Mason County is better served than most rural counties. Fiber already reaches 74.5% of locations, so the first question is not what to buy but whether fiber has reached your road.
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 Mason County as a completely rural county, or one with an urban population under 5,000, adjacent to a metro area (continuum code 8).
About 12,881 people live across those locations, roughly 1.6 people per serviceable address.
8.4% of addresses here, 684 of them, fall below 25/3 Mbps or have no fixed option at all.
Another 937 can get something, but not the 100/20 Mbps the FCC now treats as the benchmark.
The most widely available technology here is fiber, reaching 6,069 locations (74.5%); next is licensed fixed wireless at 35.8%.
Fiber already reaches 74.5% of the county (6,069 locations), which puts Mason County well ahead of most rural America.
Licensed fixed wireless covers 35.8% of the county. It does not reach as far as fiber does here, but it reaches places fiber does not.
Filings come from 15 providers, of which 3 offer fiber and 5 licensed fixed wireless.
Fiber reached 249 more locations in Mason County over the last twelve months, a 3.1% swing in the county's total.
Served locations rose 3.69% year on year.
Mason County is harder-served than the typical Illinois county, where the median unserved share is 4.6%.
Fiber is further along here than in most of Illinois, where the median county reaches 58.4%.
What people actually measure in Illinois
Median of real speed tests run on each network during 2024, from M-Lab. This is measured performance, not an advertised plan speed, and not a customer review. The middle-half column shows how consistent a network is: a wide spread means your experience depends heavily on where and when.

Cellular networks, measured
The same measurement for the mobile networks behind 5G home internet. These tests come from phones as well as home gateways, so treat them as an indication of network health in the state rather than a home-internet plan speed.

Latency is the number that decides whether video calls and gaming feel right, and it is where satellite differs most from everything else. Measured data is statewide: below county level there are usually too few tests to report an honest number.

Your realistic options in Mason County
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.
