SignalCheck.uk helps you find the best mobile network for your area. We compare 4G and 5G signal strength from EE, Three, O2 and Vodafone across 2,289 UK postcode districts.
Coverage data is based on Ofcom's Connected Nations reports and operator coverage data. We process this into easy-to-understand comparisons showing indoor coverage, outdoor coverage, voice quality, and 5G availability for every postcode district in the UK.
Each network receives a score out of 100 for every postcode district, weighted across outdoor 4G (30%), indoor 4G (30%), voice coverage (20%), and 5G availability (20%). The network with the highest score is marked as the "Best Network" for that area.
