Now you can find out where the best mobile network coverage is

13 November 2014

mobile phone An app has been created which can indicate the strength of the mobile signal in a certain area.

OpenSignal have invented a heat map, which uses crowd-sourced data, showing 2G, 3G and 4G signal available to users throughout the UK on the major networks – Three, EE, Vodafone and O2.

It shows that - shock - the strongest signals are to be found around cities, where 4G speeds range from 12Mbps to 15Mbps, however the UK still has some catching up to do in a lot of areas.

The map also shows that EE has the best 4G coverage, encompassing 75% of the UK population over 300 towns and cities, and also offers the best overall performance.

However up in Scotland, Three offers the best 4G performance, and in Nothern Ireland Vodafone are the victors with their average download speed of 19.3Mbps

In Scotland, however, Three offers the best 4G performance, with an average download speed of 10.6Mbps and upload speed of 7.0Mbps; while in Northern Ireland, Vodafone has the best 4G performance with an average download speed of 19.3Mbps and upload speed of 9.9Mbps.

Jay Karsandas, digital manager at, who licensed the maps from OpenSignal, said: “Despite a slow start, the UK has made significant progress in the provision and speed of 4G. It is likely that the initially high price point of 4G dissuaded consumers from taking contracts that utilised the high-speed technology. With a range of flexible and competitive 4G plans on offer by major retailers, and a race to provide the most UK coverage, 4G will inevitably be the future of mobile connectivity."

This comes after the report which OpenSignal had done with Which!!!, which showed that average speeds on 4G mobile networks had almost halved in the past year. Ironically, the slowdown is attributed to more and more 4G subscribers, but not enough 4G masts.

Fancy that!
