There are a number of steps you can take to check and improve your mobile phone reception, whether you are a consumer or business customer.
You can check mobile coverage for telephone, 3G and 4G services from all major providers by using our coverage checker.
You can download it as a smartphone app or you can use it via an internet browser. You will need to enter a postcode, or allow the checker to automatically find your location, in order to see the coverage information. The checker provides an at-a-glance summary of services in your area, and you will also be given the option to view your chosen area using an interactive map - you can also then navigate to any area in the UK on this interactive map.
The information in the coverage checker provided by mobile operators, and is updated regularly. It is based on coverage predictions generated using computer programmes that simulate the way mobile signals travel. Although these models are usually accurate, they may not always represent actual coverage ‘on the ground’. Ofcom also undertakes its own measurements to assess the accuracy of the data provided.
Some mobile providers also offer their own coverage checkers for their services, which you can find online. Each operator has a slightly different approach to predicting and displaying coverage. Because Ofcom's map brings together all of this data in a single place and holds it to a single, independent standard, our map may display different levels of coverage than those seen on the operators' websites.
