Internet in St. Croix Island, VI

Everything below comes from the FCC's Broadband Data Collection, the filings providers are legally required to make about where they offer service. It describes the county; your own address can differ, and that is exactly why the technology mix matters.

What that means if you live here
- The USDA classes St. Croix Island as a nonmetro county with an urban population of 20,000 or more, not adjacent to a metro area (continuum code 5).

- Only 63 locations, 0.4%, are recorded with nothing at 25/3 Mbps or better.

- Fiber reaches 4,804 locations, 27.0% of the county.
- Cable reaches 99.6% of locations, more than fiber does, and it will be concentrated in the built-up parts of the county.
- Filings come from 5 providers, of which 3 offer fiber and 0 licensed fixed wireless.
- Reported fiber coverage fell by 419 locations over twelve months. That normally means a provider corrected an earlier over-report, not that service was removed.
- Served locations fell 0.77% year on year, usually a filing correction rather than a loss of service.

Your realistic options in St. Croix Island
Fiber
Fiber, if it has reached you
The best outcome by a distance: symmetric speed, low latency, no weather sensitivity, no data ceiling in practice.
- Best for
- Anyone whose address is inside a fiber build. Always check this first.
- Watch out
- Coverage stops abruptly at the edge of a build. Being a mile from fiber is the same as being fifty.
Fixed wireless
A local fixed-wireless provider
A regional operator beaming service from a tower or ridge to an antenna on your roof. In much of rural America this is the fastest thing available.
- Best for
- Counties where the FCC data shows large licensed fixed-wireless coverage, which this page tells you
- Watch out
- Needs line of sight. Quality varies enormously between operators; ask neighbours, not the sales page.
5G home internet
T-Mobile Home Internet
Home internet over T-Mobile’s cellular network. A gateway box you plug in yourself; no truck roll, no dish.
- Best for
- Rural addresses that still get a usable T-Mobile signal, often near a highway or a town
- Watch out
- Availability is decided address by address, not by town. Speed varies with how busy the local tower is.

Satellite
Starlink
Low-earth-orbit satellite. Latency is low enough for video calls and most gaming, unlike older satellite services.
- Best for
- Anywhere with a clear view of the sky and no wired option
- Watch out
- Hardware costs money up front, and heavy tree cover or a north-facing obstruction will cost you throughput
See Starlink
Equipment
A better router
Rural connections are usually limited by the link, not the router, but a poor router wastes a good link and provider-supplied units are often poor.
- Best for
- Large or awkwardly shaped houses, metal roofs, outbuildings
- Watch out
- A new router will not add bandwidth you never had. Fix the link first, then the wifi.
