Rootmetrics, a company which measures mobile network performance, conducted the tests based on parameters like data speeds, calls and text performance on 400,000 test samples during the second half of 2015. The tests were conducted on all major networks like EE, O2, Three and Vodafone and the scores were weighed as per estimated number of subscribers for each carrier.
EE is still the best bet when it comes to network performance and speed
In overall rankings, Liverpool slipped to third with its score dropping slightly from 94.6 to 94.5. Birmingham retained its second place despite improving its score from 94.1 to 94.6 while Manchester improved its performance from 93.5 to 95.4 in just six months.
Hull, Bristol and Cardiff continued to occupy the bottom three positions in the table but Cardiff dropped points significantly from 83 to 79.2, allowing Hull to close the gap. Scottish and Northern Irish cities like Edinburgh, Glasgow and Belfast offered better calling, texting and data performance than London whose points tally dropped from 90.5 to 90.1!
EE apparently most glitch-free network, says RootMetrics
In terms of performance on individual parameters, Manchester topped the table data performance and network reliability while Liverpool held ground for network speed. Hoever, London disappointed yet again, having ranked tenth at best among all parameters.
Despite finishing fourth in overall rankings, Coventry topped in call performance with a score of 97.4 while London appeared in the bottom three on the same parameter, scoring just 90.5.
"There’s just no getting away from the Manchester-Liverpool rivalry, and throughout 2015 the two cities have been tussling for the mobile top spot. While Manchester scored the most points in the second half of the year, people using their phones in Liverpool, and Birmingham too, can expect a strong overall mobile performance whatever network they are on,” said Scott Stonham, RootMetrics General Manager of Europe.

Back in February, Rootmetrics conducted a survey on metrics like Overall Performance, Network Reliability, Network Speed, Mobile Internet, Call, and Text in the second half of 2015. EE scored an impressive 88.1 out of 100 in overall ratings. Three followed a bit behind at 84.5 while Vodafone and O2 huffed and puffed to the finish line with 78.6 and 76.6 respectively.
Vodafone and O2 offered better overall performance than in the first half of 2015 when they scored 74.5 and 72.7 respectively. However, EE's overall score came down from 89.4 to 88.1 in the same period, which means that the gulf between E and the bottom performance isn't as much as it was in the first half of 2015.
