What is the best cell phone carrier in Snohomish?

Why might this page show limited data for Snohomish?

What is the reliability score?

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