Cell Coverage in Zephyr: FAQ

What is the best cell phone carrier in Zephyr?

Based on crowdsourced speed tests in Durham, Telus currently leads in median download speeds. Compare carriers in the performance table above for the latest results.

Why might this page show limited data for Zephyr?

We need at least 25 recent speed tests to generate reliable local metrics. Until we reach that threshold in Zephyr, we show performance data for Durham when it is available.

What is the reliability score?

The reliability score summarizes how dependable mobile performance is in Durham. 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).
