The latest FCC-derived ZIP-level dataset reviewed for this guide is based on Broadband Data Collection information through December 31, 2025 and was updated in September 2026. It identifies six providers with at least 1% reported coverage in 33157 and shows four terrestrial connection types: fiber, cable, DSL and fixed wireless.
The ZIP-level dataset reports AT&T fiber across approximately 92.5% of 33157, with maximum reported service up to 5 Gbps. AT&T's own Miami-area records also identify Palmetto Bay and Cutler Bay, including ZIP 33157, within its fiber service information. Availability still depends on the individual property.
Xfinity cable is reported across approximately 99% of 33157 in the recent ZIP dataset, with up to 2 Gbps reported in the data. The same dataset shows only a very small Xfinity fiber footprint, so cable should be treated as the principal Xfinity technology for most of the ZIP rather than assuming every Xfinity address is fiber.
T-Mobile Home Internet is reported across about 93.7% of the ZIP in the FCC-derived dataset, while Verizon fixed wireless is reported across about 89.7%. T-Mobile also has a Home Internet-enabled store at 15801 S Dixie Hwy in Palmetto Bay, directly inside ZIP 33157.
The coverage figures below come from the most recent ZIP-level dataset reviewed for this page. They describe reported service footprints, not live ordering eligibility. Provider names that appear under multiple technologies can represent different network types and should be checked at the property.

|
SkyNet360
Fixed wireless
|
Fixed wireless | Recent FCC-derived data reports SkyNet360 fixed wireless across approximately 90.2% of 33157, with a reported maximum of 160 Mbps. It is a meaningful secondary wireless option in the ZIP dataset. | Up to 160 Mbps | Exact address, line-of-sight/network conditions and plan terms |
|
Satellite providers
Broad geographic option
|
Satellite | Satellite services are geographically available throughout the ZIP and do not depend on the same local fiber or cable plant as terrestrial providers. | Provider and plan dependent | Clear sky view, latency, equipment and plan terms |
The provider descriptions distinguish direct provider evidence from FCC-derived ZIP records. This matters in 33157 because the ZIP crosses several communities and the physical broadband networks do not follow those community boundaries exactly.
AT&T has the clearest fiber evidence for 33157. The current FCC-derived ZIP dataset reports AT&T fiber across approximately 92.5% of the ZIP, with maximum reported service of 5 Gbps. AT&T's own Miami-area service records identify both Palmetto Bay and Cutler Bay among communities associated with its fiber service and include ZIP 33157 in those records.
Xfinity is the other major wired network identified in the current ZIP-level data. Approximately 99% of 33157 is reported as having Xfinity cable availability, while only about 0.9% is reported as Xfinity fiber. That distinction is useful because a generic provider list can otherwise make Xfinity's technology footprint appear more uniform than the underlying data supports.
T-Mobile is more than a generic wireless alternative in 33157. The company has a South Dixie Highway store at 15801 S Dixie Hwy, Suite E, Palmetto Bay, FL 33157, and its official location page specifically lists T-Mobile Home Internet. The recent ZIP dataset also reports fixed-wireless coverage across approximately 93.7% of the ZIP.
Verizon's fixed-wireless network is another substantial part of the 33157 broadband market. The recent FCC-derived dataset reports Verizon fixed wireless at approximately 89.7% of the ZIP and a maximum reported download speed of 300 Mbps. Verizon itself emphasizes that 5G Home Internet availability depends on the specific address and that cellular coverage does not automatically equal home-internet eligibility.
EarthLink appears in the latest reviewed ZIP-level dataset with a fiber footprint of approximately 92.5%, closely matching the reported AT&T fiber footprint. The dataset also lists EarthLink DSL and fixed wireless. Because the fiber footprint closely tracks AT&T's reported coverage, this page does not assume that EarthLink represents an entirely separate physical fiber network.
SkyNet360 is a smaller fixed-wireless provider that appears in the current ZIP-level dataset with approximately 90.2% reported coverage and a maximum reported speed of 160 Mbps. Its inclusion is useful because the 33157 market is not limited to the large national cable, fiber and cellular providers.
The ZIP has enough fiber and cable overlap that speed comparisons should include upload capacity and technology, not just the advertised download number. Fixed wireless can also be competitive for some addresses even though its performance characteristics are different from wired service.
Appropriate for ordinary browsing, video calls, streaming and smaller households when the connection is stable.
Useful for households with several simultaneous users, multiple streaming devices and heavier downloads.
Relevant for larger households, substantial downloads and homes with many simultaneously active devices. Both fiber and cable can reach this range in the broader 33157 market.
AT&T reports fiber service up to 5 Gbps where available in the Miami area. The relevant question for 33157 is whether the specific property is connected to the qualifying fiber network.
The ZIP has four major terrestrial connection types in the recent broadband dataset, plus satellite alternatives. The physical differences between those networks are especially relevant because 33157 has substantial overlap between fiber, cable and fixed wireless.
AT&T is the primary fiber network identified in the current ZIP-level data, with approximately 92.5% reported coverage and maximum speeds up to 5 Gbps. EarthLink is also reported with a closely matching fiber footprint, but its physical underlying network should be verified rather than assumed to be separate.
Xfinity cable is reported across approximately 99% of 33157. That makes cable an important comparison against AT&T fiber for many addresses, particularly when upload performance and pricing are evaluated alongside download speed.
T-Mobile and Verizon both have substantial reported fixed-wireless footprints in 33157, while SkyNet360 is also listed in the current ZIP data. Wireless eligibility can change by address because network capacity and signal conditions are not identical across the ZIP.
DSL remains in the ZIP-level data through AT&T and EarthLink, although it is materially different from the current fiber footprint. Satellite services provide geographic coverage independent of the local terrestrial cable and fiber plant.
33157 is unusually important to treat as a multi-community ZIP rather than as a single Miami neighborhood. Postal and geographic records place portions of the ZIP in Palmetto Bay, Cutler Bay, Palmetto Estates, West Perrine, South Miami Heights and East Perrine. That geography helps explain why provider footprints should be interpreted at the property level rather than by city name alone.
The ZIP's primary postal city is Miami, but accepted postal names include Cutler Bay, Cutler Ridge, Palmetto Bay and Perrine. Other geographic datasets place portions of the ZIP in Palmetto Estates, West Perrine, South Miami Heights and East Perrine. A provider description that simply says "Miami service" therefore misses meaningful local geography.
The latest FCC-derived ZIP dataset reports AT&T fiber across approximately 92.5% of 33157, with a maximum reported speed of 5 Gbps. AT&T's own area records identify Palmetto Bay and Cutler Bay, including ZIP 33157, in its fiber service information. The combination provides stronger ZIP-specific evidence than a generic statement that AT&T serves Miami.
Xfinity cable is reported across approximately 99% of 33157 in the recent dataset. Only a very small Xfinity fiber footprint is reported, so the important local comparison for most homes is AT&T fiber versus Xfinity cable rather than assuming two equivalent fiber networks are available throughout the ZIP.
T-Mobile Home Internet is reported across approximately 93.7% of 33157, while Verizon fixed wireless is reported across approximately 89.7%. SkyNet360 is also reported across about 90.2%. These figures make fixed wireless a significant part of the local broadband market, although the technology remains more dependent on wireless network conditions than the wired options.
T-Mobile operates a store at 15801 S Dixie Hwy, Suite E, Palmetto Bay, FL 33157, and the official store record lists Home Internet as an available service. This does not establish residential service at every nearby address, but it provides direct provider evidence within the ZIP rather than relying solely on a citywide service statement.
The current ZIP-level dataset reports EarthLink fiber coverage at approximately the same level as AT&T fiber, about 92.5%. Because the footprints closely match, this page treats EarthLink as a provider option but does not claim that its presence proves a second independent physical fiber network across 33157.
The following findings connect the ZIP-level data to the actual geography and network mix of 33157 instead of presenting a generic national provider list.
| Finding | Evidence | What it means for a 33157 address |
|---|---|---|
| AT&T fiber | Approximately 92.5% reported fiber coverage in the current ZIP-level dataset; AT&T area records identify 33157 in Palmetto Bay and Cutler Bay fiber information. | Fiber should be checked directly before treating AT&T as a legacy DSL-only provider. |
| Xfinity cable | Approximately 99% reported cable coverage in 33157; only about 0.9% is reported as Xfinity fiber. | Xfinity is a major wired alternative, but cable should be assumed only after the property's technology is confirmed. |
| T-Mobile Home Internet | Approximately 93.7% reported fixed-wireless coverage; official T-Mobile store at 15801 S Dixie Hwy lists Home Internet. | 5G home internet is a substantial local alternative, not merely a theoretical nationwide option. |
| Verizon 5G | Approximately 89.7% reported fixed-wireless coverage in the current ZIP dataset. | Verizon is worth checking independently, but the ZIP percentage is not a live eligibility result. |
| SkyNet360 | Approximately 90.2% reported fixed-wireless coverage with a reported maximum of 160 Mbps. | A smaller wireless provider is present in the ZIP-level market and can matter where wired choices differ. |
| EarthLink | Approximately 92.5% reported fiber coverage, closely matching AT&T, plus DSL and fixed wireless records. | EarthLink should be checked as a provider option without assuming it represents a separate physical fiber build. |
| Multi-community ZIP | 33157 includes portions of Palmetto Bay, Cutler Bay, Palmetto Estates, West Perrine, South Miami Heights and East Perrine. | City-level provider descriptions are insufficient to establish the exact network options for every part of the ZIP. |
The locations below are geographic reference points for understanding the ZIP's broadband market. They are not claims that one provider serves an entire community uniformly.
Neighboring ZIP codes can have different provider footprints even when they are part of the same South Miami-Dade broadband market. Use them as separate research areas rather than treating nearby ZIPs as interchangeable.
The correct sequence is to identify the networks reported in the ZIP, then check the exact property with each relevant provider. This is particularly important in 33157 because several technologies have substantial reported footprints.
FCC-derived data is useful for establishing that fiber, cable and fixed wireless are reported in 33157 and for identifying the relative size of those footprints. It is not a live ordering system. The exact provider address checker should take precedence when determining whether a particular home, apartment or unit can actually order service.
Because 33157 has substantial overlap between fiber, cable and fixed wireless, a useful comparison should identify the actual technology available at the property before comparing advertised speeds.
AT&T fiber can provide symmetrical upload and download capacity where available, while Xfinity's principal reported 33157 footprint is cable. The difference can matter for cloud backups, large file transfers, remote work and other upload-heavy activity.
T-Mobile and Verizon both have substantial reported footprints in 33157, but wireless eligibility and performance can vary by address. A nearby qualifying property does not establish eligibility for another home.
33157 spans several communities and accepted postal place names. A provider's Miami, Palmetto Bay or Cutler Bay service page can establish regional presence, but the exact address is still the correct unit for availability verification.
ZIP-level research identifies the local market. Provider address tools determine what can actually be ordered at the property.
This page gives greater weight to current official provider information for local service-area and plan claims, while using recent FCC Broadband Data Collection-derived ZIP data as the primary secondary coverage layer.
