UK mobile operator EE has filed a formal complaint with the Advertising Standards Authority (ASA) over rival Three’s “real 5G” marketing claims.
Three has been promoting itself in newspapers and on social media as the only UK operator offering “real” 5G. Under UK advertising rules, claims of superiority must be supported by clear evidence, and EE has challenged whether Three’s advertising meets that standard.
Three’s marketing is not without foundation: the operator acquired 140MHz of mid-band spectrum suitable for 5G, including a single contiguous 100MHz block. Three argues this spectrum position enables peak speeds up to twice as fast as any rival at launch, while its nearest competitor, Vodafone, holds around 50MHz of comparable spectrum.
Global standards bodies such as the ITU have stated that delivering “true” 5G benefits typically requires 100MHz of 5G spectrum, which is the basis for Three’s claim of superiority in campaign materials. Three’s CEO Dave Dyson reinforced this position in June, saying the company would be the only operator in the UK capable of offering “true 5G.”
However, EE’s complaint to the advertising watchdog focuses on the fact that Three’s 5G rollout remains limited and relatively untested in real-world conditions. While Three’s spectrum holdings and technical specifications look strong on paper, consumer experience depends on network deployment, coverage, capacity, and congestion—factors that can differ substantially from theoretical capability.
Three has recently launched its first 5G home broadband service in London. Early speed tests show impressive results, but those figures reflect an initial, small-scale rollout with low congestion, and therefore may not represent typical performance once coverage expands and more customers connect.
By contrast, EE has been operating its own 5G smartphone service in London, with published tests averaging around 200Mbps download in some locations. Those tests were carried out in different places and different service types, so they are not directly comparable, but they illustrate that multiple operators already offer consumer 5G services in the UK.
The ASA confirmed it has received five complaints about Three’s advertising, including a submission from EE’s parent company, BT. EE accused Three of deliberately misleading consumers, saying, “Three’s claim to be the only real 5G network is entirely false. Our customers have been using real 5G since we launched the UK’s first 5G network.”
Launch plans across the UK vary by operator. EE and Vodafone have announced fewer than 20 initial launch locations this year but already report live networks in around seven cities each. O2 plans to roll out in six cities this year and expand to about 50 by summer 2020. Three has announced ambitions to launch 5G in 25 cities before the end of 2019.
Ultimately, the ASA will need to assess whether Three’s advertising claims are sufficiently clear and supported by evidence so that they will not mislead consumers. Key considerations include the definition of “real” or “true” 5G, the relevance of spectrum holdings to customer experience, and the extent to which limited initial rollouts can justify broad comparative marketing statements.
