Best Cell Carrier in Mattoon

Every carrier gets 0 to 10 scores inspired by the CoverageMap API's scoring, adapted to a whole area so each one agrees with the numbers we show:

• Coverage is how much of the area the FCC reports as covered, lowered when speed tests fail to connect. Speed never counts here, so the carrier that reaches the most of the area has the best coverage. Carriers nobody has tested here are rated from the FCC map alone: performance is the share of the area with a good or better signal, and reliability is how little of their coverage is weak.
• Performance blends median download (70%) and upload (30%) speeds, topping out at 100 and 20 Mbps, and is lowered by latency over 150 ms. The first Mbps count the most, so a solid 50 Mbps scores well.
• Reliability looks at the slowest tests (the worst 10%) against 10 Mbps down and 2 Mbps up, and every failed test counts fully against it, so it shows how a network holds up when it's busy.

In coverage and performance, failed tests count half as much because some fail for reasons that have nothing to do with the network. The overall score weighs coverage 50%, reliability 30%, and performance 20%, and our pick has the best overall score. Each activity uses the measurements that matter for it: latency for gaming and video calls, download speed for streaming, coverage for rural areas, and fast, steady speeds both ways for home internet.

We need at least 25 speed tests in Mattoon to rate speeds locally, and 10 for each carrier before we compare its speeds. With fewer tests, we use a larger nearby area or rate carriers from FCC coverage alone.
