Poor phone reception is a common complaint, so it's important to do your research into a mobile network before you buy. 

Our interactive coverage map, which uses data crowdsourced by mobile analytics company RootMetrics, can help. 

Once you've found the network with the best signal in your area, browse the best and worst mobile phone networks in the UK to choose a provider that performs. Keep in mind that other operators piggy-back on EE, O2, Three and Vodafone's networks – and some of them have extremely satisfied customers.

Coverage map temporarily unavailable

We are in the process of updating our coverage map, and hope to have it up and running again very soon.

In the meantime, you can check coverage directly from the mobile network websites using the links below.

For example, if you're looking for Giffgaff coverage, use O2's coverage map.
