• Global Wireless Solutions’ research and testing of UK mobile networks reveals that operators meet customer expectations on mobile network speed over 96% of the time
  • Despite this, over 1 in 2 (56%) encounter problems with their mobile network
  • Consumers call for greater emphasis on network reliability as reliability is ranked as being more important than speed at a ratio of 40:1
  • O2 retains the top spot as the UK’s most reliable network, performing best in 18 of 36 cities and towns tested, followed by EE, Vodafone and Three
  • Liverpool wins most reliable city for mobile network performance, with Leeds ranked the worst

LONDON, 3 February, 2020: Global Wireless Solutions has today released the results of its most extensive nationwide customer experience test of mobile network performance to date. The detailed assessment involved GWS’ engineers collecting close to one million data and voice task tests on iOS and Android devices, alongside nationwide focus groups conducted in partnership with Jigsaw Research, and consumer research polling over 2,000 smartphone users through YouGov. The assessment is the only study of its kind to combine controlled scientific network testing with a deep analysis of consumer behaviour and expectations of performance.

With speed often cited as a key measure of network performance, the report has identified that the ‘sweet spot’ of network speed is between 4-6 seconds as nearly 8 out of 10 deem this to be an acceptable time to wait to complete mobile based activities such as loading news and other websites. Using this metric as a benchmark, GWS’ engineering level test data across the UK highlights that typically operators are reaching this speed 96% of the time.

But despite this, the online YouGov consumer polling reveals that 56% of consumers report that they ‘usually’ encounter problems with their mobile network. When looking at issues that people regularly encounter with their network, websites and apps failing to load impacts almost one in three (30%). In addition, 21% report poor voice quality, 19% say calls don’t connect and 19% say calls drop mid-call – all areas which contribute towards network reliability. The results therefore call for greater focus to be made on network reliability, looking at this as a core measure of network success.

This is further highlighted in the research which reveals that 41% now consider network reliability to be more important than speed, compared to just 1% who say that speed is more important to them than reliability – casting doubt on the ongoing emphasis on speed as the core metric when benchmarking network performance.

O2 retains top spot as UK’s most reliable network and EE most improved (see Fig. 1)

On this basis GWS has focused its GWS OneScore rankings on network reliability, revealing that O2 wins the UK’s Most Reliable Network for the second year running, as the operator ranks top in 18 out of 36 locations tested in the UK. The second most reliable network is EE which scored most reliable in 14 locations making it the most improved operator for network reliability.  Vodafone is ranked top in just four locations, but did record more second place finishes than any other operator. Three did not rank as being the most reliable network in any of the cities and towns tested.

When looking at the regional rankings (which combine the results from all operators), Liverpool and Cardiff are ranked the most reliable cities for mobile network connectivity, whereas Leeds, Edinburgh, Sunderland and London score worst.

Dr. Paul Carter, CEO of GWS commented: “The need for speed is an ongoing conversation in the industry and seems to be the de facto benchmark when measuring network success. But that model is broken – while the advance of 5G brings with it exciting innovations that will undoubtedly change the way we use our phones, just like 4G did a few years ago, using your smart phone is not a race. Consumers are not just using their phones for speed hungry activities. They use their phones for a wide range of activities – from calls and messaging to life administration tasks and shopping. While people place greater emphasis on the importance of reliability, 36% of smartphone owners do still feel that speed and reliability are equally important. Speed and reliability need to co-exist and operators need to weave together a complex tapestry, otherwise known as the “network,” to ensure they are delivering on all fronts for consumers, not just speed.”

Voice speaks up

The study reveals that voice calling retains the top spot as the most important phone function for the second year running, as ‘making and receiving phone calls’ is the most important function of their phone. 44% said that calls always connecting when they dial was “extremely important” to them, calls dropping infrequently is considered “extremely important” by 37%, while voice call quality was listed as “extremely important” by 38% of consumers. By comparison, these voice call related concerns are 2 to 3 times more important to consumers than data speed concerns; speeds for uploads and downloads are considered extremely important by only 15% and 24% respectively.

Meanwhile, coverage continues to be a key area for operators to improve upon, according to UK smartphone users. When asked to select one area for improvement by network operators, over a quarter (28%) reported the desire for increased network coverage, as opposed to just 8% who wanted to see faster data speeds than they currently experience. In addition, when selecting a new plan, over half (54%) of people said that network coverage would be an important factor in their decision – more than double the amount of people who would consider network speed (26%). Once again, voice calling appears to be a key reason behind consumers’ desire for increased coverage – more people (31%) said that a lack of mobile network signal was most frustrating when they needed to make a phone call than in any other situation.

Dr. Paul Carter, CEO of GWS continues:  “We’ve conducted extensive focus groups, surveys and real-life testing to try and understand how people are really using their phones and to identify the ‘sweet spot’ for speed. After all, what difference does it really make if your network is a few megabits faster if you can already stream your favourite video and open apps without issues, but are still struggling with dropped calls? It’s clear that consumers don’t consider all areas of network performance to be the same, with voice ranking top, which is why we feel these insights are critical to helping operators build and deliver the best networks possible.”

Methodology

GWS conducted this series of tests to evaluate mobile network performance across the United Kingdom. A total of 936,249 data and voice task tests were conducted to evaluate the network performance of EE, O2, Three and Vodafone in 36 major cities and towns and roads, in 2019. The tests were conducted using the GWS OneMeasure App running on iPhone devices, Rohde & Schwarz’s Freerider SW using Samsung Galaxy devices, and the GWS Mobistat data evaluation and reporting platform.  

GWS worked with Jigsaw Research – an international strategic insights agency – to conduct a series of in-depth qualitative focus group sessions with UK smartphone owners aged 18+ across the UK.

GWS conducted its broader quantitative consumer polling with YouGov Plc.  Total sample size was 2117 adults, of which 1,913 have a smartphone. Fieldwork was undertaken between 20th – 21st January 2020.  The survey was carried out online. The figures have been weighted and are representative of all UK adults (aged 18+).
