Cell Coverage in Cornwall: FAQ

What is the best cell phone carrier in Cornwall?

We don't yet have enough speed tests in Cornwall to rank carriers. Once we reach 25 tests, we'll publish local rankings.

Why might this page show limited data for Cornwall?

We need at least 25 recent speed tests to generate reliable local metrics. If we don't have enough tests yet, the page focuses on maps and nearby locations while we keep collecting data.

What is the reliability score?

The reliability score summarizes how dependable mobile performance is in Cornwall. It uses a 0.0 to 10.0 scale (higher is better) and is calculated from real-world speed test percentiles with weighted components: download (50%), latency (30%), and upload (20%). It evaluates the lower-end experience using the bottom 10%, 5%, and 1% percentiles when enough samples are available. If local speed testing is limited, a coverage-based fallback is used from signal quality distribution (great/good/poor).
