EE is the best performing UK mobile network according to RootMetrics which tests mobile network speeds across the UK. EE, owned by BT,  delivered median download speeds of at least 30 Mbps in 15 metro areas compared to the 11 it recorded in the previous round of testing (2H 2018).It also recorded speeds faster than 40 Mbps in four of those 15 markets.

In  Birmingham it recorded its fastest median download speed of 45.7 Mbps.

Vodafone’s improvements in the latest round of testing by RootMetrics can in part be attributed to its network investments.

Its recent deployment of 4G LTE carrier aggregation technology has helped improve its speeds and offer excellent reliability in UK towns and cities.

Not only was Vodafone one of only two operators to record download speeds above 40 Mbps but also it led the way with the single fastest speed across all testing: its 51.7 Mbps speed in Liverpool was the fastest recorded in the UK.

Three’s reputation for being consistent and dependable is reaffirmed in RootMetrics’ testing where it continues to provide users with outstanding call and data reliability in nearly every area tested.

Its speed is also solid, although the operator has the smallest 4G LTE footprint of all operators.

Three was on 4G LTE during at least 90% of tests in just 2 out of 16 metro areas, whereas all other operators were on 4G LTE at least 90% of the time in all 16 areas.

Although O2 fails to rank above third or fourth in any test category in metro testing, its reliability remains strong.

It achieved Excellent data reliability for getting connected in 14 of 16 areas, giving consumers another alternative when deciding which operator to select.

The operator is well known for offering a good customer experience and with additional investment in its technology in 2018, we expect to see O2’s speeds improve in the next set of tests.

EE won or shared the top spot in every test category. Its performance remains outstanding and the operator delivered the fastest aggregate median download speeds across the entire UK and within each of the four nations.

O2’s success is generally limited to Northern Ireland, where it ranks first for text performance in the country.

In Wales, Three shared the spoils for network reliability and call performance whilst its performance across the UK remains steady despite it falling in the rankings.

Vodafone, meanwhile, solidifies its position as a strong second place in home nation testing. It made considerable improvements at a home nation level, with fast speeds and improved performance in Wales.

5G promises much faster speeds in metro areas

Capacity can be stretched thin in major cities such as London, Edinburgh and Birmingham, with some spots performing better than others in these markets. While speed and reliability results look positive across UK towns and cities, the advancement of 5G will take mobile connectivity to another level.

RootMetrics has recently tested 5G performance in South Korea and the results from initial 5G deployments match the speeds we have read about for months – indicating good things to come when 5G fully launches in the UK.

The early testing shows signs that 5G will bring improved speeds and a much smoother data experience to users across the UK’s towns and cities.
