C Spire's home internet is mostly a Mississippi network: 1,232,915 of the 1.4 million homes and businesses it lists in 4 states as of June 30, 2026 are there, 93.0% of all Mississippi locations. Most of that statewide reach is licensed fixed wireless filed at 100 Mbps. Its fiber, at 396,0001 locations, is split between Mississippi and a few Alabama cities.

One brand, two very different networks

In Mississippi, the answer to "is C Spire available" is almost always yes on paper: as of June 30, 2026 (FCC file revision of November 10, 2026), C Spire reports service at 93.0%1 of the state's homes and businesses. The useful question is which network reaches a given location, because the FCC filing describes two services with little in common.

The larger one is licensed fixed wireless, a radio link from a tower to an antenna at the home. C Spire reports it at 1,014,287 locations, every one of them in Mississippi, and files all of them at 100 Mbps download, which is both its top wireless tier and enough to count at 100/20 Mbps. By locations, C Spire has the sixth-largest licensed fixed wireless footprint among the 375 brands that report one, behind T-Mobile, Verizon, AT&T, Nextlink Internet and Wisper ISP, LLC1.

The second is fiber to the premises, at 396,364 locations, with advertised downloads up to 10 Gbps. Two small pieces complete the filing: cable at 13,621 locations (up to 1 Gbps), all in Alabama, and copper DSL at 8,639 locations in Mississippi, none of it at 100/20 Mbps (fastest tier 25 Mbps1). A location can be counted under more than one technology.

Mississippi: near-total reach, fiber at a fifth

Of Mississippi's 1,325,975 broadband serviceable locations, C Spire lists 1,232,915. The next-largest footprints, satellite excluded, are AT&T at 62.1% of the state and T-Mobile at 55.7%1.

The fiber share is a different number. C Spire reports fiber at 17.2% of Mississippi's locations, compared with 26.7% for AT&T. Across all providers, fiber reaches 71.2% of the state, the 15th highest1 share among the states and DC. Elsewhere in Mississippi, C Spire's filing is fixed wireless, apart from its small DSL area.

That split shows up in the state's own figures. 98.6% of Mississippi locations have at least one terrestrial (non-satellite) provider at 100/20 Mbps, but only 87.5% have a wired one. The gap is the 11.1% of locations where fixed wireless is the only way to reach 100/20, the 4th highest1 share of any state. C Spire is one of the providers filing licensed fixed wireless at that speed in Mississippi; the FCC data do not say which provider is the only 100/20 option at each of those locations.

Alabama: fiber in a handful of cities

In Alabama the picture reverses. C Spire covers only 7.2% of the state's locations, but nearly all of that is fiber (7.2%1 of Alabama locations), and the filing lists no fixed wireless there. The cable locations are also in Alabama; Troy Cablevision is among the brand names C Spire files under.

The Alabama footprint is concentrated in a few cities. C Spire reports fiber at 26.9% of Tuscaloosa and 26.3% of Montgomery, but at 0.1% of Mobile and 0.1% of Birmingham. In both Tuscaloosa and Montgomery, the cable company reaches almost every location (Xfinity at 96.8% of Tuscaloosa, Spectrum at 94.6%1 of Montgomery), so C Spire's fiber is an added wired line rather than the only one.

Fiber from any provider spread quickly in both cities. Tuscaloosa went from 37.4% of locations with fiber in June 2022 to 75.8%, and the share with two or more fiber networks from 1.5% to 14.8%. Montgomery went from 31.8%3 to 60.7%1. The FCC data record each city's total, not how much of the change came from each provider.

Jackson: every location, mostly over the air

Jackson is the only one of the 343 cities of 100,000 or more where C Spire reports service at every location (100.0%). Its fiber reaches 12.6%1 of the city; the rest of its Jackson footprint is licensed fixed wireless.

Most of Jackson's wired choice comes from other networks. Xfinity reports fiber or cable at 99.0% of locations, and AT&T reports fiber, DSL or fixed wireless at 91.5%. Fiber from any provider covers 50.3% of the city, up from 22.0% in June 2022, and the share of locations with two or more wired providers at 100/20 Mbps rose from 28.5%3 to 53.4%1.

From June 30, 2022 to June 30, 2026

C Spire's reported footprint grew by 1,210,652 locations between the first National Broadband Map and the latest release. Fiber accounts for +223,6013 of that change; most of the rest is fixed wireless in Mississippi. In the latest six months, since December 31, 2025, the filing added +196,473 locations, of which +15,2974 were fiber.

The state table shows where the change happened. Mississippi accounts for most of the growth in count, Alabama's footprint more than doubled, and the Tennessee and Florida entries, close to empty in 2022, now hold a few thousand and a few hundred fiber locations.

The FCC location list changes between releases, so part of a change can come from added or corrected locations.

Mississippi as a whole changed sharply over the same years. The share of its locations with no terrestrial 100/20 Mbps service fell from 27.2% to 1.5%, and the share counted as unserved under the BEAD definition (no reliable terrestrial service at 25/3 Mbps) dropped by 20.9 percentage points, the largest fall of any state. Over the same period, the share reachable at 100/20 only by fixed wireless went from 0.4%3 to 11.1%1.

Some of any provider's change between releases comes from the FCC's own location list, which is revised every release, and some from changes in how a company files. The map records what C Spire reported, not why.

Where C Spire is the only wired line

At 57,426 locations, C Spire's fiber or cable is the only wired service at 100/20 Mbps. Fixed wireless does not count toward this figure. In Mississippi these locations are 2.1% of the state; in Alabama 1.3%. In the large cities on this page the share is small: 0.0% of Jackson and 0.1%1 of Tuscaloosa, cities where a cable network reaches almost every location.

How to read C Spire's filing

The figures on this page are availability that C Spire reports to the FCC, as of June 30, 2026. A listed location is one where the company says it could start service within ten business days; it is not a customer count, and anyone who finds a listing wrong can challenge it on the FCC National Broadband Map. The FCC groups the filing under the holding company Telapex, Inc., with the brand names C Spire Wireless, Cspire, Franklin Telephone Co. and Troy Cablevision; this page counts all of them as C Spire.

The data contain no prices or plans, and the speeds are advertised maximums, not measurements. Prices and typical speeds appear on the broadband facts label C Spire must show at the point of sale.
