two technologies at the address rather than assuming cable is the only practical wired choice.
T-Mobile's reported fixed-wireless footprint covers approximately 98.5% of the ZIP in the current dataset, while Verizon is reported at approximately 59%. These figures make 5G home internet worth checking even where cable or fiber appears available. Wireless eligibility remains dependent on the service address and network capacity.
Current local housing records identify established communities such as Waverly Gardens, Crestmont Park, Minnetex Place and King Estates, while also showing newer developments including Southridge Crossing, El Tesoro, Park Vista at El Tesoro, Daybreak, South Meadow Place and Villas at Almeda Springs. Different construction periods can mean different internal wiring, conduit and provider infrastructure.
South Acres and Crestmont Park contain substantial postwar housing, while nearby newer subdivisions contain homes built much more recently. A broadband provider list derived from one property should therefore not automatically be applied to another part of the ZIP. This is particularly relevant when comparing fiber construction, existing coaxial plant and fixed-wireless service.
The following findings describe what the current evidence means for residents rather than simply listing provider names.
| Finding | Evidence | What it means for a 77048 address |
|---|---|---|
| AT&T fiber | Current ZIP-level data report approximately 83.8% AT&T fiber availability | AT&T should be checked as a major fiber provider rather than treated only as a legacy copper network. |
| EarthLink fiber | Current ZIP-level data report approximately 83.8% EarthLink fiber availability | EarthLink is a significant fiber option in the ZIP, but the actual underlying network and plan should be verified at the address. |
| Xfinity cable | Current ZIP-level data report approximately 99.3% Xfinity cable availability | Xfinity is the broadest reported wired network in the ZIP and is relevant to most address-level comparisons. |
| Xfinity fiber | Current ZIP-level data report a smaller 17.7% Xfinity fiber footprint | The Xfinity brand should not automatically be interpreted as cable at every address. |
| T-Mobile Home Internet | Current ZIP-level data report approximately 98.5% fixed-wireless availability | 5G Home Internet is a meaningful local alternative, although exact eligibility depends on capacity and address. |
| Verizon 5G | Current ZIP-level data report approximately 59% fixed-wireless availability | Verizon is worth checking separately from T-Mobile because the reported footprints are different. |
| Older housing | South Acres, Crestmont Park, Waverly Gardens and Minnetex include substantial older housing stock | Existing coaxial infrastructure, property wiring and neighborhood plant can differ from newer developments. |
| Newer development | Local records identify newer subdivisions such as El Tesoro, Southridge Crossing and Park Vista at El Tesoro | Newer construction can have different conduit, fiber and internal wiring arrangements from older streets. |
These locations are useful reference points for understanding the geography and housing mix of the ZIP. They are not substitutes for an address-level broadband check.
Neighboring ZIP codes can have different network footprints. Use them as separate research areas rather than transferring 77048 availability assumptions across ZIP boundaries.
The correct sequence is to use ZIP-level research to identify the relevant network choices, then verify the exact property with each provider before comparing plans.
FCC-derived datasets are useful for understanding which providers and technologies are reported in 77048. The FCC National Broadband Map provides location-level information, including providers, technologies and reported speeds at a searched location. Provider address checkers remain the appropriate source for live ordering eligibility, current plans and current pricing.
The local network mix makes it useful to compare technology and property-level availability before focusing on the largest advertised download number.
AT&T and EarthLink fiber can provide much higher upload capacity than a conventional cable connection where the fiber service is available. This can matter for cloud backups, remote work, large file transfers, cameras and other upload-heavy activity.
Xfinity cable is reported across approximately 99.3% of 77048 in the current ZIP-level dataset, while a smaller Xfinity fiber footprint is also reported. The exact address determines which technology and plan can actually be ordered.
T-Mobile and Verizon should be checked separately from cable and fiber. Wireless service can be simpler to install at some properties, but capacity, signal conditions and network load can produce a different performance profile from a dedicated wired connection.
ZIP-level research identifies the local market. Provider address tools determine what can actually be ordered at the property.
