AT&T Fiber
Fiber
Alamo Heights / Terrell Hills
Up to 5 Gbps
AT&T has unusually direct local evidence for 78209. Its current
San Antonio area-code information specifically lists Alamo Heights,
Terrell Hills and Olmos Park among the communities associated with
78209 and identifies fiber service up to 5 GIG. AT&T's broader
San Antonio page also confirms fiber availability in parts of the city
with speeds up to 5 Gbps.
- AT&T specifically associates 78209 communities with fiber rather than relying only on a citywide claim.
- Fiber availability can differ between individual streets and properties.
- AT&T's address checker determines the actual technology and tier available.
Local evidence:
AT&T's June 2026 area information lists Alamo Heights, Olmos Park
and Terrell Hills with ZIP 78209 and fiber service up to 5 GIG.
Availability remains subject to exact-address verification.
Google Fiber
Fiber
Large reported footprint
Up to 8 Gbps
Google Fiber is one of the most important reasons 78209 should not be
treated as a conventional single-cable-provider market. Current ZIP-level
datasets report Google Fiber across approximately 39% of 78209. Google
Fiber's current San Antonio network offers 1 Gig, 3 Gig and 8 Gig products,
with symmetrical upload and download speeds on those tiers where available.
- Current ZIP-level data place Google Fiber in a substantial portion of 78209.
- Google Fiber's San Antonio network uses fiber-to-the-home infrastructure.
- Google Fiber availability remains address-specific despite the ZIP-level footprint.
Local evidence:
Current 78209 datasets report approximately 39% Google Fiber coverage.
Google Fiber's current San Antonio service page lists 1 Gig, 3 Gig and
8 Gig products and states that it is continuing to expand its Texas
network.
Astound Broadband
Fiber + cable
Large local footprint
Up to 1.5 Gbps
Astound is particularly significant in 78209 because current records
identify both cable and fiber service. ZIP-level data report roughly
75% cable availability and roughly 28% fiber availability. Those
percentages overlap rather than representing separate households, but
they demonstrate that Astound's local network is not limited to a
single technology.
- Astound cable is reported across a large share of 78209.
- Astound fiber is reported across a substantial smaller footprint.
- The exact technology at an address matters when comparing upload capacity.
Local evidence:
Current ZIP-level FCC-derived records report approximately 74.6% Astound
cable coverage and 28.5% Astound fiber coverage. The two figures should
not be added because the reported footprints can overlap.
Spectrum
Cable
Very large ZIP footprint
Fiber reported in limited areas
Spectrum remains one of the broadest wired networks in 78209. Current
ZIP-level records report cable coverage across approximately 97% of
the ZIP, while a much smaller portion is classified as Spectrum fiber.
That combination makes Spectrum an important baseline comparison even
where fiber alternatives are present.
- Cable is the dominant Spectrum technology reported in 78209.
- A smaller Spectrum fiber footprint is also identified in current records.
- The advertised download number should be compared with the actual upload technology at the property.
Local evidence:
Current 78209 data report approximately 97.2% Spectrum cable availability
and approximately 3.5% Spectrum fiber availability. These are provider-
reported dataset estimates, not guarantees for individual addresses.
T-Mobile 5G Home Internet
5G fixed wireless
Alamo Quarry Market
Capacity-dependent
T-Mobile has direct physical evidence of Home Internet activity inside
78209. Its official Experience Store at 255 E Basse Rd Ste 1524 in
Alamo Quarry Market lists T-Mobile Home Internet and an availability
check. Current fixed-wireless datasets also show T-Mobile as one of the
major wireless networks reported in the ZIP.
- The Alamo Quarry Market location is inside ZIP 78209.
- Home Internet uses T-Mobile's cellular network rather than dedicated fiber or coax.
- Eligibility can change by address because capacity and radio conditions vary.
Local evidence:
T-Mobile's official Alamo Quarry Market store is at 255 E Basse Rd
Ste 1524, San Antonio, TX 78209 and explicitly lists Home Internet.
A local store establishes service presence, not universal eligibility
for nearby residences.
Verizon 5G Home Internet
Fixed wireless
Large reported footprint
Address dependent
Verizon is a significant fixed-wireless competitor in the 78209
broadband market. Current ZIP-level datasets report substantial Verizon
availability, making it relevant even in a ZIP with several wired
networks. Wireless eligibility should be checked independently rather
than inferred from general mobile coverage.
- Fixed-wireless eligibility depends on Verizon's local network conditions.
- Indoor signal and building construction can affect the practical connection.
- Network capacity can change the availability result for individual addresses.
Evidence standard:
Verizon is included because current 78209 broadband records identify
substantial fixed-wireless availability. The dataset is treated as
evidence of a local market presence rather than an address-level order
confirmation.
Hotwire Communications
Fiber
Small reported footprint
Building dependent
Hotwire Communications appears in current 78209 fiber records, but its
reported footprint is much smaller than the major networks. This type
of limited fiber presence can be particularly relevant to individual
buildings or developments where infrastructure has been installed for
a specific property.
- Current ZIP-level data report approximately 2.6% Hotwire fiber coverage.
- Small footprints should not be generalized to surrounding streets.
- Building-level verification is especially important for multifamily properties.
Evidence standard:
Hotwire is treated as a limited local fiber possibility because the
reported ZIP footprint is small relative to AT&T, Google Fiber,
Spectrum and Astound.
Alamo Broadband
Fixed wireless
Small local footprint
Verify address
Alamo Broadband appears in current fixed-wireless records for 78209,
but its reported footprint is only a small portion of the ZIP. It is
therefore more useful as a property-specific possibility than as a
general provider for every 78209 household.
- Current local datasets report a small Alamo Broadband footprint.
- Fixed-wireless service can depend on line-of-sight and local capacity.
- An exact-address check is necessary before including it in a final comparison.
Evidence standard:
Alamo Broadband is included as a limited-footprint provider based on
current ZIP-level fixed-wireless records rather than a claim of
universal service throughout 78209.
