Frequently Asked Questions
What is an MVNO?
An MVNO (mobile virtual network operator) sells mobile service without owning cellular infrastructure. MVNOs like CMLink lease access to major carrier networks in the United Kingdom and deliver coverage using those host networks.
Which networks power CMLink?
CMLink uses EE for coverage in the United Kingdom.
How does CMLink coverage compare to major carriers?
MVNO coverage mirrors the host networks it uses. Compare the host carrier performance above to see how those networks perform in the United Kingdom.
How can I check coverage in my area?
Use the coverage map above to explore real-time coverage. The map shows the host networks used by CMLink.
What do the performance metrics mean?
The performance metrics summarize median download speed, upload speed, and latency from crowdsourced tests on the host networks listed above. Higher download/upload and lower latency indicate a faster, more responsive connection.
What is the reliability score?
The reliability score summarizes how dependable mobile performance is in the United Kingdom. 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).
Why can parts of the coverage map look empty?
Coverage maps are built from crowdsourced tests, so areas with limited recent data can look incomplete. Coverage improves as more tests are collected.
How can I contribute coverage data for the United Kingdom?
Download the CoverageMap app and run a few speed tests with location enabled. Your results help improve coverage accuracy and unlock local rankings faster.
