RootMetrics: EE is the best network in London


Mobile analytics firm took more than 88,000 on-the-ground samples as EE win for fourth consecutive test

EE has been labelled the best mobile network in London for the fourth consecutive time in tests carried out by mobile analytics firm RootMetrics.

All four of the UK’s major operators were tested by RootMetrics, with EE bagging a score of 93.5 out of 100, beating Three (90.5/100), O2 (89.8/100) and Vodafone (88.1/100).

For data, Three was the most reliable network but EE was fastest, with an average download speed of 23.1Mbps, up from 17.7Mbps in the last RootMetrics test carried out in April.

For calls, Three (92.3) edged out O2 (92.1) and EE (91.4). However, Three came last for texts with a score of 94.8, losing out to EE (95.8), O2 (95.5) and Vodafone (94.9).

An EE spokesperson said: “Yet more independent network testing, and more of the same results – for phone calls, texts and superfast data, EE is providing customers with the best mobile experience.

“More than ever, consumers, businesses and MVNOs are choosing their mobile provider based on network performance, and these comprehensive tests from RootMetrics, as well as the likes of P3, GWS and Ofcom, are helping customers to make informed decisions on what really matters.”


RootMetrics took 88,253 samples of calls, texts and data to compile its Overall RootScores, which are ranked out of 100, in tests that ran between October 22 and October 30.

The tests covered 2,512 miles across the capital, with 85 indoor locations randomly tested. RootMetrics determines its score by assessing median upload and download speed, reliability of data transfers, call success (including frequency of blocked and dropped calls), and the speed that text messages are sent and received.

The results are compiled into what RootMetrics calls its RootScore, although it does not share how the date is weighted.

RootMetrics CEO and President Bill Moore said: “Our testing is meant to show people in London how the mobile networks perform in real-world situations. EE has again shown itself to be the top-performing network in the city, but all four networks have improved in terms of both overall performance and network reliability since our testing in April.

“Three and EE again ranked first on our Network Reliability Index, but O2 and Vodafone are closing the gap. This level of competition is great news for residents of London.”
