Mobile Phone Coverage Checker

We use regulator Ofcom's mobile network coverage database to give an unbiased view of network coverage across all providers.

It'll show whether a 4G or 5G signal is available in the area and if the signal strength is likely to be strong or unreliable.

We use Ofcom data, it's asked us to include this disclaimer:

Powered by Ofcom

The data displayed on mobile coverage availability uses source data made available by Ofcom which is based on data from the mobile operators about how strong they think signal levels are at every location in the UK.

Each mobile operator has a slightly different approach to displaying coverage on its own map, including assumptions on the handsets used, levels of call reliability and the expected signal loss when indoors or in car.

Because Ofcom brings all mobile operator data together in a single place and holds it to a single, independent standard, the mobile coverage availability information above may display different levels of coverage than those seen on the operators' websites.

We would therefore recommend you also check the mobile provider's coverage checker. Mobile coverage data is created by coverage modelling, and since this is based on computer predictions is not error free.
