Internet in Columbia, South Carolina
Fiber is available at 70.4% of the 39,240 homes and businesses the FCC counts in Columbia, and wired broadband of at least 100/20 Mbps at 95.8%. 70.2% of locations have a choice of two or more wired providers at that speed; at 25.6% there is only one.1

Columbia in South Carolina
Columbia is two cities on the FCC map. Where fiber reaches, 70.4% of homes and businesses, there is also Spectrum's cable and so a choice of wired service. Everywhere else Spectrum is the only fast wire, at 24.3%1 of locations; in 2022 a single fast wire was the rule at 49.2%2.
Spectrum, AT&T and T-Mobile's Lumos fiber
The FCC map counts 39,240 homes and businesses inside Columbia's city limits as of June 30, 2026 (revision of November 10, 2026). Spectrum reports service at 94.4% of them, almost all over cable, with 100/20 Mbps or more at the same share. AT&T reports 92.2% through three technologies: fiber at 50.4% of locations, older DSL lines and fixed wireless on most of the rest. T-Mobile appears high in the list for two separate networks: fiber at 33.2%1 of locations, filed in the FCC's location files under the Lumos brand, and 5G home internet.

Source: FCC, National Broadband Map, data as of June 30, 2026. Share of the area's broadband serviceable locations where the provider reports service as of June 30, 2026. "Only wired option" is the share of locations where it is the single wired provider at 100/20 Mbps. Provider-reported and challengeable; speeds are advertised maximums, not measured; no prices. Satellite providers (Viasat, Starlink, HughesNet) report service at nearly every location and are left out of the table.
Below the four large names the list thins fast. CarolinaConnect Cooperative reports fiber at 185 locations, TruVista Communications at 158 and Comporium at 241. A provider "reports service" when it tells the FCC it could connect the location within ten business days with a standard installation; the claim can be challenged on the FCC National Broadband Map, and it says nothing about price.
Fiber from under half the city to most of it
In June 2022, fiber was reported at 37.6% of Columbia's locations, close to the state's 36.1%2. Four years later it is reported at 70.4%, a rise of 32.8 percentage points and the 88th highest increase among the 343 cities of 100,000 or more. The last six months alone added 5.1 percentage points. Columbia now has a larger fiber share than South Carolina (67.4%), the US (62.6%), Charleston (55.4%) and North Charleston (43.2%). Among all large cities its share is 160th lowest1, near the middle, as the strip below shows.

Two networks account for almost all of it. AT&T was already the main fiber provider in 2022 and has extended its footprint. Lumos did not appear in the city in the June 2022 map at all; it now reports fiber at 33.2% of locations. Two or more fiber networks are reported at 17.6% of locations, up from 0.0%2 in 2022 and above South Carolina's 13.0%1.

The count of fiber providers rose from 32 to 6, but apart from AT&T and Lumos each covers a small corner; the widest of the rest is Spectrum, which reports fiber at 3.5%1 of locations.
Where fiber stops, Spectrum is alone
The striking pattern in Columbia's figures is how neatly they line up. Fiber is reported at 70.4% of locations, two or more wired providers at 100/20 Mbps at 70.2%, and symmetrical 100/100 Mbps service at 70.4%. On the rest of the map, 25.6% of locations, one wired provider offers 100/20 Mbps, and that provider is Spectrum at 24.3%. AT&T's older DSL lines are still reported at 67.3%1 of locations, but where Spectrum is the only fast wire, AT&T offers nothing at 100/20 Mbps.
Source: FCC, National Broadband Map, data as of June 30, 2026. Different wired providers (fiber, cable or DSL; FCC provider IDs) reporting 100 Mbps down and 20 Mbps up or more at the same location. Fixed wireless and satellite are not counted.

| United States | 7.8% | 36.6% | 44.6% | 11.1% |
That single-wire share has halved since June 2022, when it stood at 49.2%, and three or more wired choices, reported at 0.0%2 of locations in 2022, now cover 17.8%1.
Fast wired service is missing at only 1,653 locations, and 631 are unserved under the BEAD definition (no wired or licensed fixed wireless service at 25/3 Mbps).
Speeds: 5 Gbps on fiber, slow uploads on cable
The fastest advertised download is 2 Gbps or more at 65.0% of locations, against 21.0%2 in 2022; AT&T and Lumos both advertise up to 5 Gbps on fiber. Spectrum advertises up to 1 Gbps downloads on cable, but in the FCC files its Columbia cable uploads stay below 100 Mbps. That is why gigabit service with fast uploads, the FCC's 1,000/100 tier, is reported at 70.4%, the same as the fiber share, while a 1 Gbps download alone is reported at 95.5%1. These are maximum advertised speeds reported to the FCC, not measurements.

5G home internet from three carriers
Licensed fixed wireless, which includes 5G home internet, is reported at 95.3% of locations by 3 carriers, against 2 in 2022. T-Mobile reports home internet at 87.9% of locations and offers 100/20 Mbps at 52.1%, a figure that includes its Lumos fiber; Verizon reports 86.8% with 100/20 Mbps at 50.1%. AT&T's fixed wireless is advertised at no more than 100 Mbps. Fixed wireless at 100/20 Mbps or more is reported at 63.2%1 of locations, up from 23.4%2, though wireless capacity is shared on each tower sector and carriers accept sign-ups address by address.
Choice compared with Charleston and the state
Columbia's competition comes from fiber laid beside cable. In Charleston a second cable network carries more of it, which gives that city more locations with two fast wires (76.1%) despite less fiber. Columbia's share with two or more, 70.2%, is well above South Carolina's 54.8% and the US figure of 55.6%, and its average is 1.841 wired providers at 100/20 Mbps per location.

Subscriptions: up since 2019, low among large cities
The Census Bureau's 2025 survey counts households, not locations, and measures subscriptions rather than availability. In it, 8.7% of Columbia households had no internet subscription (margin of error ±3.1 percentage points), the 22nd highest share among large cities by point estimate. That is down from 14.9% in 2019 (±2.3 percentage points), and the two ranges do not overlap. Subscriptions to cable, fiber or DSL rose from 72.0%5 to 80.0% (±4.0 percentage points), and 9.7%4 of households relied on a cellular data plan alone.

Availability is a share of locations as of June 30, 2026 (FCC); subscriptions are a share of households from the American Community Survey, 2025 (whiskers: 90% margin of error). Different units and dates: read the gap as a sign, not an exact number.

Checking one address in Columbia
The figures on this page describe the whole area. Which providers report service at a single home or apartment is shown only on the FCC's own map: search the address at broadbandmap.fcc.gov. If a provider is listed there but cannot actually connect you within ten business days, or the location is missing or misplaced, the map has a button to file a challenge; providers must respond, and corrections flow into later releases. Prices and plans are not part of the FCC data: each provider must show them on its broadband facts label at the point of sale.
