The Department of Science, Innovation and Technology (DSIT) commissioned this study by FarrPoint to investigate the relationship between the number of available mobile networks in a location and the resulting benefits of mobile connectivity. There are currently four mobile networks operators (MNOs) in the UK, soon to be three following the merger of two of these network operators. In the absence of any prior research or evidence, a simple model might suggest that any benefits would rise in equal increments based on the number of operators present in an area; however, this approach needed to be tested using evidence-led analysis. 

The UK mobile connectivity market, driven by major operators, is highly competitive and dynamic, offering extensive 4G and an expanding 5G service. In addition to commercial investment, there has also been significant public investment aimed at enhancing 4G coverage across rural areas.
