EE comes out on top in RootMetrics testing in London


 Operator achieves overall score of 92.2 out of 100, and finished in first or joint top in four out of the five sub-categories

EE has been ranked the top mobile phone network in London following the latest round of testing by independent mobile analytics firm RootMetrics.

This is according to 88,670 on-the-ground samples collected by the firm, which were the first tests since all major operators have been providing 4G in the capital.

Overall, EE achieved a score of 92.2 out of 100, with O2 and Three tied for second with scores of 88.5 and 87.5 respectively (O2 and Three tied in this position as their scores were statistically comparable). Vodafone was last with a score of 86.

These scores brought together results from the RootMetrics mobile internet, call and text message tests, and show how reliably and quickly each network performed across all the ways that consumers use their phone.

EE and Three shared the top prize for reliability with a score of 93.7, followed by O2 (88.8) and Three (87.1). EE also remains on top in the mobile internet category, scoring 93.8, with median download and upload speeds of 17.8Mbps and 9.3Mbps.

Launching 4G at the same time last august, O2’s and Vodafone’s speeds are comparable (9.6Mbps and 10.1Mbps upload and 3.2Mbps and 3.8Mbps download).

In the call performance category, there was a three-way tie for the top spot, with  O2, Three and EE all scoring 89.7, while EE just edged out O2 by 0.2 points in the text performance category, with a score of 96.

RootMetrics president and CEO Bill Moore made a point of stating that the firm’s testing was “unbiased”. In March, EE hit back at Vodafone after its rival appeared to suggest a recent test by RootMetrics – in which EE finished top and Vodafone bottom – was rigged.

“Our unbiased testing shows consumers how the mobile networks perform in real-world situations. All the major operators are now providing 4G in London, but EE is still out in front when it comes to speed, though Three made a great showing in terms of network reliability.

“Speed is great, but it’s meaningless if you cannot connect to a network wherever you are; EE and Three are the most reliable networks in London right now.”
