78228 has an unusually strong fiber component for a central San Antonio ZIP. Current secondary datasets based on FCC broadband records report AT&T Fiber at about 97% of the ZIP and Google Fiber at about 74.5%, while Spectrum cable is reported across roughly 99.7% of the ZIP. Those figures are useful for understanding the competitive structure, but they are still coverage estimates rather than live ordering results.
Current ZIP-level datasets report AT&T Fiber across most of 78228 and Google Fiber across a substantial portion of the ZIP. AT&T's own San Antonio service-area information specifically identifies 78228 with fiber service and lists speeds up to 5 Gbps where available. Google Fiber's current San Antonio offerings reach up to 8 Gbps.
Spectrum is reported as the dominant cable footprint in 78228, with current ZIP-level data estimating coverage at roughly 99.7%. This makes Spectrum relevant even where fiber is present because the street-level competition can differ from the ZIP-wide picture.
T-Mobile Home Internet and Verizon fixed wireless are also reported in 78228. Secondary FCC-derived datasets estimate broad wireless availability, but wireless eligibility is fundamentally different from a wired footprint because capacity, signal conditions and building characteristics affect individual addresses.
The table distinguishes ZIP-level coverage evidence from direct provider information. Percentages below are estimates from secondary datasets derived from FCC broadband records and should not be interpreted as proof that every address can order the listed service.
| Provider | Technology | 78228 evidence | Advertised maximum | What to verify |
|---|---|---|---|---|
|
AT&T Fiber
ZIP specifically identified
|
Fiber | AT&T's current San Antonio service-area information specifically lists 78228 with fiber service. Secondary FCC-derived ZIP datasets estimate fiber availability at about 97%. | Up to 5 Gbps where available | Exact address, fiber tier, installation requirements |
|
Google Fiber
Large ZIP footprint
|
Fiber | Current secondary FCC-derived datasets estimate Google Fiber availability at about 74.5% of 78228. The reported footprint is large enough that Google Fiber should be checked independently rather than treated as a niche provider. | Up to 8 Gbps in current offerings | Exact address and current serviceability |
|
Spectrum
Broad ZIP presence
|
Cable; limited fiber footprint | Current secondary ZIP-level datasets report Spectrum cable availability at roughly 99.7% of 78228. The figure represents reported coverage, not a guarantee for every building or unit. | Plan-dependent; up to multi-gig in selected areas | Residential plan, upload speed and exact technology |
|
T-Mobile 5G Home Internet
Fixed wireless
|
5G fixed wireless | Current ZIP-level FCC-derived datasets identify T-Mobile Home Internet in 78228. Wireless availability can change by address because T-Mobile manages service according to local capacity and radio conditions. | Plan-dependent; wireless speeds vary | Address eligibility, signal and network capacity |
|
Verizon 5G Home Internet
Fixed wireless
|
Fixed wireless | Current ZIP-level datasets report Verizon fixed wireless service in 78228. This identifies a local wireless alternative but does not establish that every address qualifies for Verizon 5G Home. | Plan and location dependent | Exact address and current 5G eligibility |
|
EarthLink
Uses multiple networks
|
Fiber / DSL / fixed wireless | Secondary ZIP-level datasets report EarthLink fiber and legacy DSL/fixed-wireless service in 78228. EarthLink should be evaluated by the underlying technology offered at the address rather than treated as a separate physical network in every case. | Up to 5 Gbps on applicable fiber service | Underlying network, technology, speed and price |
|
Smaller fixed-wireless providers
Limited footprints
|
Fixed wireless | ZIP-level datasets also report smaller fixed-wireless footprints, including VTX1 Companies and other local or regional networks. Their reported coverage is materially smaller than Spectrum, AT&T or the major fiber networks. | Provider and address dependent | Whether the individual property falls inside the footprint |
|
Satellite providers
Broad geographic option
|
Satellite | Satellite networks do not depend on the same neighborhood fiber, cable or terrestrial wireless plant. They remain geographically relevant even where 78228 has extensive wired infrastructure. | Provider and plan dependent | Latency, obstruction, equipment and plan terms |
The provider descriptions below focus on networks with meaningful reported coverage in 78228 and distinguish physical networks from resellers, legacy technologies and smaller footprints.
AT&T has one of the clearest current provider signals for 78228. AT&T's own San Antonio service-area information specifically lists ZIP 78228 with fiber service and advertises fiber speeds up to 5 Gbps where available. Secondary ZIP-level FCC-derived data estimates AT&T fiber coverage at approximately 97% of the ZIP.
Google Fiber is not merely a citywide possibility in 78228. Current secondary FCC-derived datasets estimate that roughly 74.5% of the ZIP has Google Fiber availability. The same datasets report multiple fiber speed tiers, with the highest advertised tier reaching 8 Gbps at eligible locations.
Spectrum remains a major wired provider in 78228 even though fiber competition is unusually substantial. Current ZIP-level datasets estimate Spectrum cable availability at approximately 99.7% of the ZIP. That makes Spectrum important when comparing actual choices at addresses where one or both fiber networks may not be available.
T-Mobile Home Internet adds a wireless option to a ZIP already served by extensive wired networks. Current ZIP-level datasets report T-Mobile fixed-wireless service in 78228. Unlike fiber and cable, however, the reported footprint cannot be interpreted as a simple street-level plant map because network capacity and radio conditions influence eligibility.
Verizon is another fixed-wireless option reported in 78228. Secondary broadband datasets identify a substantial Verizon fixed-wireless footprint in the ZIP, but a coverage estimate is not equivalent to Verizon's live 5G Home Internet eligibility system.
EarthLink appears prominently in 78228 broadband datasets, including fiber service that follows the underlying AT&T network footprint. Secondary data estimates EarthLink fiber coverage at approximately 97% of the ZIP. Because EarthLink can sell service over different technologies, the technology attached to the specific address matters more than the EarthLink brand name alone.
The ZIP's fiber competition makes upload speed particularly relevant. A 1 Gbps fiber connection and a 1 Gbps cable connection may have very different upload capacity, latency characteristics and network architecture. For 78228 households, technology should therefore be considered alongside the advertised download number.
Can cover ordinary browsing, video calls, streaming and lighter household use when the connection is stable and the household has relatively few simultaneous heavy users.
Useful for households with several simultaneous users, multiple streaming devices, cloud services and regular large downloads.
Relevant for large households, heavy downloads, substantial cloud activity and homes where several high-bandwidth devices operate at once.
Available only where the local fiber network and property support the tier. Multi-gig service also requires compatible Ethernet, Wi-Fi and client hardware to make practical use of the capacity.
78228 has a wider mix of fixed broadband technologies than the basic cable-versus-fiber description suggests. The important distinction is how each network reaches the property and how that technology behaves under household use.
AT&T Fiber and Google Fiber are the two major fiber networks identified in current 78228 datasets. Their reported footprints are large enough that both should be checked independently at addresses throughout the ZIP.
Spectrum has the broadest reported wired footprint in 78228. Cable can provide substantial download capacity, but upload performance can differ materially from the fiber networks competing on the same ZIP-level market.
T-Mobile and Verizon provide wireless alternatives that do not require a dedicated fiber or cable connection to the building. Their address-level availability depends on wireless network conditions.
Satellite service remains geographically available even in a dense urban ZIP. Its higher latency and different installation requirements make it a separate category from the competing wired networks in 78228.
78228 occupies a central-west San Antonio area that includes established residential neighborhoods, major educational institutions and older housing stock alongside apartment and multifamily properties. The ZIP includes St. Mary's University and residential areas around Culebra Road, Bandera Road and the Woodlawn corridor. Those characteristics matter because the physical network serving a single-family house can differ from the wiring and provider arrangements inside an apartment or university residence.
AT&T's current San Antonio service-area information specifically lists 78228 among the San Antonio ZIP codes associated with fiber service and advertises fiber tiers up to 5 Gbps where available. This is stronger evidence than simply stating that AT&T serves San Antonio, although AT&T still requires an address check before service can be confirmed.
Current secondary datasets derived from FCC broadband records estimate Google Fiber availability at about 74.5% of 78228. That percentage means Google Fiber should be treated as a meaningful competing fiber network in the ZIP rather than a small edge-of-market provider. The percentage is still an estimate and can change as provider records are updated.
Secondary ZIP-level data estimates Spectrum cable availability at roughly 99.7% of 78228. This creates an important local distinction: the ZIP has substantial fiber competition, but Spectrum remains the most broadly reported wired network. A resident should therefore check the address for both fiber networks before assuming that Spectrum is the only wired choice, while also keeping Spectrum in the comparison when fiber is unavailable.
St. Mary's University is located at One Camino Santa Maria in ZIP 78228 and maintains multiple residence halls whose mailing addresses are also in 78228. University housing and nearby apartment properties should not be assumed to have the same provider options as detached homes because building wiring, bulk arrangements and property-level network infrastructure can affect which retail plans can actually be ordered.
Housing records for areas such as Donaldson Terrace show a mix of older homes dating from the 1940s and 1950s alongside later construction. That does not by itself determine ISP availability, but it is relevant to interpreting address-level results because conduit, wiring, utility entrances, apartment distribution systems and later network construction are tied to individual properties, not ZIP boundaries.
The most useful ZIP-specific findings are the relationships between the major networks. 78228 is not simply a high-coverage cable ZIP; current evidence indicates meaningful overlap between Spectrum, AT&T Fiber and Google Fiber.
| Finding | Evidence | What it means for a 78228 address |
|---|---|---|
| AT&T Fiber | AT&T's current San Antonio information specifically identifies 78228 with Fiber up to 5 GIG; secondary ZIP data estimates about 97% coverage. | AT&T Fiber should be checked before treating AT&T as a legacy DSL or wireless-only option. |
| Google Fiber | Current secondary FCC-derived datasets estimate Google Fiber at approximately 74.5% of 78228. | A substantial portion of the ZIP may have a second fiber network, making address-level fiber comparison especially important. |
| Spectrum | Current ZIP-level datasets estimate Spectrum cable coverage at approximately 99.7%. | Spectrum remains a broadly relevant wired option even where one or both fiber networks are available. |
| T-Mobile Home Internet | Current ZIP-level broadband data identifies T-Mobile fixed wireless service in 78228. | 5G Home Internet provides another option, but address eligibility depends on capacity and radio conditions. |
| Verizon fixed wireless | Current ZIP-level broadband datasets identify Verizon fixed wireless service in 78228. | Verizon is worth checking independently rather than inferring eligibility from general San Antonio 5G coverage. |
| EarthLink | Secondary ZIP data reports EarthLink fiber, DSL and fixed-wireless service in 78228. | The actual underlying technology should be identified before comparing EarthLink with AT&T or Google Fiber. |
| Smaller fixed wireless | ZIP-level records identify smaller providers including VTX1 Companies and other limited-footprint networks. | These are property-specific possibilities rather than ZIP-wide default choices. |
These locations are geographic reference points for understanding the ZIP's housing and infrastructure mix. They are not claims that every property in an area has the same ISP options.
Adjacent ZIP codes can have different network footprints. They are separate research areas and should not be used as substitutes for checking a 78228 address.
Because 78228 has overlapping fiber and cable networks, the useful verification process is to check each physical network separately rather than selecting a provider from a ZIP-level list.
Brands such as EarthLink can offer service over more than one access technology. Before comparing an EarthLink offer with AT&T Fiber, Google Fiber or Spectrum, determine whether the address is receiving fiber, DSL, fixed wireless or another access type. The physical technology can matter more than the provider name in the comparison.
The local evidence makes 78228 a useful example of why a provider list should be followed by a technology and address-level comparison.
Current ZIP-level evidence reports substantial footprints for both AT&T Fiber and Google Fiber. Do not stop after finding one fiber provider because the second network may be available at the same property.
Spectrum's broad cable footprint means it can remain available even where fiber is present. Compare upload speed, latency and actual technology rather than treating equal download numbers as equivalent.
78228 includes older single-family housing, apartments and university residences. For multifamily properties, ask whether the building and unit are physically wired for the advertised provider and plan.
ZIP-level research identifies the local market. Provider address tools determine which networks and plans can actually be ordered at the property.
This page gives greater weight to current provider information for service-area and plan claims and uses FCC Broadband Data Collection- derived datasets as the primary ZIP-level coverage layer. Secondary datasets are treated as estimates rather than live ordering systems.
